Now if I went back to the military(god knows why), they would see my record and know I smoked weed. But the regular world never knows. So my major weed bust is only in my military records. If I ran for president, they would find it, but Im not worried. I have read all sorts of nonsense on drinking volatile liquids, taking pills and garbage to cover up a piss test, but you nailed it on the head. Abstinace is the only thing that works 100%. If you want to be COMPLETELY sure you pass a drug test, abstain for a month(if you can). After the test, go back to being regular, lol.
