Well the tests that have been passed from the Sure Jell and lots and lots of water/and gater aid are proof. This is fact.I know this to be absolutly truth. You can say otherwise but I know ...but anyhoo I dont have to pass any drug test so I really dont give a hoot. Best thing to do is just stop and be an adult and give yourself a good month to 3 weeks and drink lots of water. Thats the plan that gives you a clean test.
