Background: I'm 26. Before I was self employed, I worked 22 jobs (no, im not exaggerating). I walked out on many jobs just to start another one the next week, so I became very familiar with drug testing. More than half of those jobs drug tested. I worked in all kinds of jobs from Burger King to the U.S. Postal Service to Microsoft. I never failed a drug test on any of the jobs that tested. I'm naturally skinny, which helps, but I've always used the methods in this guide and passed and if I didn't have a week or two to quit and get clean before the test, I would just use synthetic urine which I had to do twice and passed both times without any problems. When I first became self employed and was bored at home, I decided to test all these methods on home tests I purchased just to see if it was luck or not and passed them all as long as I had a few days or a week to follow the methods.
