Opioid drug overdose deaths are down in US, study finds, but COVID-19 could change that. DETROIT – McLaren Health Care Corp. has agreed to pay the federal government more than $7.7 million to resolve alleged violations of provisions of the Controlled Substances Act. McLaren said a pharmacist at its Port Huron retail pharmacy was “diverting opioids for his own personal use” and has since been fired. McLaren said it exited the retail pharmacy business in 2018, adding that the move was unrelated to the federal investigation. The health system has more than a dozen hospitals across Michigan.
