clean for 4 weeks? If u passed an at home test, take another one, or you can probably send it to the lab anyway and have results in about a week. Most of at home sellers will confirm with GC/MS free of add'l charge. Then you will kno for sure.
ToKnoIsToGro Reviewed by ToKnoIsToGro on . So, I passed my at home drug test..... and i haven't smoked anything for 4 weeks. I have a new job that i can start now or I can wait a couple of weeks. Question is, should I still wait to be sure or go ahead and start and take my test since I already passed an at home this week and last. Any advice? Rating: 5
