It depends mostly on your body weight and metabolism. If you have a fast metabolism you can get clean in under 20 days but if you have a slow metabolism it can take as long as 45 days. My nephew once had to drop and he had smoked 17 days before his test and tested clean. He is also really scrawny and has a fast metabolism. I on the other hand have a slower metabolism and weight 160 Lbs. I had a urine test; so, I stopped smoking 40 days in advanced and still dropped dirty. It goes to show ya. You never quite know. It's best to judge it yourself by weight and metabolism then some chart that is universal for everyone because that chart doesn't exists.
