It is going to happen. THC will be used to treat patients. Legislators recognize this and are doing everything to stall the process until a manufactured form has been created. Pharmaceutical companies are scrambling to come up with this new device. Dammit, if people insist on using cannabis for medical reasons, they are going to have to buy it.
Somebody needs to make a profit.
It's the American way. Once again, the hand of Pharmaceutical companies are trying to make money off something that you and I could grow for pennies, if it were legal. Much like Marinol was suppose to help cancer victims, the drug companies who are lobbying to keep marijuana illegal, but want to process God's gift to you and me, to make cash for their stockholders. They are still trying to convince the public that marijuana is as cancerous as cigarettes, even though I have yet to hear of any death caused by marijuana. It's definetly healthier in that respect.
