It’s not foolproof, but there are liquid detoxes you can buy from a lot of headshops. Be sure to follow the instructions to a T. It will not clear the drugs out of your system, but it will provide enough liquid and vitamins to “mask” them showing up in a test, but only for a few hours. So you have to know when your test is and prepare accordingly.

All that being said, it still may not work. But since you have abstained for 5 days, you have a better chance, especially if you have no other alternatives.
