It's one of the few herbal medicines that actually work. Given a choice between Benadryl, Ambien, or marijuana for my sleep problems, marijuana hands down (I don't smoke it due to the possible legal issues). Another issue is even w/ insurance Ambien has a $50 copay, the drug company is going to get paid so long as their drug has a market. Marijuana seriously competes with a lot of drug catagories. Another reason marijuana remains illegal is it is so heavily associated with the counter colture movment in the 60's 70', wether or not it had any direct effect on the magnitude of it, the governmet would rather err on the side of caution as far as risking that marijuana could be a scocial catalyst. It could go on and on, tax dollars, criminalize citizens, medical, ect. So everyone who said it should stay illegal, go fix yourself another drink and think it over again.
