"Despite the many factors that contribute to the gap, the Panel agrees with many in the field that inadequate funding for substance abuse treatment is a major part of the problem. Over the last decade, spending on substance abuse prevention and treatment has increased, albeit more slowly than overall health spending, to an estimated annual total of $12.6 billion in 1996 (McKusick, Mark, King, Harwood, Buck, Dilonardo, and Genuardi, 1998). Of this amount, public spending is estimated at $7.6 billion (McKusick, et al., 1998). The public spending includes dollars from Medicaid and Medicare, as well as other Federal funds from the Department of Defense, the Department of Veterans Administration, the Department of Justice, and the Substance Abuse Prevention and Treatment (SAPT) Block Grant. The SAPT Block Grant provides Federal support to addiction prevention and treatment services nationally through State and local governments. Private spending includes individual out-of-pocket payment, insurance, and other nonpublic sources, and is estimated at $4.7 billion (McKusick, et al., 1998)."
