Human Abuse Potential & Abuse Liability

The opioid crisis has had devastating consequences of drug abuse that has become widely recognized. As many as 841,000 people have died from a drug overdose between 1999 and 2019.[i] This increased awareness has led to strict regulatory guidance for the assessment of Human Abuse Potential (HAP) of novel drugs.
