Hi there, I too take Zanax, and I also take 200 mg Lustral anti-depressant every day. For me, it all works well, i find I suffer lack of appetitie with the Chemicals, so the Marijuana, allows me to eat. Nothing cancels out nothing, for me they al work well together. My doctor is also aware, and whilst she would never say, ' way to go', she dosent dissparove either.
Id rather use marijuana all the time though, instead of chemicals. I find the Zanax, leaves a sick feeling.
Withoug marijuana Id be dead from weight loss i think.

Good luck to you,
