Czech police received reports on five online fentanyl sellers last year, with over 30 ads detected, drug regulators said. While fentanyl is legally prescribed for severe pain, some supplies leak into the black market. Police warn users extract it from pain patches. In 2023, officers seized 90 patches and 0.45g of fentanyl. The drug, fueling a crisis in the U.S., is also spreading in Europe.
