The tobacco companies have bought into the vaping industry, along with a lot of random other corporations and small businesses.

But there's certainly NO reason to vape other than "monkey see, monkey do."

Nothing other than what I said; "monkey see, monkey do." / peer pressure. Same as adults. It's just a really stupid fad.
