I'll assume you just didn't see this cuz I editted it in:
Still my personal opinion is that drugs can be dangerous and I'd rather them not be completely legalized.
The problem is that making them illegal does jack stuff to prevent their use, all it does it move it's sale to black markets, cost tax money enforcing the ban, and put people in jail
Because unlike weed alcohol can be used at a safe dosage.
Alcohol is far more toxic than marijauna/thc
Deaths from alcohol poisoning are fairly common, deaths from thc overdose are nonexistant
it has long-term effects
Our understanding of marijuana's long-term brain effects is limited. Research findings on how chronic cannabis use affects brain structure, for example, have been inconsistent. It may be that the effects are too subtle for reliable detection by current techniques. A similar challenge arises in studies of the effects of chronic marijuana use on brain function. Although imaging studies (functional MRI; fMRI) in chronic users do show some consistent alterations, the relation of these changes to cognitive functioning is less clear.
