Law enforcement officials from Ohio and Kentucky set up the "US Route 23 Drug Taskforce" in 1996 to patrol the highway for drug trafficking, attempting to halt a major artery of drug networks bringing high-quality cannabis grown in Kentucky north for distribution in Ohio and elsewhere. Lately, it has been primarily used to stop the flow of narcotics from large cities like Columbus, OH, Dayton, OH, and Cleveland, OH into Portsmouth, OH, all of which have to pass through US 23 to reach Portsmouth. Signs can be spotted along Route 23 in Ohio from Portsmouth to Columbus warning traffickers that efforts have been taken to prevent their actions. Some random police stings have been set up at portions of the highway.
