420:RSX

I been smoking for nearly 5 years straight with maybe a total of 50 days that i didnt smoke in those 5 years.I have been smoking for a year straight and I had an interview at a dealership. They told me I got the job as long as I would pass. Well I did....But im skeptical.I didnt stop smoking before the test date cuz I had less than two days notice so I figured I was f***** anyway so i smoked he afternoon before and day before that and so on so i really didnt do the 2 day sobreity. I went purchased the Vale 4x for 200lbs and over. I drank alot of water close to 9 glasses before i went to bed. Woke up the next morning pissed and drank three more...then at 8:30 started drinking the Vale...threw up after half the bottle...drank some water and took my time with the other half...didnt throw that up. Filled the empty bottle...drank it...pissed...filled it...pissed...drank it...pissed and filled it again before leaving. Get to the dealership piss in the lot... Go in and they have me waiting for like 30 min to fill out some paperwork so i had to piss again... got my dt paperwork and head for the clinic...pissed again in the lot before i drove off. Get to the clinic piss in the cup.All were clear except for a faint line next to THC...not too faint to say it was not there cuz i could see it perfectly...i thought i failed but they called me today and tell me im good to go and well i got the job. Dunno wat saved me or wat i did right but prior to the test i did smoke everyday 3-5 blunts,bowls,ect a day.Is this even possible?
