What kind of drug test is currently administered in top secret security clearance positions in the foreign service?

Is it a urine analysis or a hair follicle test?

Does it really matter?


Never heard of any government agency using anything but the good old pee-in-the-cup but who knows.

apparently… draw your own conclusions

What kind?

The kind that detects drugs. All you need to know.

Curiosity finally got me and I found this:

As of the beginning of 2021 hair testing is not allowed for DOT testing or Federal workplace drug testing.

Is it bad form to reply to your own post?
