Vapes usually contain flavorings to provide a taste and experience that is acceptable to existing smokers. However, the best choice remains to quit cigarettes and nicotine completely.

Is vaping safe?

Unlike smoking, vapes do not burn tobacco, so—when scientifically substantiated—they have the potential to emit significantly fewer and lower levels of harmful and potentially harmful constituents compared to cigarette smoke. That’s because it’s the burning of tobacco that causes the production of the vast majority of harmful chemicals that are the primary cause of smoking-related diseases. However, these products are not risk-free and provide nicotine, which is addictive. Each product should be scientifically assessed.

Is vaping less harmful than cigarettes?

What am I inhaling when I vape?

The vapor produced when vaping is mostly vaporized glycerin and propylene glycol, along with the other ingredients contained in the e-liquid. The ingredients used in each vaping product varies. Check your product to see the list of ingredients.


What is e-liquid/vape juice, and what does it contain?
