High rates of nonmedical use of pain relievers and stimulants have been documented in the United States, putting substance abusers at risk of addiction and possible arrest for illegal possession and use. Treatment programs can help stop patterns of abuse. This thesis explores the factors impinging on substance abuse treatment seeking for nonmedical pain reliever and stimulant users. Data from the National Survey of Drug Use and Health 2014 were analyzed in order to find the most recent patterns of pain reliever and stimulant abuse and potential determinants of receiving treatment. Descriptive statistics about the population reporting nonmedical use of pain relievers and/or stimulant use are first presented. Logistic regression analyses are then conducted on one dependent variable: respondents stating if they ever received treatment. Possible determinants that may influence one’s potential to receive treatment included income, insurance coverage, race/ethnicity, age, sex, psychological state, and metro/nonmetro residency status.
