Question: when are you supposed to quit smoking on chantix?
Answer: Depending on your quit approach, your quit date could be a week or up to a month after starting CHANTIX. Or, if you're sure you're not willing or able to quit that abruptly, you start CHANTIX and then cut your smoking in half each month with the goal of quitting at the end of 12 weeks (3 months), or sooner.
