Narcotics for elephants and rhinos: Life-threatening drug seized in Munich. Carfentanyl has a pain-relieving effect that is 7,500 times stronger than the powerful painkiller morphine.

An overdose can lead to numerous dramatic side effects, including respiratory depression. Dozens of deaths have already been registered so far, including in countries such as Sweden, Belgium and Estonia. The Munich police expressly warn against the use of the drug, which has been seized more and more frequently in Europe in recent years.
