so yeah, it's hard. Making it unnatractive is a lot easier procedure with drugs and "bad things", but a machine that makes huge clouds of tutti frutti falvoured smoke is.. wel... fun.
I agree it's super hard, even with pot (again in CA) when it was illegal it was a bit of a joke to me (and a surprise as someone moving from a conservative area where pot use definitely had to be hidden) because if enough people use it even illegally and it's not considered a police priority, then there's no enforcement/repercussion and people use it willy nilly, often publicly.
One, the contrast between Orange County where one would not dare to dream to smoke in public. My (minor) career as a weed smoker was entirely indoors-- late nights and Boards of Canada albums, and whispers of, "Do you know anyone?"
Two, as a cigar enthusiast, how utterly unwelcome I would have been smoking tobacco.
That ignores the fact that cigarettes, which are orders of magnitude more dangerous, do not require such hoops to be jumped through.
If you’re going to make vaping by prescription, you then need to simultaneously ban tobacco outright.
