A 17-year-old girl overdosed Oct. 12 along Boone Hill Road, according to information provided by the department. Less than a gram of weed was found and tested positive for THC, the active component in pot, and fentanyl. The synthetic opioid is up to 50 times stronger than heroin and can be deadly even in small doses, according to the Centers for Disease Control and Prevention.

On Oct. 19, a 35-year-old man overdosed in Creekside Mobile Home Park. Police seized 130 grams of marijuana, which tested positive for THC as well as amphetamines, a synthetic stimulant.

Sgt. Dorothy Buchanan said both people survived. The man was given NARCAN, an emergency treatment for overdoses.

The drugs are being sent to State Law Enforcement Division for further testing. It is unclear yet how much of the synthetic drugs was laced into the weed; how it got there; or if those taking the drug knew it was tainted.

But Gary Lawrence, supervisory special agent at the Drug Enforcement Agency’s Charleston office, said they are regularly seeing drugs cut or laced with fentanyl, including cocaine.
