I can count on one hand the number of times I drink alcohol every few years, and I agree. Let's fund detailed studies on the effects (good and bad) for everything. Whataboutism shouldn't be a reason to just let something that could have long-term negative consequences on the mind be blindly advertised as safe. My argument isn't about legality, moreso educating the public about consequences, we do this with cigarettes, and I assume eventually we have to extend vaping to have similar messaging as well.
Legal marijuana in the states is insanely tweaked and modified in terms of THC in order to comply legally, even people I know who have smoked their whole lives feel uncomfortable touching the stuff because its just not even organic anymore.
I think we're overlooking too many things.
