if you dont smoke at all i heard it could be a week to 13 days and if you are a daily user it could be a month to 3 months depending on if you're fat or skinny. you can drink tons of water and exercise and sweat to quicken the process of detoxifying your body, maybe get a gym membership and sit in a sauna for a few hours. any way you want to sweat quickens the process of detoxing your body of all the toxins.
