DON'T use bleach! Unless you know for SURE it is a home test. If they send it to the lab it will fail the pH test and you will fail the test.

The best advice I can give you is to keep your metabolism up, and smoke on fridays after school. Then you got 2 whole days to get it out, drink lots of water too.

It would help if you could find out what time they tested. That way you could just not smoke for a week or two before the testing.
Frivolous248 Reviewed by Frivolous248 on . In School Random Drug Testing.. what do you think? First id like to say that i am 6'3" and 180 lbs and eat all i can get my hands on (high metabolism) That being said: i go to school where they do random drug tests for all people in sports and anyone who drives to school (i apply to both of those). im a senior right now and over the years ive only been tested once (i was clean) and i know many many people who have never been tested. They do about 5 per week at a school of 3100. Ive heard people on here say that niacin works but is detectable Rating: 5
