well i used to be on felony ua (long story) for about 5 years so i took alot of UA's and i tried alot of different techniques. The way our ua's worked is we were on a color system, meaning you call in to this phone number and if your color is read you report the date stated for a ua. well i tried everything to get around them and alotta times didn't work. ended up by the nearing end of my probation i had to report monday through friday (5 ua's a week) and one DNA test every week. And what my probation officer said i could take up to 7 hit's of marijuana and still pass a ua. (cause i said i only took 3 hits when i failed a ua previously). I also tried the, "well my friends smoke and i was around them routine..." she said i'd have to literally put mouth 2 inches from their's and inhale every hit for a week straight to have the thc level higher than usual, in the body, leading to a failed ua. u should have no problem passing that ua. BUT to be sure, take 500mg niacin (dietary supplement that flushes the body, trust me you'll feel it and plenty of water on a daily basis and stop the niacin one week prior to UA so it will not show up in the ua (as minnesota government lab test trace niacin and mark it as a dilution method.) but you could also say that you use it for dieting since it is an over the counter pill. Hope any of this was useful. if you still feel uneasy, buy a $200.00 ua drink. (one's that say double your money back guarantee, WOULDN'T SAY IT FOR NO REASON)
