Today you're going to learn if vaping is bad for your health.
We analyzed over 40 scientific papers to see what the current scientific consensus is about the health effects of vaping.
On top of this, over the years, we have tested over 300 vaping devices and ran into many potential health risks that are related to improper vaporizer-use. We documented all of these.
The best part?
You're going to learn how to minimize the biggest vaping health risks.
Vaping isn't healthy, and you can never eliminate 100% of the risk. If you want to be 100% safe, don’t’ vape.
No research has ever concluded
that vaping is healthy,
but when comparing vaping to smoking,
there's no easy answer;
the results are mixed.
Some researchers found a significant amount of toxins in vapor, close to what’s found in cigarette smoke.
Other researchers found vaping to be 95% less harmful than smoking.
The only way we can come close to the truth is by analyzing these papers and look at the methods the researchers used to come to their conclusions.
We don't take any single study as truth; Researchers can make mistakes. It's crucial that we use our common sense and years of vaping experience as well.
Most scientific studies that looked at the health effects of vaping looked at e-cigarettes.
There are a few studies that looked at vaping marijuana as well, and the consensus of these studies is that vaping marijuana is 100% a healthier choice than smoking it (not 100% healthy though, you still risk inhaling toxins).
So if you smoke marijuana, don't wait, get a quality dry herb vaporizer.
All the studies which you'll read about next refer to ‘e-cigarette' type of vapes.
This is the camp that found notable negative health effects related to vaping.
This is not the camp that thinks:
If you want to quit smoking, of course, it would be healthiest to just quit cold turkey.
But quitting smoking cold turkey has proven to be difficult for some.
If vaping is less harmful than smoking, it still could be a viable way to quit smoking for those who have a hard time quitting cold turkey. In that sense, a vaporizer could be seen as a harm reduction tool.
That said, let’s dive right into the studies.
In 2018 researchers looked at the presence of heavy metal compounds in e-cigarette vapor.
They found that the coils in the e-cigarettes that they tested, leak toxic amounts of heavy metals when they get heated.
The research concludes as follows:
Vaping could expose you to heavy metal concentrations, which are as toxic as you would get from smoking regular cigarettes.
We also see large variability in heavy metal concentrations between different e-cigarettes.
This means that certain (as of now) unknown variables have a large influence on heavy metal concentrations in vapor.
The next step is to study which variables influence heavy metal concentrations in vapor the strongest, and how these variables can be controlled to reduce heavy metal concentrations in vapor significantly.
Will release much lower concentrations of heavy metals compared to smoking cigarettes.
In 2018 researchers did a survey-based study to look at whether e-cigarette use was associated with an increased risk of heart attack.
Looking at the title of this paragraph, the result of their study shouldn't surprise you:
Daily e-cigarette use was associated with an increased risk of heart attack.
Diving deeper, they found that:
Compared to someone who never used an e-cigarette in his/her life, a daily e-cigarette user had a 1.7 increase in odds of suffering a heart attack.
When they compared smokers with non-smokers (based on earlier research), they saw the following:
Compared to someone who never used a normal cigarette in his life, a daily cigarette smoker has a 2.7 increase in odds of suffering a heart attack.
As you can see, smoking is associated with a higher heart-attack risk than vaping.
But the 1.7 increased heart-attack risk associated with daily e-cigarette use is alarming nonetheless.
Interestingly enough, former and someday e-cigarette use was not associated with having an increased risk of a heart attack.
Former and some-day (regular) cigarette smokers, on the other hand, do have an increased risk of a heart attack.
The highest risk of heart attack was associated with persons who used both e-cigarettes and regular cigarettes daily.
This last finding suggests that e-cigarette use is an independent risk factor for heart attack, on top of regular cigarette use.
Daily e-cigarette-use is associated with an increased risk of a heart attack.
Survey-based studies aren't the most trustworthy studies to come to hard health-based conclusions.
But it’s probably safe to say that:
The more your vaping is contributing to an increased risk of a heart attack.
Based on this study, we can say that:
If you want to reduce heart-attack risk to the best of your ability, don't vape or smoke.
But if you're going to vape:
Based on this study, the researchers can't prove that e-cigarette use is a cause for increased risk of heart attack, because the nature of survey-based studies is such that it can only show correlations/associations. But we can't rule out that vaping is a cause for increased risk of heart attack either. Further research should make clear whether this is the case.
But if you want to be on the safe side, don't vape.
Note that it's also unclear what types of vaporizers and what types of vaping conditions were more strongly associated with an increased risk of heart attack.
Below you can find other research related to e-cigarettes and cardiovascular function:
In 2016 researchers looked at the effects of e-cigarette vapor on neutrophils.
Neutrophils are a type of white blood cells which have an essential role in the human immune system.
When neutrophils get activated, it indicates that your body is suffering from inflammation.
The researchers found that e-cigarette vapor causes acute neutrophil activation that lasts up to 6 hours after exposure.
This indicates that e-cigarette vapor has a pro-inflammatory effect on the body.
The researchers think this inflammatory effect is caused by different toxins that they found present in e-cigarette vapor.
Two of the most important toxins that they found are:
Acrolein is also found in cigarette smoke. The researchers think that the acrolein in e-cigarette vapor is produced by heating glycerol, a compound found in most e-liquids.
Styrene has been linked to airway inflammation. The researchers think styrene might have a pro-inflammatory effect when inhaled through e-cigarette vapor.
Vaping has at least some inflammatory effect on your body, and especially on your airways and lungs.
The question is to what extent this inflammatory effect depends on:
A next step would be to compare the inflammatory effects of vaping vs. smoking and see if the inflammatory effects of vaping are reducible by adjusting different variables like e-liquids, vaping conditions, and vaporizer type.
The same researchers of the study above found various potential carcinogens present in e-cigarette vapor:
But there’s more.
In 2015 researchers (Jensen et al.) shook up the vaping world.
They found that compared to smoking regular cigarettes:
Yes, you read that right: 15 times!
They found that the heating of propylene glycerol or glycol, which is an ingredient found in most e-liquids, can lead to a large concentration of formaldehyde and formaldehyde-releasing agents in your vapor.
Formaldehyde is a known degradation product of glycerol and glycol. It's classified as a group 1 carcinogen by the International Agency for Research on Cancer.
The researchers tested different voltage levels with their vaping gear (an unknown ‘tank system’ e-cigarette with a variable voltage battery).
They found that at 3.3 volts the vapor didn’t contain any formaldehyde-releasing agents.
But vaping at 5 volts, they found such an alarming concentration of formaldehyde and formaldehyde-releasing agents, that they concluded vaping could increase the risk of cancer up to 15 times compared to smoking.
The methods used in this study to come to these conclusions have been criticized in different scientific articles (more on that later).
In 2016, Sleiman et al. found that vaping exposed users to levels of aldehydes very comparable to smoking.
Aldehydes are a group of organic compounds, some of which are known to be harmful to human health, like:
At high voltages (4.8), they found that with their tested devices:
Vaping exposed users to higher concentrations of formaldehyde and acetaldehyde than smoking cigarettes.
Both formaldehyde and acetaldehyde are known carcinogens.
Dr. Farsalinos et al. replicated this study, making sure that they generated no dry puffs.
They also included a new-generation atomizer in their replication study. They compared the aldehyde emissions of this new-generation atomizer to the ones used by Sleiman et al. (2016).
They came to very different conclusions (keep reading to see their results).
A more recent study done in 2018 (Sumburova et al.) looked at aldehyde concentrations in exhaled e-cigarette vapor.
They found a 2-125 times higher concentration of formaldehyde and acetaldehyde inside exhaled e-cigarette vapor compared to regular air.
The researchers further note that the recruited volunteers used their personal e-cigarette devices. This suggests that the high concentrations of formaldehyde found in e-cigarette vapor of the earlier 2015 study (study 2: Jensen et al.) are not exclusive to unrealistic laboratory settings in which dry puffs are generated.
The researchers themselves acknowledge that there are some major limitations to their study.
First of all, their sample size was limited (12 e-cigarette users).
They also admit there's a massive variation in the measured aldehyde concentrations between different users.
They attribute this considerable variation in aldehyde-levels to differences in vaping conditions like:
Next, you'll learn which vaping variables are responsible for releasing such high levels of aldehydes.
Here's the deal:
The findings of the studies above are alarming.
But to understand these results, we have to know how these researchers exactly came to these results.
What methods did they use?
There have been several researchers that criticized the methods used in these studies. The most notable of these researchers is Dr. Farsalinos.
Dr. Farsalinos released several papers (for example here and here) critiquing some of these studies, pointing out the fact that Jensen et al. (2015), used abnormal vaping conditions which are almost never present in regular vaping.
With these abnormal vaping conditions, he refers to the well-known phenomenon of ‘dry puffs.'
Dry puffs are well known with vaping enthusiasts, but less so with researchers.
Dry puffs occur when you heat the coil in your atomizer, without enough e-liquid in it to produce vapor.
It completely dries up the wick in the atomizer. Instead of vaping, you burn any left-over e-liquid, creating very hot ‘vapor' that not only tastes horrible but also feels too harsh on the throat.
Anyone who has been vaping for some time knows what dry puffs are and tries to avoid them like the plague.
This (or a combination of all) is how you avoid dry puffs:
Dr. Farsalinos showed in 2015 that under regular vaping conditions (without ‘dry puffing’), e-cigarettes produced 30-250 times lower levels of aldehydes compared to regular cigarettes.
He also showed in the same study that the only way to create alarming levels of aldehydes with e-cigarettes is to overheat the e-liquid in the tank, which is what happens with dry puffs.
Dr. Farsalinos further stresses that:
How much power you can use with your vaporizer before there’s a significant increase in aldehyde emissions is highly dependent on:
The more e-liquid and power your vaporizer can handle before it starts producing dry puffs (and with dry puffs come the aldehydes).
Another 2017 study found that aldehyde emissions are alarmingly high when e-cigarettes operate at a temperature of 350°C (662°F) or above. This study also found that aldehyde emissions drop drastically when your vaporizer operates below this temperature.
Now, here's the kicker:
Not every vaporizer has got temperature control integrated as a technology. This means it's not always easy to know what temperature your coil gets.
To get the benefits of low temperature vaping, I highly recommend getting a box mod with temperature control to power your atomizer (vape tank, RDA, RTA or RDTA).
In 2016 researchers (EH Ji et al.) found that vapor emitted by electronic cigarettes potentially caused cytotoxicity to human oral keratinocytes via oxidative stress response.
Keratinocytes are cell types that act as the major barrier to all sorts of cell injury caused by different types of compounds ranging from:
They’re basically the first line of defense in your mouth against toxic agents.
Their theory is that vapor emitted by electronic cigarettes contains toxic substances like:
That cause oxidative stress and inflammation and thus damage protective cells in your mouth.
They further found that the longer the duration of the puff, the higher the ‘Particle Number Concentration’ (PNC).
PNC can also be defined as nanoparticles. According to these researchers, PNC is highly related to vapor toxicity.
The higher the PNC in vapor, the higher the toxicity.
It’s important to note that the researchers don’t make any conclusions about what ingredients in e-liquids are responsible for this inflammatory effect.
Also in 2016, researchers (Sundar et al.) found that especially flavored e-liquids
What this means in layman terms is that:
Flavored e-liquids, when heated and inhaled, damage the connective tissue located around the roots of your teeth.
The same study further found that flavored e-liquids caused
If you’re wondering what this means, it means that the flavored e-liquids caused inflammation and DNA-damage to the gums.
It’s clear that e-cigarettes can be a risk for your oral health.
How big this risk is, compared to smoking for example, still needs further research.
We also don't know what e-liquid ingredients and what vaping conditions cause the highest risk to oral health.
Flavored e-liquids contain many different ingredients.
My theory is that at least some of these tested e-liquids were contaminated with:
Both diacetyl and acetyl propionyl have been shown to be toxic to humans.
But it could also very well be possible that there just are ingredients present in ALL e-liquids, which pose a health risk to your oral health.
Further research should point out if that’s the case.
This is not the camp that thinks:
Some of these researchers only point out that vaping is less harmful than smoking, and could, therefore, function as a smoking cessation method.
That said, let's dive right into the studies.
In 2015, Public Health England, an executive agency of the Department of Health and Social Care in the United Kingdom, came out with a study claiming that vaping is 95% less harmful than smoking.
Their study was a review study, and they based their findings on the review of over 180 studies related to vaping, e-cigarettes and smoking.
This is probably the largest study that looked at the effects of vaping as of yet.
They analyzed various studies that looked at carcinogen- and toxin-levels inside e-cigarette vapor. What they saw was the following:
One of the biggest reasons that makes vaping much less harmful than smoking is related to the absence of 2 toxic compounds/compound groups which are found in regular cigarette smoke:
They argue that these are two of the most harmful compounds in cigarette smoke.
After analyzing 180 studies, they found that there was a 90-95% reduction in cancer-causing chemicals in vapor (compared to cigarette smoke).
They also admit that 95% is not a precise scientific number and dependent on various factors. But it’s a good number to give you an idea about the health benefits of switching to vaping.
They further argue that because of this massive reduction in cancer-causing chemicals, vaping causes almost no risk to bystanders.
‘Secondhand vapor' is not a real health risk according to these researchers.
In 2018 they provided an update to their initial study. They still stand by their finding that switching from smoking to vaping results in significant health benefits.
Some other noteworthy findings of this update are:
What's the bottom line?
They stand behind their original research done in 2015 and still think vaping is significantly less harmful than smoking.
This one is again from one of the most noteworthy experts on vaping science: Dr. Farsalinos.
Troubled by the results of some previous studies (which you can find in chapter 1) that state vaping exposes users to as many if not more aldehydes than smoking, Dr. Farsalinos et al. (2018) decided to replicate one of these studies under realistic (no dry puff) conditions.
They also included a new-generation atomizer (the Nautilus Mini) to check for aldehyde levels with newer generation vaporizers.
What they found contradicts the earlier studies from:
If you forgot, these are the studies that found high levels of aldehydes in e-cigarette vapor.
Dr. Farsalinos and his colleagues found that these researchers used unrealistic vaping conditions like:
To replicate the earlier study of Sleiman et al. (2016), Farsalinos et al. tested under the following conditions:
They also had two experienced vapers check for dry puffs.
Below you can find their most noteworthy results:
As long as you use the proper vaping conditions, which means:
We can say that based on this study, vaping will reduce your aldehyde exposure by 95% compared to smoking.
In 2017 researchers (Shahab et al.) looked at important carcinogen and toxicant metabolite levels in long-term users of:
This is to my knowledge, the only study which looked at the long-term effects of e-cigarette use so far, so the findings are important and relevant.
The quick summary of their findings:
Based on their study, we can conclude that e-cigarette use under vaping conditions used by the average vaper, is much less harmful than smoking.
They even found that e-cigarette users scored lower on some measures of carcinogens and toxicants, compared to Nicotine Replacement Therapy (NRT)-only users.
It’s important to note that they found that:
This means it's critical that you COMPLETELY cut out cigarettes when vaping.
If you only half-ass it, and that even means smoking 1-2 cigarettes a day, based on this study we can say that you potentially negate most of the benefits associated with vaping.
The researchers further stress is that vaping is not 100% safe if you use e-liquids with nicotine, and to reduce your health risk to 0%, you need to cut out any nicotine products.
In 2015 researchers (McRobbie et al.) looked at carbon monoxide, acrolein and nicotine exposure in smokers who underwent a 4-week quit-trajectory using an e-cigarette.
Half of them managed to stay off cigarettes, and half of them continued smoking cigarettes, although less than before.
By checking the urine of the study participants, the researchers measured acrolein and nicotine levels. The carbon monoxide was measured differently.
They found that the quitters who used only their e-cigarette in these four weeks:
The dual-users also had quite a large reduction in CO and acrolein levels compared to smokers (50% and 62%, respectively). Dual users had a 4- to 6-fold decrease in exposure to acrolein.
The researchers are aware of the limitations of their study. They state there are more carcinogens and toxins in e-cigarette vapor, of which they only studied two (CO and acrolein).
Vaping still exposes you to toxins and carcinogens which have the potential to damage your:
But is vaping less harmful than smoking, and thus a viable way to quit smoking?
Based on these studies we can say that under regular vaping conditions, which means:
Vaping is likely to be less harmful than smoking.
If you want to quit smoking, best for your health would be to quit cold-turkey.
But if you think that’s too difficult, vaping could be a less harmful alternative, among a list of other viable options like:
I want to emphasize that at Herbonaut, we see vaping only as a temporary tool to give up smoking. In the end, best would be if you're both smoke- and vape-free.
We didn't cover all studies related to vaping here; we only included what in our opinion are the most noteworthy.
We also didn’t cover all vaping health risks by analyzing the results of these studies.
There are more health risks associated with vaping.
Luckily, you can avoid most of them with some simple preventive measures, which you'll learn about next.
In the past years, the media has covered different horror-stories about vaporizers blowing up.
In cases like this, it’s almost always the battery that blows up.
While these cases are relatively rare:
Between 2009 and 2016, the U.S. Fire Administration registered 195 instances of batteries catching fire or exploding)…
When your vape blows up, it can cause devastating damage, and in severe cases even kill you.
So, it’s crucial that you understand why this happens and how you can prevent it.
The first question we have to ask ourselves is:
Is this issue really related to vaporizers?
Or is it a problem that comes with improper battery-use?
It’s fair to say that it probably is a bit of both, as you’ll learn now.
Some vaping devices, like mechanical (unregulated) mods, come without any built-in electronic safety protections.
With such a device, you HAVE to make sure that the coil in your atomizer fits perfectly with the ampere rating of your battery.
To make no mistakes in this regard, it's EXTREMELY important that you read up on Ohm's law and understand how it affects your vaporizer.
If there’s no perfect match between your coil and the ampere rating of your battery, you risk overheating the battery, which can result in an explosion.
The exact mechanism responsible for battery explosion risk works like this:
If the coil/atomizer you use needs more amperage than the battery can supply, the strain on the battery is so strong that it overheats and can go into thermal runaway.
If the battery can’t vent when it overheats, the energy can be powerful enough to cause a fire or worse: an explosion.
We highly advise against using mechanical or unregulated mods. Especially if you’re a beginner, please just don't use a mechanical unregulated mod to power your atomizer.
Regulated mods are plenty and cheap these days.
But if you do use one, make sure that the ampere of your batteries matches the ampere need of your atomizer/coil.
First, let’s understand how batteries work (simplified version):
In every battery, there's a positive and negative pole. When you connect these poles, you form a circuit that draws power out of the battery.
And now comes the interesting part:
Any electrical conductor (even keys, and coins) can connect the positive and negative pole in a battery.
What happens when your battery comes into contact with the keys in your pocket and starts ‘powering’ your keys?
Well, because there’s nothing to power (a key draws no power from a battery whatsoever), your keys generate a short circuit in your battery.
A short circuit causes your battery to release a large amount of energy, without it having an outlet.
When energy has no outlet, it can lead to fire and explosions.
Battery short circuit risk is easily avoided by ALWAYS keeping lose batteries in (plastic) cases or rubber/silicone battery-sleeves.
NEVER keep batteries loose and uncased/unprotected in places where they can come into contact with conductive materials like keys or coins.
A vaporizer battery can reach high temperatures.
Two of the causes of a dramatic increase in battery-temperature, you already learned about:
But if you have a vaping device that operates in high-power settings, the battery of your device will reach high temperatures anyway.
The more power your vaporizer uses (in watts or volts), the hotter your device and battery get.
In these cases, it's critical that your vaping device has the right vent holes so that your battery can cool off properly.
If you’re a sub-ohm vaper (you use power-hungry sub-ohm coils operating on a low-resistance, that run on high wattage settings), it’s especially important that you get a regulated mod with:
Luckily, most regulated mods these days come with the most important safety features.
If you’re vaping at sub-ohm levels, you need a lot of battery power.
In these cases, you’re demanding more from your battery compared to when you would vape at above-Ohm or low-wattage/low-voltage settings.
If you want to stay on the safe side as a high-wattage vaper, you should get a regulated mod with safety features like:
First, let’s understand why overcharged batteries are dangerous.
The first reason is that:
If you overcharge your batteries, you stress them so much that they can expand, crack, and leak toxic chemicals.
The second reason is that:
Overcharging causes increased stress on the battery, which can lead to heating issues.
The increased heat, in turn, causes extra stress on the battery, which in turn causes excess heat.
It becomes a vicious cycle and can lead to your battery catching fire or even exploding.
Now that you understand WHY it's dangerous to overcharge your batteries, it's time to learn HOW you can avoid it.
While most vaping devices have:
There's always a minimal chance that the over-charge protection fails.
But this chance gets bigger if you buy devices from no-name brands or try to go as cheap as you possibly can by buying clones for example.
Realize that cheap devices always cut corners somewhere, and it might be the overcharge-protection.
It gets worse:
The chance of failure gets even bigger if you use uncertified or cloned batteries. These batteries handle stress way worse than originals, and are dangerous!
ALWAYS buy officially branded batteries. Avoid clones or no-brand batteries!
Another potential issue you can face is if you have a multiple-battery device.
If you want to go for such a device, we recommend getting one with ‘balanced charging'.
Balanced charging is a safety feature which ensures that all the batteries inside your vaping device get charged at the same speed.
With balanced charging, never will one battery charge up quicker than the other.
If one battery charges up faster than the other, it can easily lead to overcharging.
The last potential problem you can face when charging your batteries (outside your device) is related to using an external unregulated charger.
Unregulated chargers don’t stop charging when your batteries are fully charged.
Unregulated chargers are rare these days.
But always make sure you have a regulated charger if you charge your batteries outside your device.
Never leave charging batteries unattended.
Never leave your device charging overnight.
Always go for a vaping device with safety features like:
And if you charge your batteries outside of your device, ALWAYS use a regulated charger.
If you use the wrong charger, the effects can be a stressed and overheated battery which potentially sets itself on fire.
Usually, with your vaporizer purchase, you will get a charger that's designed to be used with your vaping device and its battery.
And while you could plug in your phone's or tablet's charger into most vaping devices, it's not recommended for a reason.
By using the wrong charger, you could kill the battery or worse:
Set it on fire.
NEVER charge your device with a charger other than the one you’ve got with your vaporizer purchase, unless explicitly stated otherwise!
In case you did accidentally charge your vaping device with the wrong charging cable/charger, make sure to let the battery cool down for at least 20 minutes before you use it.
If you use the wrong battery in your vaporizer, it can lead to significant heating problems and even explosions.
There are two ways you can use the wrong battery for your vaporizer:
Both of these examples are dangerous.
If your atomizer/coil is designed to drain 20 amps, but can only drain 10 amps (because your battery can't provide more), AND you're using an unregulated mod…
It might very well lead to an overheated battery that explodes in your face while you’re using your device.
But even if you're using a regulated mod, you want to make sure the ampere requirement of your coil/atomizer matches with what your battery provides.
Otherwise, you'll just have a crappy vaping experience.
If you don't want to take ANY risks, ALWAYS use a regulated mod for your atomizers and coils.
ALWAYS use the right batteries for your device. This means batteries that are officially approved by the manufacturer of your vaporizer.
NEVER buy cheaper battery clones, and ALWAYS buy them from authorized dealers.
While most vaporizer manufacturers design their vaporizers with materials that can withstand high temperatures…
And materials that don’t leak any toxic chemicals…
It’s important to make sure your vaporizer is designed with the right materials in the right places.
Especially the parts of your vaporizer that get really HOT, like:
NEED to have heat-resistant materials around them.
But more importantly:
It’s crucial that the heating element itself is of the highest quality materials as well.
Heating elements like coils have been shown to leak heavy metals. And heavy metals are bad news for your health.
About the materials around the heating element:
This is especially important with dry herb vaporizers. Atomizers and e-cigs often have a straightforward coil-based design in which the heat can easily be isolated and dispersed.
Most dry herb vaporizers use much more power than the average coil-based vaporizer like e-cigs.
The challenge with portable dry herb vaporizers is packing as much as possible power into an as small as possible size.
This challenge is precisely what can lead to an irresponsible design (from a health perspective).
Potent heating elements, create lots of heat. And since portable dry herb vaporizers are so small, most of the materials need to be heat-resistant.
But heat-resistant materials are often expensive.
Vaporizer-manufacturers try to cut costs wherever they can. Sometimes they design a vaporizer without enough heat-resistant materials in the right places.
Of course, there’s more to designing a safe vaporizer. The materials themselves need to be:
There's a whole lot cover on dry herb vaporizer design, which you can read about here. But the most crucial thing is that you've got heat-resistant and non-toxic materials in your vaporizer.
Most of you aren't looking to analyze a vaporizer from top to bottom on its design and the materials used in it.
If you want to stay on the safe side, always buy your vaporizer from a reputable manufacturer and reputable vendor.
Don’t buy your vaporizer from auction-like stores like E-Bay or Alibaba.
There’s a TON of cloning going on in the vaporizer world.
Clones have a terrible reputation for design-/material-safety.
Don’t gamble with your health! Click here to see a list of vape stores that we recommend.
The biggest health risks related to the technology in your device are about:
The problem with vaping at a too high wattage- or voltage-setting is related to the temperature.
If you vape with too high of wattage or voltage, the temperature of your coil and e-liquid will reach levels where they might leak toxins.
Above certain temperature-levels, you will expose yourself to a high level of toxins.
Luckily, most dry herb vaporizers and wax/dab pens have different temperature settings ranging from low to high.
The only vaporizers that come with these fixed temperature/wattage/voltage designs are the e-cig type of vapes, mostly:
A fixed temperature/wattage/voltage doesn’t have to bad for your health…
IF the temperature of your coil or heating element is below the max temperature which researchers found is correlated to a massive increase of toxins in your vapor…
This Max-temperature is different for dry herb vaporizers and e-liquid vaporizers.
While there are no exact guidelines to wattage/voltage limits that are considered relatively ‘safe’ (it's highly dependent on the power requirements of your atomizer/coil)…
It’s safe to say that after reaching the Max-temperature which is considered ‘safe,' the higher your temperature, the more toxins you will produce in your vapor.
Now you'll learn what these limits are for both dry herb vaporizers and e-liquid vaporizers (e-cigs).
If you want to reduce toxins in your vapor as much as possible, always go for a variable temperature/wattage/voltage vaporizer AND stay as low as possible.
With dry herb vaporizers we recommend not going above 392°F (200°C). Read our full guide on dry herb vaporizer temperatures to learn everything about weed vaping temperatures.
With e-cigs (box mods, vape pens, cig-a-likes), we recommend not going above 350°C (662°F). Best will be if you get a regulated box mod with temperature control to stay below a fixed temperature. It's a fantastic safety feature, and in my opinion, the safest way to vape.
Short answer: no.
Understanding WHAT you put in your vaporizer to vape is also highly relevant if you want to reduce the health risks of vaping.
This is most important for vape juices.
But if you don’t have organically grown marijuana, chances are, you have pesticides and other chemicals on your marijuana.
With marijuana, this risk of vaping toxic chemicals is avoided by getting organically grown weed.
With vape juices, it's a bit more complicated.
Vape juice manufacturers can potentially put anything in their vape juice.
As you read before, there are studies that found e-liquid flavorings can have adverse effects on your oral health.
In the past, there have been e-liquid manufacturers who put known toxins inside their e-liquids, especially:
And even worse:
You've seen one study found that some e-liquids contain heavy metals (chapter 1).
There are enough vape juice manufacturers that prove they have a clean product.
Be smart, and get a clean vape juice, even though the price might be a bit higher.
To prevent vaping contaminated vape juices, ALWAYS get a vape juice/e-liquid that’s:
Read our guide on the best e-liquids to avoid getting contaminated e-liquids.
This is especially important if you vape flavored vape juices. But If you want to minimize risks to the best of your ability, don’t vape flavored vape juices at all!
If you’re addicted to smoking, it’s good to realize that part of your addiction is related to nicotine.
Nicotine is an addictive substance.
Not only is it addictive, but it's also unhealthy.
Nicotine is associated with all sorts of health issues:
Vaping is a less harmful alternative to smoking. But if you keep using vape juices with nicotine, you don’t reduce the health risks associated with nicotine at all.
Not only that, but you keep reinforcing your nicotine addiction. Realize that some pod-based vapes like the JUUL come with proprietary pods that don't have nicotine-free versions. You can't vape nicotine-free with the JUUL.
If this is the only way that you can manage to quit smoking, it still might be worth it to vape e-liquids containing nicotine!
Even though you might not reduce the health risks associated with nicotine, you will reduce your exposure to toxins and carcinogens!
