Joj, you are posting in the wrong thread. You should have started your own thread and asked your question there because Brandon hasn't been on since May 2006 and it really is off topic for a general discussion on drug testing.

The guideline is 3 times getting high in 90 days if the hair length is 1 and 1/2 inches. Your one brownie should not cause you to fail. In the future I prefer Zydot but Biowash is ok but much more expensive. Use it the day of the test and you should pass. If you have any more questions please start a new thread.
