A rash of heroin overdoses reported in the last two weeks in Kentucky, Indiana, Ohio and West Virginia, has officials concerned the drugs came from the same batch, “likely mixed with either fentanyl or carfentanil,” Harrison Jacobs reports for Business Insider.
Fentanyl, a synthetic opioid, “is 80 to 100 times as powerful as morphine and about 40 to 50 times as potent as pure heroin.”
Carfentanil, frequently used as an elephant tranquilizer, “is 100 times as potent as fentanyl, which makes it roughly 10,000 times as strong as morphine.”
