Question for David Brooks, Ruth Marcus, Joe Scarborough, and other opponents of cannabis legalization:
It seems likely that very heavy cannabis use starting in adolescence and continuing for many years can lead to measurable decreases in some cognitive abilities. It is possible that occasional use might also cause damage, but right now there’s no strong evidence to back that claim.
On the other hand, it is certain that participation in high school and college football leads predictably to brain damage.
So: If cognitive harm from cannabis is a good reason to support continued criminalization, would you support a ban on high school and college football? And if not, why not?
