Rob Kardashian's family is deeply concerned about him, and for reasons beyond the well-documented weight problem that's made all kinds of headlines.
Family insiders say Rob has developed a very bad drug problem.
We're not sure what's worse, these TMZ photos of a drug-fueled party attended by Rob a few days ago, or the fact that his family is reportedly not surprised.
He wasn't just a bystander there to hang with the boys, either.
In the scandalous photos, Rob is seen puffing smoke, passing what looks like a blunt and holding a double cup, the container of choice for Sizzurp.
The cup in one picture actually has "Codeine Boys" emblazoned on it, too (in purple, natch). Not so subtle, fellas ... although Justin Bieber would be proud.
According to reports, the Kardashians have been calling various rehab facilities, but Rob refuses to go. In fact, he's totally ignoring Kim and Khloe.
