That's all nice and well, but he also
did say "psychiatric drugs", as if those were somehow generally bad and appropriate to reference in the same breath as illegal drugs.
Maybe, had he not said that bit as well, I'd agree with you. He could be talking about Adderall purely in a sense of misuse.
But he included psychiatric drugs, and that (and the SSRIs) makes his statement ambiguous enough that I'm comfortable interpreting it as including ADHD patients.
(And, just purely for vilifying psychiatric drugs, the threshold for intolerance [which must not be tolerated in order to achieve a tolerant society] is crossed. Lots of people have mental health issues and need treatment, including with drugs.)
