With legalized use around the world...now in states and illegal use for decades..we should have seen major dangers by now.
We didnt study nicotine, caffeine, alcohol, redbull..etc. they all have negative effects.
Aspirin, tylenol ,ibuprofen were and are fda approved for otc...likewise they have negative effects.
I want more research and adilts able to do what they want as long as they dont harm others...for the most part.
