A child psychiatrist I know is adamantly against teen use of marijuana, says it is destructive of brain development. Says alcohol is a problem too, but he’s more worried about marijuana use.
Thanks for making that point.
It’s a common (and very true) argument against marijuana.
Since teens have been reporting for many years that they can get cannabis more easily than beer or cigarettes, evidently it's banning cannabis for adults that hurts teens - by putting cannabis in the black market, beyond the reach of effective regulation such as age limits.
