I've been drug tested countless times by different tests, companies, and reasons and have never failed one to date. I was baked the whole time. The trick is to get someone about your age and sex who is clean to piss in to a bottle for you. Then transfer some of it into a small squirt bottle (like a visine bottle). Get some tighty whiteys and place the bottle under your balls to keep it warm. Now just pretend to piss but use the squirt bottle. This even works if they are watching you piss, you just gotta be careful and smooth about it. Worked for me at least 40+ times. Good luck!
