Well said, Tam!
Vaping for "competition" or "fun" is one of the main reasons vaping is under-fire from the FDA and the court-of-public-opinion... Vaping is an excellent way to get away from smoking cigarettes (or cigars, pipe, etc.), but if you never actively smoked, you should not even consider vaping. Vaping is not a "cure" for damaged lung tissue, it is merely a (very) effective alternative smoking cessation device to the inferior offerings by the pharmaceutical companies (patches, gums, inhalers, etc.).
