What’s the best was to beat a drug test??? Find someone who is drug free and sort of looks like you and get them to be your impersonator.
We had this happen at our clinic, a mother came in impersonating her daughter. They were quite clever and had somehow electronically placed the mother’s picture on the driver’s license of the daughter. I’m not sure how they did that but the license looked real. The collection was proceeding normally but our collector had a 6th sense that something was just not right, particularly when he wrote the birthdate of the donor of the lab chain. That’s when it hit him that something was afoul.
