This is going from bad to worse!

Lamar Odom has been battling drug addiction for the past several years, but the former basketball player's problem has gotten even scarier, because he's now experimenting with a dangerous new drug combination called "sherm."

"He has been doing an old-school drug called sherm, which is taking a joint and dipping it in liquid PCP. It’s really dangerous and can make you violent," a source revealed to In Touch.

Estranged wife Khloe Kardashian, who filed for divorce from the former Laker in December 2013, is worried sick about her soon-to-be ex hubby's substance issues. “Lamar’s friends and family and Khloé are all pushing him to get into rehab. Lamar needs serious, serious help,” the insider added.

Please get help, Lammy, because we love you and want you to get better!
