You can try to debate all day long about how there are many negative affects of weed, but the evidence that is against it has been, in most cases, not all, proven wrong. FOR THE MOST PART weed is a safe substance. Compared to alcohol and tobacco it seems like an angel. Even if you put the number at 50,000 deaths per year from weed (which is not true and never will be), it would still kill 1/6 as many people than obesity kills per year. The only thing that is wrong with weed is its negative stigma. People aren't ready to except weed as a legal substance and that is why it is illegal, not because there are so many negative side effects of it. http://www.wrongdiagnosis.com/o/obesity/deaths.htm http://drugwarfacts.org/cms/?q=node/30#marijuana Oh and I was referring to how it's proportional how many adults use compared to how many younger people use. My point wasn't that the numbers are equal by any means, I was just trying to point out that most people stop or cut back drastically upon graduation from college or getting a solid job in both weed and alcohol.
