A) we had learned anything At All from Prohibition - we didn't and likely we won't - we love to sanctimoniously prescribe (and proscribe) as much behavior as - the flock can just barely tolerate...
B) Muricans were not so miserably fucked-up over the Corporate bizness hegemony - 24/7, two working for wages of one, (20 years ago) that: they'll take Any substance which allows them to forget the inanity of their infotainment and irrelevance of their 'jobs' in Corporate.
C) Combo of A and B = make it not illegal but, draconian with 40 year sentences for 3x possession for personal use even! Throw cannabis in there too, with Heroin and Anthrax = drive up the prices still higher = send lots of that $$ er abroad.
BECAUSE MURICANS NOW NEED LOTS OF DRUGS! just to *stand* living in emotionally impoverished Murica 2000+ We are the biggest druggies (OTC and Rx = taxed = those are OK!) in history of the world.
Simple as ABC.
