Should marijuana be decriminalized?

Our government is in such denial over marijuana that physicians are even discouraged from prescribing Marinol which is basically synthetic delta-9-tetrahydrocannabinol or delta-9-THC. Yes the stuff that gets you stoned. Which has been found to be extremely effective [under a physicians care] is treating anorexia, nausea ,chemotherapy and glaucoma just to name a few.
