Is this for a job?
Usually they have a 5 screen test, in which mushrooms are not tested for. Even if they have a 10 screen, I don't think that is on there either. The big ones they test for are THC, Opiates,
Cocaine,
Methamphetamine, Benzos on the 5 panel. On the 10 panel they add PCP, barbituates,
amphetamine and one other I can't rememebr. But not mushrooms. I think you are safe.
