Not mariquana. Ephedrine may show up as met or speed.
Usually when I had to take RDT for my police job in the past, we had to fill out this form explaining every drug that we're either using or had used recently. I always stated that I was using something like Metabolift or Ripped Fuel w/ephedra, just in case.
I held that job for 11 years before quitting so I guess it never showed up.
