when did u start smoking and how long did u smoke heavly?? because i have to take test every week and i thought i smoked alot but when i took my 1st test it came up low (they have a scale high medium and low) and i smoke like 3-4 times a day bowls/bongs/joints/volcanos and it took like 3 weeks to clear outa my system. so since ur 36 id imagine uve been smoking a while and probally pretty heavily so it may take a while to clear outa ur system. but i have absoutly no clue thats just me using my logic lol. and also i think if u fail the test i believe you have to pay for it?????? im 100% sure but my friend failed one for a job and he had to pay for it......any ways good luck with the test and the new jobrasta:
