The 287-page report, Shoveling Up II: The Impact of Substance Abuse on Federal, State and Local Budgets, is based on data collected and analyzed over three years. CASA researchers' intent was to undertake the most comprehensive measurement to date of the costs of substance abuse and addiction to all levels of government. They looked beyond the usual categories in which such spending is estimated—prevention, treatment, research, taxation and regulation, and interdiction—to the much larger costs buried in government budgets, such as spending on health care; the criminal, juvenile, and family court systems; incarceration; child welfare; domestic violence and child abuse; homelessness; and mental illness and developmental disabilities.
