Not even close. And Marijuana is less dangerous for society and individuals as alcohol, automobiles, etc. HOWEVER, if we say that anything should be legal as long as it doesn't encroach on someone else's freedom, where do you draw the line with hard drugs such as PCP/Crystal Meth that may increase violent tendencies with the user? I could potentially see many making the argument that legalizing certain things simply hurts the lower class or keeps them in poverty, such as crack, etc. Should there be rules protecting people who aren't educated enough to make good long term decisions for themselves?
