Is there any evidence Trump is on Adderall? Other than his erratic, occasionally manic behavior, which could be a sign of any upper.

I always figured he was abusing pseudoephedrine, since he had a drawer full of it in his first term.

I could also imagine him doing a kind of "Dr. Feelgood" mix of drugs just like Reagan and Hitler. He is following in their footsteps. This idea seems unlikely though, Trump appears to be somewhat of an honest teetotaler due to his family history of drug abuse and early death.
