The medical properties of marijuana have already been proven by scientists. I know a lot of cases when marijuana helped as with asthma, arthritis, ADHD, autism. But quite recently, I discovered marijuana for migraines. I struggled with this problem for a long time, tried a lot of different medicines. And now accidentally I found an article on this site about marijuana and permanent migraines and decided to try. Honestly, the effect was better than I expected. But the result wasn't so bad, I'll try more. Thanks for the helpful link.
