Revisiting the 'paradigm shift' in opioid use: Developments and implications 10 years later

Area of Science:

• Public Health
• Substance Use Disorders
• Pharmacology

Background:

• A decade ago, a shift from heroin to prescription opioids (PO) was observed in North America.
• Prescription opioid misuse is now a severe public health crisis, affecting life expectancy.
• Medical system practices are recognized as key drivers of the crisis, yet policy interventions remain limited.

Purpose of the Study:

• To revisit and analyze the 'paradigm shift' in opioid use in North America 10 years later.
• To assess the ongoing impact of prescription opioid misuse on public health.
• To identify policy challenges and lessons learned from the evolving opioid crisis.

Main Methods:

• Review and analysis of trends in prescription opioid and heroin use in North America.
• Examination of the role of medical system dispensing in the opioid crisis.
• Assessment of existing and needed policy measures for addressing opioid misuse and harms.

Main Results:

• Prescription opioid misuse, morbidity, and mortality have escalated, becoming a major public health crisis.
• Heroin use is increasing again, often following initial prescription opioid use.
• Policy faces dual challenges: reducing medical prescribing and supporting active problematic users.

Conclusions:

• The North American opioid crisis, driven significantly by medical system practices, presents complex policy challenges.
• Urgent policy is needed to reduce prescription opioid misuse while providing harm reduction and treatment for existing users.
• Lessons from this crisis are crucial for informing future drug policy and public health strategies.
