It has been reported as a novel designer drug in several countries including the United Kingdom,South Africa, New Zealand, the United States, and Australia. In 2018, N-ethylpentylone was the most common drug of the cathinone class to be identified in Drug Enforcement Administration seizures.
A doctor, David Caldicott, has said N-ethylpentylone "can cause circulation problems, lethal heart palpitations and hallucinations". It has been linked to a number of overdose deaths and mass-casualty incidents, and has increasingly been mis-sold as MDMA.
