Is talk therapy with a legitimate, certified therapist and marijuana a cure for depression?

I don't think marijuana is a cure for depression but other pharmaceuticals such as effexor, paxil, abilify (sp?) have not helped my depression. Talk therapy helps immensly. Talk therapy with a psychiatrist or therapist in conjunction with marijuana smoked in the morning helps me feel so much better. Can marijuana be viewed as another form of antidepressant and/or anti-anxiety meds.?
