State officials have issued a warning about a heroin like drug that has caused 50 deaths in Pennsylvania already this year, including four in Berks County.
Berks District Attorney John T. Adams confirmed Thursday that toxicology reports have shown that four overdose deaths reported earlier this month all involved the drug fentanyl.
The state Department of Drug and Alcohol Programs said Thursday that fentanyl and its derivative, acetyl fentanyl, has been blamed for at least 50 deaths in 15 counties. Five nonfatal overdoses also have been reported.
The state also is awaiting toxicology reports from overdose deaths in several other counties.
