Is it illegal to fake a drug test for employment?

Yes, it is illegal to fake a drug test for employment. Falsifying the results of a drug test could lead to legal action, fines, and potentially time in jail. The exact consequences of doing so vary state by state, as this is an issue that is handled at the state level.

In general, if your potential employer learns that you faked or cheated on a drug test, some sort of disciplinary action would occur. You most likely would not be in consideration for that new position. If you are already a current employer completing a routine drug test, it is highly likely that you could be put on leave or fired if you tamper with a drug test.
