i have a buddy that passed a weekly probation drug test while smoking a quarter a week, using this method i came up with:
the best way to pass a drug test is to dilute your urine by drinking a lot of water. this will cause the THC metabolites in your urine to be present at such a low concentration that they will not trigger a positive reading on the testing device. however, drug testers are aware of this trick, and have ways to check for dilution. a "diluted" result is either an immediate fail, or a re-test.
the first check for dilution is a merely visual test -- if the urine is too clear/not yellow enough, then it gets flagged for chemical testing. there is an easy way to get past this step, though -- B vitamins will color your urine bright yellow no matter how much water you've drank. you can drink two gallons of water, take a mega B complex pill or drink an energy drink, and your piss will still be yellow. often times, this is enough to pass a drug test, and you won't even have to worry about the next step.
however, if your sample DOES get flagged for further testing, the lab will test your urine for the presence of a substance called "creatinine." this is different but similar to the "creatine" that people take as a workout supplement. your body naturally produces its own creatinine, and there is a well established normal range of concentration of creatinine in your urine. if you drink too much water, the relative levels of creatinine in your urine goes down, and your sample will be flagged as diliuted. HOWEVER, your creatinine levels in your urine spike by an order of magnitude or two in the few hours after orgasming. so, well, yeah, you know what to do.
SO
1. drink tons of water (like 1-2 gallons)
2. take a B vitamin
3. rub one out
and you should produce a diluted sample that will still make it through the lab unsuspected.
other tips:
- don't work out or do anything that will cause your body to burn fat. THC metabolites are stored in your fat, so working out before your test will cause the concentration to go up.
- don't give them your first piss of the day. your first pee of the day is always danker, since junk from your system has all night to settle into your bladder.
- supposedly the first burst from your pee stream is more concentrated. IDK if this is true, but its probably worth peeing a bit in the toilet before peeing into the cup.
