Anecdotal evidence is nice, but give me scientific studies anyday! http://www.psychopharmacology.net/canbi.htm http://jop.sagepub.com/cgi/content/abstract/19/3/293 http://bipolar.researchtoday.net/archive/3/4/1247.htm

Try googling --cannabis abstract bipolar . You will get scientific studies for the most part. My mom was bipolar and wouldn't use cannabis. She used alcohol and eventually suicided. I have a touch of it, but I am fortunate enough to live in California and am medically "legal". Good luck!
