I know this might be

but he could have been doing lines of adderall. Either crushing IR or XR Adderall looks sketchy as fuck. But people do freak out and think someone’s “out of control” when they’re not eating pills, even though eating a fuckload of pills is horrid for your digestive tract.
He might be doing it to try and cope with the lack of appetite by getting the effects through snorting it vs. ingesting it.
You could make hour long compilations of Paul sniffling or snorting during streams especially when he first gets on streams for Reddit recap.
Aside from damaging your nose / sinuses, he’s not at more risk of hurting himself than he is taking Adderall against prescription guidelines and watched by a medical professional.
My point is: there is so much false information, memes, Paul’s lying, Paul’s bragging, unreliable characters, and drama whores around him to where we can’t know the truth even if Ice talks about it.
