| Two deadly drugs behind an epidemic of fatalities in the US are now spreading onto British streets, the UK’s National Crime Agency (NCA) has warned.
Police believe a spate of deaths in the north of England has been caused by heroin laced with fentanyl and carfentanil. Public Health England has issued a drugs alert in a sign of how concerned police and medical authorities are becoming. Four people died in the Barnsley area of South Yorkshire, on April 14 and two men died the day after in Leeds and Normanton in West Yorkshire. Since these six deaths, there have been similar fatalities recorded by Humberside and Cleveland Police. |
 | On Tuesday, public health officials confirmed the first cases of overdose deaths from carfentanil in New Hampshire. |  |
 | Maryland officials said that three people have died of overdoses of the synthetic drug carfentanil. One day after announcing Wisconsin's first death attributed to carfentanil the county's medical examiner said the drug is to blame for two more deaths in Milwaukee. In Illinois carfentanil has killed two in Sangamon County in the past two weeks. Carfentanil was found near the scene of a pair of fatal drug overdoses in Colorado. In Minnesota authorities said that carfentanil is to blame for five recent overdose deaths. In South Carolina another two deaths have recently been confirmed. |  |
 | Throughout the U.S., carfentanil is being found in cocaine, counterfeit pills, methamphetamine, heroin and other drugs. It can also be found in liquid form. The situation is the same in Canada. Carfentanil was seized during a drug bust in Hinton. Inmates have been overdosing at Drumheller Institution from carfentanil. Carfentanil has been detected in Port Alberni and the Alberni Valley. It has appeared in drugs seized north of Toronto in Richmond Hill. |  |
 | Last September, the U.S. Drug Enforcement Agency issued a warning to law enforcement about carfentanil. Those warnings are proving frighteningly accurate. Carfentanil is 100 times deadlier than fentanyl, which is 50 times deadlier than heroin. |  |
