I don't smoke or vape. They are both bad for your lungs, and smell awful.
I a pharmacist in training will try to assist you. Vape contains nicotine but it is also composed of multiple heavy metals. Propane-Glycerol, lead, chromium, acrolein, and more. It can cause harm to the person doing it and others around them. It is not good for the environment, so as @Snoopy Fan said I do not vape and never will.
