In my opinion, if the doctor prescribes it for a real health problems, then I can see it. The problem is just like in any profession, there are doctors that shouldn't be practicing medicine. I can't fathom why a teenager would need medical marijuana. Here in California, medicinal marijuana dispensaries will open for a while, then the FEDS will come in and raid/shut them down. The states can make it legal but, the FEDS still consider it an illicit drug, thus illegal. It will be fun to watch what happens in Colorado and Washington. Me, can't smoke it period, I have a DOT job that gets drug tested. I personally don't care for drugs of any kind, other than ibuprofen.
