My parents are making me take a drug test at a hospital for marijuana. if it comes out positive that i do have THC in my system.....what happens after that?? do i get locked up? or do i get in trouble with the law or something??? the last time i smoked weed was monday, july 9, 2012 and i got caught by my parents and they said they were taking me for a drug test in a month. i dont know if they mean a drug test from the store or the real **** (hospital). so im trying to find out of awesome ways to get THC out of my system and how long it will take. im 5'5, 16 years old, im skinny, i work out and drink alot of water already and im about 128 pounds and im a male. If i do take the test from the hospital ,which i think i most likely am, i dont think im gonna have high security cause its not for a job or anything. BUT im willing to do anything to pass this test i smoke about a dub atleast once or twice every week and its never low-potent stuff its always decent to high potent weed.
