i have a good friend in Colorado who, after years of surgeries and prescriptions, finally got his med card and started using Cannabis to treat his Crohn's disease. Took over a year to get off the Oxy-dose and fentanyl. He said the withdrawal was horrific.After that, he was only eating and smoking cannabis, taking a vitamin shot and a Humira shot. After 4 years, his Crohn's was in remission. 2 years after getting off the narc's, he went ona 2 week long hiking trip through Yellowstone park with both of his dogs. This is somethign he would have never been able to do before being a narc'd out zombie. Cannabis truly saved his life.
