How did this happen??!

K Im a senior at my school and our school randomly drug tests ( private ) , they usually test like 4 times a a semester but this year they havent done it once.

I've quit toking but started back up last week...smoked pretty every day for a week and got tested 10 hours after my last bowl. I passed my test, I don't understand how this happened this is the second time also..my parents did it to me a few months ago and I somehow passed..each time knowing I'd get shit for failing, the are also sent to a lab pretty expensive shit



ps i know how to inhale

is this a trick question? you didn't take niacin or anything like that? i've never had to take a drug test, but i imagine i'd have to do something to clear my system. the only answer i can come up with is you piss a lot. maybe your an active person? i don't know. nonetheless, i do know your a lucky person, well, lucky enough to have ignorant parents.
