Vaping has its share of mystery chemicals too, though

the flavorants are fairly mysterious, yeah. we know diacetyl is bad to inhale, we don't know how many others are. but if you DIY, only propylene glycol and nicotine are strictly required. vegetable glycerin and flavorants are optional.

I'd choose even the most mysterious Chinese bathtub e-juice over cigarettes though.

Or, maybe do neither?

I think the argument is that vaping is far more addictive for young people because of exactly what you say. Does not feel harmful and they end up very addicted at higher doses of nicotine than cigarettes
