Um, what?
Lysergic acid diethylamide = LSD
Tetrahydrocannabinol = THC
Try again, please.
Edit: Didn't see that this was addressed before I put in my two cents. Ah well.
Regardless, I think it should be legalized, not just decriminalized. In Oregon, possession of small amounts have essentially been decriminalized, and most people I know who have been caught were issued a citation or their stash was confiscated. We also have a medical mj program that is so lax that I could probably get on it simply for having ADHD. Fun times.
