Dr. Drug Dealer

This episode of American Greed tells the chilling true story of Dr. Lisa Singh, a Los Angeles physician who operated a high-volume pill mill disguised as a medical clinic. Over several years, Singh prescribed thousands of powerful narcotics—OxyContin, Xanax, Soma, and methadone—often for cash and without legitimate medical justification. Her patients, many of whom were healthy young men, were routinely given the 'Holy Trinity' of addictive drugs, a lethal combination that led to multiple overdoses. Despite growing evidence of deaths linked to her prescriptions, Singh continued her practices, showing no remorse. The case gained national attention after the death of 21-year-old Arizona State University student Joey Rivero, whose mother, April Rivero, became a fierce advocate against prescription drug abuse. After a landmark trial, Singh became the first U.S. doctor convicted of second-degree murder for recklessly overprescribing drugs, sentenced to 30 years to life. The episode underscores the devastating human cost of medical malpractice and the systemic failures that allow such exploitation to persist.
