My mom has arthritis, back pain, and almost daily migraines. She's tried all the pills the doctors said would help, none of them did anything for her. Medical marijuana is legal here, and I think it could help her. The problem is that she believes all the lies about it. She thinks it's a dangerous addictive gateway drug that causes cancer and kills brain cells. I think it's the only thing left that could help her, what can I do?
