I would err on the side of caution with this one. I know that anti-depressants and lsd don't go well together, so I'm assuming it's like that for most mind-altering substances.
In my experience anti-depressants made me violent. I didn't smoke much at the time but when I did, I did feel a bit off.
In reality anti-depressants only really act as a bandage, they don't actually fix the problems and usually bring new ones along with them. If you really want to stop your depression at the source I would recommend to cut back on the drugs and start working out. That's what I'm doing now and ever since I started working out I've felt about 10x better. Cured my depression way better than any anti-depressant did… Not trying to control your life just a friendly suggestion:D
