Jasveen Sangha, known as the 'Ketamine Queen', was sentenced to 15 years in prison for her role in the death of actor Matthew Perry, who died from ketamine use. Perry struggled with addiction for years and was found unresponsive in his hot tub. The investigation revealed a network of suppliers, including doctors who profited from Perry's addiction. Sangha sold ketamine to Perry's assistant, who administered it to him. Following Perry's death, Sangha attempted to destroy evidence.
