The OP asks for a legitimate reason why marijuana should NOT be legalized. So I, JFTR being 100% pro-marijuana (and most drugs, for that matter) legalization, am trying to see things from the opposition’s point of view. The only thing I can come up with is the inevitable damage of DNA, which thereby affects our offspring, or “the future”, and I’d like to know your opinions on that. (I admit freely this would be asking for a spanking, IF this were my position, but it’s the only negative aspect I can think of.)
As it stands, I just cannot see why marijuana is still illegal. If it were legalized, there would be age restrictions, just like alcohol and tobacco, and the government could make money off of it through taxes, just like alcohol and tobacco. The potency could even be government controlled, and maybe they could even research ways to make it less harmful, although it can’t be the physical dangers that keep it illegal; alcohol does the same if not worse to your brain, and cigarettes do the same if not worse to your lungs! By the way, who the hell is the government to tell me I can’t hurt my OWN body anyway? (don’t get me started on kevorkian…)
If there were ANY danger to people other than the user himself, i.e., violent tendencies or impaired driving ability, I could see the legitimacy of an anti-legalization stance. But, in the absence of those effects, we are left only with stupid, flimsy arguments based on fear and tradition.
