I don't have any idea. Whichever one they shove the swab inside your nose so far it tickles your brain. But knowing the VA, I wouldn't be surprised if they do both types of test. I always request a full drug screening and full STD screening every time I have a blood workup at the VA to be on record for security clearance reasons.

EDIT: Found a copy of my test results.
