Tried it before, with absolutely no success. Just got my card again recently, and tried a new delivery method, the vape method, like an e cigarette. 80% pure thc. It is not a miracle cure, but it has been of some relief. At least it helps stretch out the 10 norco pills I get per month to deal with Chronic Daily Migraine. My oldest brother only uses marijuana for his migraine control, but he was a smoker from high school, and I had never touched it until I tried it before for the migraines. Plus I have had many concussions from football. And now, at age 57, I am seeing some mental fog starting. Not much, but perhaps just due to getting older. I will keep it monitored, and if it worsens, I will get checked.
