Do vapes and e-cigs produce water vapor or aerosol?
Males/Females Ages 13-25
Vaping device, e-juice

Conclusion: Vapes and e-cigarettes heat e-juice/e-liquid to create an aerosol, not water vapor. An aerosol is a mixture of liquid particles suspended in a gas and contains many toxic chemicals – some of which are the same as those found in cigarettes and cigars. The aerosol produced by vaping is inhaled deep into the lungs. Studies have found that inhaling these chemicals can lead to asthma, inflammation, and even make it permanently harder to breathe. The standard for what we breathe should be clean air, free of toxic secondhand smoke/aerosol.

Chemicals found in aerosol:

*Additional chemicals can be found in aerosol than those listed below
  • Propylene glycol
  • Glycerol
  • Lead
  • Tin
  • Nickel
  • Nicotine
  • Acetone
  • Formaldehyde
  • Acetaldehyde
  • Propanal
  • Diacetin
  • Triacitine

Do flavored vapes contain harmful chemicals?
Males/Females Ages 13-25
E-cig, multi-flavored juices

Conclusion: Don’t be fooled. Flavorings only mask the chemicals in vapes, such as diacetyl and nicotine. Research has concluded that flavored products play a major role in drawing youth and young adults to tobacco products, as they are often mischaracterized as less harmful than non-flavored tobacco products. Additionally, research has found that students who vape in high school are 6x more likely to smoke cigarettes as adults. Don’t get caught in the flavor trap.

Do vapes contain nicotine?
Males/Females Ages 13-25
Vaping device e-liquids (e-juice)

Conclusion: Most e-cigarettes contain nicotine. While some may think they are not vaping nicotine, a 2019 study found nearly all (99%) of e-cigarettes sold in the U.S. contained nicotine. Additionally, over half of the thousands of e-juices available may have inaccurately labeled their nicotine content – some reporting zero nicotine when their products did, in fact, contain nicotine. E-juice manufacturers are not currently required to report the ingredients used in their products. This means vape users do not know what ingredients or how much of a certain ingredient is used in their vape juice, pod, or cartridge.

Do you really need to worry about nicotine?

Your brain continues to develop until you are about 26 years old. Research has shown nicotine impacts teens and young adults – and not in a good way.

  • Nicotine impairs brain development, decreasing the ability to focus and pay attention.
  • Nicotine is an extremely addictive substance, similar to heroin, cocaine, and alcohol.
  • Nicotine is derived from tobacco. When tobacco products are used, such as cigarettes, cigars, and vapes, nicotine is quickly absorbed into the bloodstream.
  • Within 10 seconds of entering the body, the nicotine reaches the brain.
  • A nicotine “buzz” fades quickly and leaves the user feeling tired, down, and wanting the “buzz” again.
  • This feeling makes someone light up the next cigarette or grab a hit of their vape. This up and down cycle repeats over and over, becoming a disease known as addiction. Addiction keeps people using these products even when they want to quit – they lose control.

Why we're here

We don’t think humans should be used as test subjects.
Vapes are products with red flags, unanswered questions, and overstated myths. In 10 or 20 years, we’ll know the results of this Vape experiment, but as the subject, you pay the price. We think that stinks.
We’re not here to lecture, mock, or shame.
This isn’t about being judgmental. We just want to give you information that could be important to you, as well as your friends and family. After that, it’s up to you whether you want to be part of The Vape Experiment or not.
We think the public should be informed.
