That's very silly. Weed doesn't turn people into habitual liars. Secondly, he was abusing drugs before that interview. Thirdly, he was telling absurd lies before that interview too. The hand wringing about him smoking a blunt is absurd, he doesn't have "reefer madness".
It's not the weed that fried his brain, it's the ketamine. That moment where he smoked up on camera seems to coincide pretty well with him losing his mind, though.
People get ketamine treatments for depression all the time. It's not drugs, he's just a nasty person who's been good at manipulating people in the past. People have just finally caught on to the con, at least in part because he's terminally online.
