Marijuana for curing headache I am having migraine for almost ten years. I had it since I was thirteen years old. I will have 2 to 3 migraine headaches in a week. They will last for about 48 hours. Throughout the years, I saw several doctors to find a solution to my headaches. They all talked about giving temporary relief to the pain by masking the pain and triggers. They never bothered to discover the cause. So, I continued using the same old medicines. The frequency and intensity of the pain are increasing every day. I feel tired of trying several useless medicines. My friend asked me to try medical marijuana cannabis from Toronto. I feel interested as this is an alternative form of treatment. Is marijuana effective in treating headaches? Is there anybody over here who has tried this treatment for treating headaches? Was it effective?
