What are e-cigarettes?
- Electronic cigarettes (e-cigarettes) work by heating a liquid to produce an aerosol for users to inhale, a process called vaping.
- Also known as e-cigs, cig-a-likes, c-cigars, e-hookah, hookah sticks, personal vaporizers, mechanical mods, vape pens, electronic nicotine delivery system (ENDS)
- E-cigarette liquid consists of a base liquid, flavoring, and often nicotine or THC, active ingredient in marijuana.
- The concentration of liquid nicotine in e-cigarettes is usually higher than traditional combustible cigarettes.
- The liquid is available in different strengths and flavors.
Dangers of e-cigarettes
The lung injury known as EVALI (e-cigarette, or vaping, produce-use associated lung injury) was recognized in the summer of 2019, with cases peaking in September 2019 and steadily declining since then. It can present as progressive lung illness that can result in severe lung injury, hospitalization, and death. Most, but not all, cases have been associated with people using informally sourced THC vape products, such as those bought on the street. Vitamin E acetate, a product used in many foods and cosmetics, has been linked with EVALI and has been found in many street-obtained THC products. Vitamin E acetate is typically safe for ingestion and application on the skin, but research suggests that when it is inhaled it can disrupt normal lung function. While vitamin E acetate seems to be a causative chemical, there is not enough evidence to say it is the only chemical in e-cigarettes that causes EVALI. Most of the flavorings and other ingredients in e-cigarette liquid have not been studied when inhaled and many of the risks with vaping are still unknown.
The aerosol that users breathe and exhale can contain harmful and potentially harmful substances, including:
- Ultra-fine particles that can be inhaled deep into the lungs
- Flavoring like diacetyl (a chemical linked to lung disease)
- Volatile organic compounds
- Cancer causing chemicals
- Heavy metals like nickel, tin and lead
- There is no way to know what each e-cigarette product contains.
Common mild symptoms to watch for:
- Fast or racing heartbeat
- High blood pressure
Common severe symptoms to watch for:
- Slow heartbeat
- Low blood pressure
Recommendations from the CDC:
- Don’t use THC-containing e-cigarette products, especially products obtained from informal sources.
- Don’t add vitamin E acetate, or any other ingredients, to commercially purchased e-cigarette products.
- E-cigarettes should not be used by youths, young adults, pregnant women, or those who don’t already use tobacco products. like Native Smokes
- Those using e-cigarettes should not switch back to regular cigarettes, and should seek help from their primary care provider for other options to quit nicotine use.
