Re: Bathtub gin
Don't take that too literally. What I meant is that the appearance of a harmful form of a recreational substance, used safely for a very long time, is due to prohibition leading to lack of regulation and the surrendering of the market to criminal enterprise.
No one's ever died from smoking cannabis* but people have had their heads screwed up by the psychotic effect of the THC-heavy varieties which have been bred over recent decades.
* Not "marijuana". That's a name invented during Ansliger's "reefer madness" campaign, to make it sound like a foreign threat and to pander to the period's anti-Mexican prejudice.
