You can be an idiot tweaker gacked out of your head as well as a racist white supremacist with a dumb idea about how to try to start civil unrest.

There's actually a long history of Nazis being on drugs. Hitler was thwacked out of his skull on a cocktail of amphetamines most of the time, and many/most of his filmed speeches show signs of extreme agitation that he was abusing stims, because, well, he was.
