Biomedical plants and industrial chemical parks to be probed

Police will conduct a thorough investigation into biomedical plants and industrial chemical parks in some key areas, according to the Ministry of Public Security.

The probe is aimed at stopping the production of substances related to the drug fentanyl.

The synthetic opioid, which is 50 times more powerful than heroin and 100 times more potent than morphine, is prescribed to treat patients with chronic pain, especially after surgery.
