Downstream costs can be difficult to estimate. The $1.77 trillion total for addiction's economic burden is fairly conservative. In March 2025 the White House Council of Economic Advisers put the cost of illicit opioids alone at $2.7 trillion a year. A review of the published cost studies supports a range of roughly $1.4 to $2.5 trillion per year, and the $1.77 trillion figure sits at the low end of that range.

Direct medical care

Polysubstance overlap discounted ~15–25%.

• CDC Smoking-Attributable Mortality, Morbidity, and Economic Costs (SAMMEC). (>$240B/yr smoking-attributable medical care, 2018)
• Shrestha SS et al. Smoking-attributable medical expenditures. American Journal of Preventive Medicine, 2022. (part of the >$600B/yr total cost of smoking)
• Sacks JJ et al. 2010 national and state costs of excessive alcohol consumption. American Journal of Preventive Medicine, 2015. ($28B/yr alcohol healthcare, 2010)
• Florence CS et al. Healthcare costs of opioid use disorder. Drug and Alcohol Dependence, 2021. ($31B/yr opioid healthcare, 2017)

Lost productivity

• Shrestha SS et al. (above). (~$185B/yr smoking productivity losses, 2018)
• Sacks JJ et al. (above). ($179B/yr alcohol productivity, 2010)
• Florence CS et al. (above). (~$31B/yr opioid productivity, 2017)

Premature mortality

COI uses lifetime lost earnings. Hybrid frameworks that monetize premature deaths via the Value of Statistical Life (CEA 2017, CEA 2025, JEC 2022) would increase the US total to around $2.0–2.7 T/yr.

• CDC SAMMEC. (~480,000 smoking deaths/yr; ~$180B lost productivity)
• Esser MB et al. Deaths from excessive alcohol use, United States, 2016–2021. MMWR, 2024. (≈178,000 alcohol-attributable deaths/yr)
• CDC NCHS overdose mortality data. (~107,000 overdose deaths in 2023; nearly 27% lower in 2024)

Criminal justice

• National Drug Intelligence Center. The economic impact of illicit drug use on American society, 2011 (inflated to 2024 USD). ($113B/yr criminal-justice and victim costs, 2007; about $170B in 2024 USD)
• Florence CS et al. (above). (~$15B/yr opioid criminal justice, 2017)

Family & child welfare

• ACF / AFCARS Report #30 (foster-care population baseline). (343,000 children in foster care, 2023)

Intergenerational harm

• Peterson C et al. Annual estimates of US adverse childhood experiences (ACE)–attributable health-condition costs. JAMA Network Open, 2023. ($14.1T/yr ACE-attributable; an estimated 15–20% tied to SUD-driven ACEs, so roughly $2–2.8T)
• Bellis MA et al. Life-course health consequences and public-health cost of ACEs. Lancet Public Health, 2019. (~$748B/yr across North America)

Cancer comparison

• National Cancer Institute, Cancer Trends Progress Report: national cancer-care expenditures (about $209B in 2020, projected to $246B by 2030; Mariotto AB et al., JNCI). Basis for the $240B medical (above-water) figure.
• Islami F et al. National and State Estimates of Lost Earnings From Cancer Deaths in the United States. JAMA Oncology, 2019 ($94.4B in lost earnings from 2015 cancer deaths, ages 16–84). Basis for the $94B premature-death line.
