I have a strong worries that our current generation will have a similar huge reckoning with marijuana.<p>We are already seeing studies that show regular marijuana use is correlated with permanent decreases in intelligence, memory loss, motivation, and mental health. And anecdotally, this seems very apparent in my peer group. And Americans are using copious amounts of the stuff right now, and younger than ever before.<p>I&#x27;m not against legalization by any means, or free of my own vices. But the risk in 50 years of people saying &quot;we should have known better&quot; seems really high.
