Will there be a drug test in my 1st, 2nd, or 3rd class medical exam?

No. The FAA does not require AMEs to conduct drug tests on individuals seeking or renewing a medical certificate. The exam does include a urine analysis. This is to check for sugar and protein levels, which can indicate diabetes or kidney disease.

That said, you’re required by law to disclose any drug use on your medical application. Furthermore, most companies that employ pilots are federally required to implement a drug testing program.
