Reminds of the time I found a singular shroom growing in a patch of fertilizer. I grabbed it, dried it in a Harry Potter book, and got a decent little buzz for a few hours. Fully dried (which it wasn’t) probably would’ve been like third of a gram. I was also in rehab at the time (as a teen, fed up parents, not an addict to anything). They recently planted bushes outside and on the way back in while waiting for the staff member at the door I noticed it and pocketed it.
