im not positive but i dont think doctors even check for thc in there piss tests unless specificly requested and if requested there is a charge. thats what my mom told me atleast becuase she made me pay for drug tests out of my own money and i fraked out and i was like i'll just get a physical at the doctors, tell them i need one to go to camp or something. she called them and thats what they told her and the charge was gunna be more then it would just to buy a d-test.
