I'm a diabetic who smokes, and i have alot of complications due to my lack of healthcare for years. Marijuana helps the chronic depression, it helps me eat (i have gastritis, and i just don't get the urge to eat sometimes, that or it makes me nauseous so i dont, it helps me sleep (insomnia). It really does help your metabolism though, you just have to avoid the urge for bad munchies lolz
