So this is demonstrably false.
In a survey of high school seniors, in 1976, 64% of them had consumed marijuana in their lifetime.
Among seniors from 2022, just 38% have ever consumed marijuana.
Alcohol consumption is way down.
Cigarette smoking has collapsed, too.
It’s because they’re sitting around by themselves smoking weed. Not a positive shift at all. Society can thrive when there’s lots of social drinking. That’s been proven. But no society of stoners has ever accomplished anything.
