Question

Does evidence of taking magic mushrooms appear on a CAT scan or MRI? If so, how long will it appear for?

Answer 1

Knowing nothing about how the scans work, my gut feeling is this: if you are no longer feeling the effects, it shouldn't show up on a scan.  Bloodwork is probably a different story.

Answer 2

No it will not.  I would say if you are going in for a scan on your brain don't take mushrooms before going in because that will tamper with the scan. They wont know you're on shrooms, but they will know somethings going on.
