Salvia Divinorum: Show up in urine drug tests?

My wife found out we’re growing a LEGAL hallucinogen in our backyard, and I was wondering if it would show up in a urine-based drug test administered by the Navy. I’m not taking it if it’s keeping me out, and I thought I would be absolutely sure before I tried something.
I figure it’s legal, so usually there wouldn’t be a problem, but the Navy won’t let you in with something as small as ingrown toenails.
