Alright, how about this: why SHOULD it be illegal? It is not physically addictive. It is not deadly (or, not significantly more so than, say, chocolate doughnuts). It has significant POSITIVE effects (medical effects include pain relief and appetite stimulation; recreational effects include a "high" which some individuals find desireable.) Like I said, I don't do marijuana. I just believe it should be legal. Actually, it's proven that the health risks of marijuana are equal, if not greater, than that of a cigarettes. Many experts actually believe that marijuana is equal to 10 cigarettes in terms of health risks. Not only that, but it impairs your judgement.
