Hello everyone.... I have a question about the GC/MS drug test... I understand that the cut off level is 15mg
One friend wants to know about the chances of getting a positive result on a GC/MS test.. here's some info
-Daily user for 5 yeas (bowl almost every day he says)
-He has been clean for about 12 weeks
-He's tall and skinny so I'm supposing fast metabolism
I told him that the best way for testing negative is stop smoking..
So.. any chances on testing positive after 12 weeks on a GC/MS?
