Charlie Sheen is drawn into the investigation into the Matthew Perry drug ring

Federal prosecutors say Sangha ran a “drug sales emporium” for years from her North Hollywood home in Los Angeles — distributing ketamine, cocaine, methamphetamine, Xanax and other narcotics, court documents show.

She now faces a life sentence on a series of federal drug charges and is also linked to Perla Ferrar Hudson, the ex-wife of Guns N’ Roses guitarist Slash.

Hudson, 49, shared a video to her Instagram featuring a series of photos of the couple on their many vacations and detox sessions — and she called the alleged drug deal a “sister sent from God.”

Like Sheen and Perry, Mueller has battled a series of substance abuse problems over the years and in July 2011 entered a drug rehabilitation program.

Two years later, her children were removed from her home due to suspected drug use and Mueller entered rehab again at the time.

She is also said to be close friends with 54-year-old drug dealer Erik Fleming, who pleaded guilty to two charges and admitted to being the one who supplied Perry with the ketamine that ultimately killed him.
