MMJ is not a cure all medicine for depression, PTSD, et al., and is not for everyone.
That being said, they (the powers that be) SHOULD make it legal for medical reasons because a lot of people gain benefit from it, from pain management to PTSD symptom abatement to insomnia to muscle spasms, and it carries with it far fewer side effects compared to meds from Big Pharma.
I am currently living in a state that still has fascist policies against MMJ, yet I still use.. because if I didn't I would be thinking is blowing my brainses out day in day out just to stop the suffering from PTSD. I'm working on moving to Colorado, though.
