Khloe Kardashian to Lamar: You Do Drugs Again, I'm Gone for Good

Khloe Kardashian isn't stupid, and she's ready to relaunch divorce proceedings if Lamar Odom shows any signs of going back to the world of drugs ... so say sources connected with Khloe.

Our sources say Khloe is annoyed by people on social media who are calling her naive for dropping the divorce. TMZ broke the story, Khloe and Lamar both signed off to dismiss the divorce case, which was all but final.

We're told Khloe knows better than anyone about Lamar's battle with drugs. Feelings aside, she's game to drop the divorce partly because Lamar has no one else in his life to help him recover. And, by the way, we're told Lamar is on the Kardashian health insurance policy and he needs to stay on.

Lamar's medical bills will total in the many millions, and our sources say he doesn't have the financial wherewithal to handle it on his own.

It's murky, because if this were just about health insurance, Khloe could easily buy it for him and go through with the divorce.

Bottom line ... if he goes back to drugs, she's gone.
