Ha Ha,
I've got the real 411. I'm 5'6" & 160lbs. I was forced to take weekly piss tests for 6 months (probate). I passed every one. My secret????? I researched heavily about MJ in your system. I even found a calc. from the point of totally clean, 1-Hit/High = 3 Days of dirty. I later pick up the jibber again toke once more....2-Hits/Highs = 6 Days of dirty and so on until 30-45 Days dirty depending on you.
I simple toked once a week after my test was complete and waited for next weeks test to smoke again. For 6 Months it worked like a charm. No dilution.
