Smoke in general will damage any plant, marijuana smoke, tobacco, ANY smoke.

That doesn't mean 1 joint in your grow area will affect them much if any, but continue the habit, especially in a NON-ventilated room, and your plants will suffer. They will not be kind in return when harvest time comes around.
