MARIJUANA FACTS!???!!!!!!!?

I am currently 17, now I may not be full of wisdom but I know my facts about marijuana and it's benifits and aide effects. Now for y story...I was recently caught, my dad found my pipe and some empty bags. He flipped and tried taking my car away and my pay check( that wasn't happening). Anyway needless to say I played it low for a few weeks, my mom cared but knew she couldn't do anything about it. Weed is not addicting, not harmfull, does not cause cancer of any from,and does not kill brain cells. Marijuana is less addicting then sugar (proven fact by studies at harvard university). If I was a parent of a kid who smokes pot, I wouldn't care, I would smoke with them, but with rules. It's safe then alcohol, ciggarettes and caffeine! If anybody wants to argue their ignorant opinions and there sO called "facts" then watch the movie called THE UNION
