NH police warning of potentially lethal batches of heroin featuring new drug, W-18

NH1 Digital Content Manager -

Police just across the N.H. border are warning about an extremely potent opioid that could be deadly.

READ: New drug to North America is 10,000 times stronger than morphine

The Sanford Maine Police Department and the Wells Maine Police Department both issued warnings over the weekend on their Facebook pages.

Plaistow and Bristol police have also taken to Facebook to warn about the synthetic opioid, called W-18 - the most powerful series of about 30 compounds.

Experts say that it is 100 times more potent than fentanyl and 10,000 times stronger than morphine.

More than 2.5 pounds of it was found in the home of a Florida man who was then sentenced to 10 years in federal prison.

Police said the powder is getting mixed with heroin.

Health officials are concerned because current drug tests cannot detect the drug in a person's blood or urine which will make it difficult for doctors to help someone who may be overdosing.
