I mean, depending on the drugs, this is not necessarily the worst idea. Sending acid tabs seems pretty concealable, and the spores of psychedelic mushrooms are not illegal to purchase. You could probably even send pills, if you put them in a hard candy/breath mint container as part of a larger and innocuous care package.

Like, it’s definitely better not to risk it, but this could be done in a discreet manner. I’m guessing he got poorly sealed and smelly weed though.
