Vaping is less carcinogenic than smoking by a significant degree but it is carcinogenic
Acrolein, a carcinogen, forms in small amounts from the breakdown of glycerin during heating
If a “dry hit” occurs the effect is worsened, acrolein forms in higher amounts, and formaldehyde (another carcinogen) can occur from the breakdown of both glycerin and propylene glycol
Vaping still leads to inflammation and oxidative stress in the lungs and long term use will almost certainly lead to irreversible damage
Harm reduction is important. Vaping is likely better than smoking but it is not yet clear whether that is the case. It is likely the case based on short term anecdotal data from people who have switched but this does not mean that long term use won’t create more severe lung issues over a period of 20-30 years. We don’t know.
In the meantime for further harm reduction to reduce risk you can vape with low temperatures as this mitigates much of the carcinogen risk, you can use reusable devices and frequently change coils and ensure the coil is saturated, and you can use a liquid that is free of flavorings as these present much of the “unknown” variables.
Or you can work to quit. It is challenging. I smoked and vaped, I know it is tremendously hard. But frankly these companies don’t deserve your money. They’re all fucking scumbags
Well said. I smoked a pack a day for 17 years and finally quit a little over a year ago. Lots of people around me quit around the same time but just ended up exchanging the habit for something else like vaping, chewing, or the new fad: nicotine pouches. It made me feel even better to be entirely nicotine free.
For anyone curious, I used nicotine gum from Costco for the first 2 months to help. It tastes like shit and is not enjoyable at all, but I don't know if I could have done it without.
