A Lexington psychiatrist has been found guilty of an international money laundering operation involving illegal drug imports, according to federal prosecutors. Dr. Rahim Shafa, 66, was convicted after a 14-day jury trial for his role in a sprawling scheme to purchase and implant non-FDA-approved drug implants into patients, the Justice Department reported. Shafa owned and operated Novel Psychopharmacology, where he illegally imported naltrexone and disulfiram pellet implants, used to treat alcohol and opioid dependence. These implants, sourced from Hong Kong, are not approved in the U.S., posing significant risks to patients’ health.
