It's not unheard of for someone to have the opinion that the consequences of drug's legal status is more harmful than the drug itself.
I doubt being sentenced to 10 years in prison over selling weed is going to be less harmful than any negative effects observed in this study.
There are other effects, effects on the brain and on sleep quality, for instance, that are not mentioned in this study. Effects on the lungs and cardiovascular system.
None of that has anything to do with 10 years in jail to me. Life sentences for possession are stupid and Boomer.
I mentioned it elsewhere, but where is the panic over prescription drugs and their harmful side effects?
This is a non story. Marijuana is popular because it's potent. Compare it to other legal drugs, the obvious being alcohol, and again tell me about the relative harm.
