List of Opioids Strongest To Weakest
Carfentanil is a painkiller and analgesic used on large animals such as elephants and is 10,000 times stronger than morphine. As such, it is not intended for use in humans, as there is no known safe dosage. In recent years, carfentanil, which is likely illicitly produced, has been used as a buffering agent in heroin and other drugs. As a result, it has been responsible for hundreds of deaths in the U.S. Just two milligrams of carfentanil is enough to sedate an elephant. Moreover, law enforcement and first responders have been warned that if bare skin touches even a small amount of carfentanil, severe effects may occur, including death.
