I took methadone once a week (60mg.-80mg.) probably 4 or 5 times. Would 3 weeks of not taking anything at all be enough time to pass a drug screen for methadone? Prior to the 4 or 5 times of once a week methadone I was clean for 7 months. I know methadone can stay in your system for a while, especially if you take it everyday for long periods. Thank You for anyone's info.
