Authorities in Mexico raided several Los Cabos drugstores last month and arrested four people as part of an ongoing investigation into pharmacies selling counterfeit pills laced with fentanyl and methamphetamine.
In total, authorities confiscated nearly 25,000 pills in the raids. None of them tested positive for fentanyl or methamphetamine, but came back as other controlled substances that the pharmacies did not have authorization to sell.
