My Whole Viewpoint........
Drugs such as Heroin and Cocaine have to be DERIVED from a plant, processed etc.
Crystal Meth has to be cooked, processed etc.
Marijuana is a naturally Growing plant, just like tobacco. And is used in the exact same fashion. You pick the leaves, dry them, smoke them, not too hard.
And Marijuana doesn't ADD anything like nicotine, tar, etc, all natural.
Anyways I strongly believe one of the reasons Pot will never be legalized is the simple fact that too many government officials, police officers etc are making too much money in pay-offs while it is illegal, and they do not want to lose that income
