Malcolm Gladwell related in a New Yorker (January 12, 2019) piece, Unwatched Pot: Do We Know Enough About Marijuana?:
"Because of recent developments in plant breeding and growing techniques, the typical concentration of THC, the psychoactive ingredient in marijuana, has gone from the low single digits to more than twenty per cent --- from a swig of near beer to a tequila shot."
And as THC levels have increased, there has been increase in the rate of mental illness -specifically among "stable middle-class professionals" that "[...] hardly responded to antipsychotics."
