Mostly because I don't believe that enough research has been done,and my dad is a retired DEA officer.My anecdotal evidence from his stories and experiences is something I think I should put first infront of a project that may be wrong.Plus,way back in the early 1900s,cigarettes were thought to be completely fine and could even cure cancer but look where they are now.Until we are absolutely certain that weed is a safe drug and can be consumed then we shouldn't jump the gun on this one.We should wait until conclusive evidence is achieved. But even then,WHY DOES IT SEEM THAT THE ONLY THING US AMERICANS CARE ABOUT IS WEED?Its outrageous.We have children starving in Africa and riots and huge debt but all the stoners or conversations care about is weed.Its sickening.Weed is a luxury item you shouldn't be worrying about.I don't even like getting into these arguments because it's absolutely a waste of time and money.If they outlawed tobacco and alcohol I wouldn't care because it affects my life about 1% if my time.Rant over
