I'm diagnosed as manic depressant, I've been on lithium for proably 6 or so years, and I have to be on lithium indefinately. I don't get many manic episodes much anymore, last one I had was proably 2 years ago. Lithium helps balance my moods, but then again lithium is a naturual element, not a drug really, The last almost 4 years I have been smoking pot and it doesn't affect my medication. But then again anti-depressants are a differnt storry all together. By nature MJ is classified as a depressant, but I think thas is too much of a generic classification based on some guys therioes who proably never even smoked weed at all. When i smoked it in Highschool, a few times it made my depression worse, one of the reasons why I stoped the useage of weed for a bit. But I think it depends on the person, but don't go off ,of your meds, that can be dangerous, certain medications you have to ween yourself off of them. Just be careful in your choices, I trully say if your happy the way things are working continue on that path.
