Rob Kardashian’s problems are far worse than having to drop a few pounds.

In the new issue of In Touch, a close pal of the reality star makes the shocking claim that the 27-year-old has been self-medicating for many months with powerful prescription painkillers. The friend alleges to the mag that Rob is using Norco and Percocet, as well as the antianxiety drug Xanax.

According to the friend, in the weeks leading up to sister Kim’s May 24 wedding, Rob was holed up inside his Sherman Oaks, California, condo “doing heavy drugs.” The source exclusively tells In Touch: “He’d just lie around his place smoking weed, doing drugs, watching movies and eating. He said he ‘needed’ the pills.”

Rob has also been indulging in “Lean,” the friend alleges to In Touch. Also known as “Sizzurp,” the highly addictive cocktail of prescription-strength cough syrup, Sprite and a Jolly Rancher candy can cause seizures and even death.
