Never done any kind of drugs and don't plan to start but honestly they should legalize it.
I mean prohibition didn't work for alcohol and many crimes are committed by people under the influence of alcohol.
From what I've seen POT mellows people out. Can't say that about the majority of people who drink. Plus there have been some GREAT results using oils from Marijuana that have had the THC(s) (the part that makes you high) removed. It's actually amazing how it works so well for small children who have seizures or other diseases it seems to control the effects of. Do a search and watch some of the videos and I think you'd agree.
Legalize it and tax it is what I would recommend. Just think of how much room we'd open up in our prisons for people who commit much worse crimes. Heck, we could fill them up with our politicians if nothing else.
