A Global Perspective on Opioid Consumption
The landscape of opioid consumption is not uniform and has shifted significantly over the years. Historically, the United States has been recognized as a top consumer, with data from 2009 showing it consumed roughly 30% of the world's opioids despite having less than 5% of the global population. However, by 2015-2017, Germany, Iceland, the United States, and Canada led the world in per capita consumption of controlled opioids, based on data from the International Narcotics Control Board (INCB). Global consumption volumes overall declined from 2009 to 2019, primarily driven by decreases in the US, Germany, and Canada.
Meanwhile, significant disparities in access to essential pain relief persist. High-income countries (HICs) exhibit dramatically higher opioid consumption rates compared to upper-middle-income (UMICs) and low-and-lower-middle-income countries (LMICs). Research from 2009-2019 shows that median consumption rates in HICs were substantially higher, while rates in UMICs and LMICs were much lower, and the opioid selection in these countries was more limited.
Shifting Trends in the United States
Within the United States, the dynamics of opioid use have evolved. The national opioid prescribing rate peaked around 2012 and has since decreased. However, this reduction in prescription volume has been overshadowed by a surge in illicit synthetic opioid use, primarily fentanyl, which is a major driver of overdose fatalities. The following demographic and socioeconomic factors illuminate who is most affected by this ongoing crisis.
Demographics of Opioid Overdose
- Age: The burden of overdose deaths is concentrated within specific age brackets. The 35- to 44-year-old age group has recently experienced the highest number of opioid overdose deaths, with significant increases noted in this demographic. High rates are also observed in the broader 25-54 age range. The CDC has also noted rising drug overdose death rates among adults aged 65 and older.
- Gender: Across most age groups, males account for a higher proportion of opioid-related overdose deaths than females. However, an increasing number of women, especially those of childbearing age, have developed opioid use disorder (OUD). Women may also be more susceptible to cravings and relapses.
- Race and Ethnicity: Persistent racial and ethnic disparities are evident in both prescription practices and overdose deaths. While White individuals have historically shown higher overall rates of prescription opioid consumption, studies indicate that Black and Hispanic patients are often prescribed fewer opioids for pain, reflecting significant healthcare inequities. Despite this, rates of drug overdose deaths have increased substantially among non-Hispanic Black and non-Hispanic American Indian or Alaska Native (AI/AN) persons. AI/AN populations have shown the highest rates of drug overdose deaths in both urban and rural counties.
The Role of Socioeconomic Factors and Geography
Lower socioeconomic status (SES) is consistently linked to a higher risk of long-term opioid use and overdose fatalities. Factors such as poverty, unemployment, and low educational attainment contribute to economic distress that often fuels drug misuse. For example, Medicaid enrollees with lower incomes are more likely to have frequent opioid prescriptions. Furthermore, studies have shown a higher prevalence of substance use in communities with worse economic conditions.
Comparison of Socioeconomic Risk Factors
| Risk Factor | Population | Risk Level | Details |
|---|---|---|---|
| Income | Low-income individuals and families | Higher | Individuals living in poverty or with low income have a higher risk of developing OUD and experiencing fatal overdose. |
| Employment | Unemployed individuals | Higher | Unemployment is associated with an elevated risk of fatal opioid overdose compared to employed individuals. |
| Disability Status | Disabled individuals | Higher | Those with a disability are at significantly greater risk of fatal opioid overdose, likely reflecting treatment for chronic pain. |
| Education | Less than a four-year college degree | Higher | Lower educational attainment is linked to an elevated risk of opioid overdose mortality. |
Geographical Consumption Patterns
Geographical variations in opioid use exist both internationally and within countries. In the US, opioid dispensing rates are highest in Southern states like Arkansas, Alabama, and Mississippi, while they are lowest in states like Hawaii and California. The West and Midwest have also been significantly impacted by the rise of illicit synthetic opioids. Data also indicates that rates of drug overdose deaths involving synthetic opioids (including fentanyl) are higher in urban counties than in rural counties. However, the rates of deaths involving psychostimulants and natural/semisynthetic opioids are higher in rural counties.
Broader Factors Influencing Opioid Consumption
Beyond simple demographics, a confluence of environmental, behavioral, and biological factors influence who becomes dependent on opioids.
Key Risk Factors for Opioid Use Disorder
- Duration of Prescription: Using opioid medication for more than a few days significantly increases the risk of long-term use and addiction.
- Mental and Behavioral Health: Individuals with mental health diagnoses such as depression, anxiety, and PTSD are at a higher risk of developing OUD. Behavioral indicators like a history of substance abuse or risk-taking behaviors are also influential.
- Social and Environmental Stress: Stressful home or work environments, homelessness, and experiencing adverse childhood events (ACEs) contribute to increased risk. The decline in economic opportunities and erosion of social capital in many communities have also been identified as root causes.
- Genetic Predisposition: Research suggests that genetic factors can increase an individual's susceptibility to substance use disorders, including OUD.
- Healthcare Access and Bias: Unequal access to pain management alternatives and persistent racial biases in prescribing practices exacerbate the issue, particularly for racial and ethnic minorities.
Conclusion
Determining who consumes the most opioids is a complex issue with no single answer, as consumption patterns vary widely across the globe and within populations. While high-income countries still account for the majority of prescription opioid consumption, the recent rise of illicit synthetic opioids has dramatically changed the landscape of overdose fatalities, particularly in the United States. In the US, young and middle-aged men from low-socioeconomic backgrounds and specific racial/ethnic groups, such as AI/AN individuals and Black men, bear a disproportionate burden of fatal overdose, while racial biases affect prescription access. Addressing the crisis requires a multi-faceted approach that considers not only prescribing practices but also underlying socioeconomic determinants and healthcare disparities. Acknowledging the complex interplay of demographics, economic hardship, and systemic inequities is crucial for developing effective, targeted interventions.
