I know a dude that trained with him and went out with those dudes a couple days and said he parties like no other. Which shouldn't be surprising. he got so much paper so young. This guy did an anti drinking and driving commercial and got a DUI right after. This shouldn't surprise anyone.
I'm honestly not that bothered by it. If he wasn't high during the fight, I don't think it matters, and even then. I don't think it would've impacted the fight.
If he truly feels he has a problem and isn't just doing it for the PR, then as someone who has had some issues with a few vices myself, I wish him the best on cleaning up.
Pretty much my feelings on it as well. Speaking as someone who worked on Wall Street for 5 years, I knew plenty of people who were in major positions of power and prestige who were using coke recreationally. It is what it is. There's drug use and abuse, if he feels he's spiralling out of control I wish him the best on his recovery.
