People smoke weed to get high, that's the way it should be.
Most of the medical benefits of marijuana come from the high it gives you and how it changes your perception, distracting from pain and other anxious worries.
For me, I used to have chronic stress migraines...at least one a month. Debilitating. Can't do shit and the pain was unbearable. Started smoking weed when I was 17 and never one again. I shit you not.
I know people with anxiety and stress and let me tell you, it works to ease that stress, that anxiety. When you smoke weed, you realize a lot of shit just doesn't matter. And in my uncertified opinion, the majority of pain is THINKING about pain.
I walk outside and it's cold...really cold. Goosebumps, chilled to the bone cold. Stop thinking about it. Now it doesn't effect me as much. See what I'm saying?
