Is smoking marijuana bad while on accutane? How about drinking alcohol?

Don't do it. When you started up on accutane, you probably made a promise not to drink alcohol while you're taking it, to be good to your liver. You'd do well to keep this promise. Congratulations on your courage to take this medicine and clear your acne. It's a brave start to a new life. Why go into it goofy from smoking "weed" -- even if it's legal where you live?
Smoking marijuana . Is just plain bad for you. If you are concerned about your health enough to ask this question, you are concerned enough not to injure it with smoke. Please consider.
