Does shrooms show up in a mouth swab test?

Answer 1

Let me tell you all about mushrooms.

The active ingredient in magic mushrooms is Psilocybin. It looks NOTHING like any other drug, so it won't cross-react with one of the standard tests.

Mushrooms aren't a common drug, so unless you give your tester a reason to look for mushrooms--like you got busted with them, or you keep coming to work with fresh cow manure on your shoes when you live in an apartment (mushrooms grow on fresh cow manure), they're not going to pay to have you tested for them.

Besides, there's not enough time to really test someone for mushrooms. The halflife of psilocybin in your body is one hour. The halflife of the more-active psilocin is eight. (Psilocybin is a "prodrug"--when you eat mushrooms your body converts psilocybin to psilocin.) If you go to a mushroom party at 9pm, leave at midnight and get tested for mushrooms at 9am, you'll most likely be clean. So...why would they even want to test you? About all that test is good for is to back up a possession charge.

OTOH, mushrooms are a reasonably safe drug so long as you know what you're looking for when you go out to pick them. The therapeutic index--the ratio of effective dose to lethal dose--is 641. If you need to eat 1 gram of mushrooms to get high, you need to eat 641 grams to die from them.

Answer 2

Assuming you meant psychedelic psilocin/psilocybin mushrooms, I'll go ahead and say no, they absolutely do not. Most tryptamine psychedelics do not appear on drug tests. This is mainly because they aren't addictive, and they are processed and cleared from one's system pretty quickly so there really isn't a practical way to test for them.

Answer 3

No. As far as I know, there are no swab tests for shrooms. The chemicals involved are so powerful, and the amounts needed to trip are so minuscule, that it is unlikely that an emission spectrometer could identify them from a swab. It might be possible to construct a test that would react to something else in the sample, but Psilocybin is so seldom used any more that it would hardly be worth the trouble and expense. That doesn't mean that using them is smart; just that you can probably get away with it.
