I smoked marijuana nearly everyday for 10 years and was totally out of control and unable to stop. I had tried to quit dozens of times before and nothing worked, I was completely helpless. Then I went to an Ayahuasca ceremony last year and haven't smoked since, haven't even had the desire, and believe me, it used to be all I thought about. I can truly say that Ayahuasca saved my life, or at least returned quality to the shadow of a life I had been living. I'm not alone having this kind of experience. I would highly recommend doing some research on the topic, maybe it can help you too.
