^aSource: National Survey on Drug Use and Health, 2008–2009. Ns are unweighted and percentages are weighted to make estimates representative of the noninstitutionalized population. The income eligibility threshold reflects 133% of the federal poverty level provided in the Affordable Care Act plus a 5% income “disregard” allowed by the law.

^bInsurance categories are defined to be mutually exclusive and exhaustive. Therefore, columns sum to 100%.

^cIndividuals with symptoms of both dependence and abuse were coded as dependent.

^dIncludes individuals currently reporting coverage by TRICARE, CHAMPUS, CHAMPVA, the Department of Veterans Affairs, or military health care

^ep<.01 for the difference in insurance distribution between individuals with and without a substance use disorder; p=.08 for the difference in insurance distribution between individuals with alcohol or illicit drug dependence and individuals with alcohol or illicit drug abuse
