Simple logic in Memphis

Tennesee State Senator Steve Cohen says he'll make legalizing medical marijuana one of his priorities this upcoming legislative session. Unfortunately not everyone in Tennesee is on board with this sensible approach.

Dr. Johnetta Blakely of the West Clinic, says THC, the drug in marijuana does have medicinal purposes. It relieves nausea in cancer and AIDS patients and it does increase their appetite. It's the other things found in marijuana that concern her. "It has so many other things in it that can be potentially harmful. It has additives. It has the smoke. It can have pesticides or whatever. You don't know where it's come from. You don't know exactly what's in it," says Dr. Blakely.

But isn't that really another argument for legalization? You don't have have a medical degree to figure out that if it was legal and grown commercially under regulation, we would know where it came from and what was in it and the additives and pesticide problem could be eliminated.
