On Sunday, March 12, 2017 Long Island’s Newsday published an article entitled “Bracing for Deadly Drug to Hit LI”. Below is an excerpt from the article for your information. The emphasis was not part of the original statement.
"Carfentanil is 100 times stronger than fentanyl, the most powerful opiate available for use in medical treatment, Drug Enforcement Administration officials said. A single drop of the drug, which is used to tranquilize elephants and other large animals and is not intended for people, could be enough to kill drug users. It would also pose a threat to first responders rushing to save overdose victims because carfentanil can be absorbed through the skin and can be accidentally inhaled."
