The advice on vaping is clear. Nicotine vaping is substantially less harmful than smoking and it’s also one of the most effective tools for quitting.
Vaping is not completely harmless, and it’s only recommended for adult smokers to quit tobacco smoking.
Tobacco is lethal, there is no safe usage level. By swapping to a vape, you will significantly improve your health and then you can cut down the nicotine content gradually and on your own terms, until you are no longer dependant.
