well... i have LOTs of personal experience from being on probation for several years..threw rehab.. threw placements.. now on parole. i have only failed one drug test. whice is the first one they ever gave me.

Now telling you po thatthc might be in your system because youve been around it might be a better option than admitting to smoking but realize it is a violation to be in the presence of someone smoking or in posession of marijuana.

Know that the simple strip urine tests are very inacurate but work enough to bust you. there are several ways to mask you urine.. you cant clean ur syetem perminatly only tempoarily. Ive gone to gnc and purchased the detox. Your not suppose to smoke for atleast 3 days before using to insure ur chances of passing but i smoked the day before liek always and passed. its exspencive but might be worth it. usually i just drink LOTS of water. Some people may say it doesnt work but believe me i smoke everyday constantly up to the day i report then i get all paranoid and drink water all day.
the key is to piss as many times as possible before you report. you dont have to start a weeek b4 u report. i usually start the night b4 i report. i drink alot of water b4 sleep, wake up in the middle of the night, drink more, sleep, Repeat. then the next day i have a big cup with water and drink whenever i think i can hold more water. now when u piss its gonna come out clear. your po might say somthing about it. a way to make ur piss yellow is taking vitamin c pill or vitamin b12 pills anything like gatorade. azo's dont do anything but help u piss alot. theese make ur piss red, orange, then yellow if u take theese a few days b4 u repot the color should be a nice consistant yellow dont take too near ur report date because it will be obvious when u piss red or dark orange. hope this helps

oh, and as far as the ''thc level'' its probobly bullshit. just know it takes 30 days to get out of ur system and if it hasnt been that long he cant lock u up for that. he would probly have to send it to a lab somewhere to be tested for the level.
