Drugs were found in Lamar Odom's system after he was found unconscious at a Nevada brothel, E! News reports.

According to a source, Odom remains unconscious and his condition is being treated as an overdose. It's possible he also suffered an ischemic stroke, which is when a blood clot stops blood flow to the brain.

"So, likely there's brain damage, but they're not sure how much," the source said. "Virtually every drug imaginable was found in his system."

The insider went on to say that Odom had been doing excessive amounts of crack cocaine throughout the weekend and choked on his mucus.

After the former Laker was found unconscious Tuesday afternoon, his ex-wife Khloe Kardashian rushed to the Sunrise Hospital in Las Vegas where Odom is being treated.
