The global opioid use disorder market size was valued at USD 1.9 billion in 2018 and is anticipated to grow at a CAGR of 10.1% over the forecast period. An increase in the opioid epidemic in the U.S. coupled with the establishment of government policies to control the crisis is driving the market. Opioid Use Disorder (OUD) is a chronic condition associated with compulsive, prolonged, and repeated self-administration of opioids. There are two types of patients suffering from OUD: patients who are addicted to non-medical opioids and patients addicted to medical opioids. A single factor cannot be accounted for OUD, but a combination of environmental and genetic factors influences the patient.
