Sorry, I perceived it as relevant to the first sentence you said.

Absolutely - my SO is diagnosed and I've been with her in the pharmacy where she was blatantly accused of trying to get it so she could sell it (nope, just a normal college student diagnosed with ADHD). That was wild.
I think they thought she was taking me along because she was going to sell to me after? It was unclear, but they were definitely suspicious of my presence.
