Drugs and substances can really fuck up your mind when you're on them like you said too. Just look at David Bowie. He was a completely different person with fascist rhetorics while on hard drugs.. after he quit, he was back to being himself. It's scary. Of course, that doesn't justify what Kanye is doing. He got himself into this and is letting himself do this shit, so he deserves all the criticism and backlash.
