This isn't scandalous as much as it is weird. Kevin Durant tweeted a photo of himself smoking—from what seems to be a hookah—before quickly deleting it and claiming his phone was hacked. Hookah's legal. (One can obviously pack other, non-NBA-approved things into a hookah, but there's no proof of that.) What's the deal?
It's possible that Durant was hacked, though athletes use that dumb excuse all the time when they do something they shouldn't. Either way, this whole ordeal is just odd.
Update: Nick Collison, Durant's teammate, says that Durant didn't tweet that out. So, he may actually have been hacked.
