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.

OBJECTIVE: Substance use disorders (SUD) affect approximately 19.3 million adults in the United States. Of adults with SUDs, only 5% perceive the need for SUD treatment and 10% utilize specialty SUD treatment. The literature evidences racial disparities in utilization of SUD treatment yet presents mixed outcomes regarding race/ethnicity (i.e., White, Latinx, and Black/African-American) and gender (i.e., male, female) differences in perceived need for SUD treatment, specialty SUD treatment utilization, and barriers to SUD treatment. In addition, interaction with healthcare systems for chronic medical conditions like diabetes or hypertension may facilitate connection to SUD treatments for individuals with co-occurring SUD and chronic medical conditions, but little research exists that explores this potential facilitator. This dissertation addresses the following questions, with a focus on race/ethnicity and gender, and their interaction: 1.) What characteristics are associated with perceiving a need for SUD treatment among adults with SUD? 2.) What are the characteristics of adults who do not engage in specialty SUD treatment among those who perceived a need for SUD treatment? What were the most commonly reported barriers to specialty SUD treatment? and 3.) Is receipt of a chronic medical condition diagnosis among individuals with SUD associated with a greater likelihood of specialty SUD treatment utilization? METHODS: This study uses data from the National Survey on Drug Use and Health (NSDUH) from years 2005 through 2017. Simple and multivariate logistic regressions were conducted and interactions were tested using multiplicative terms with race/ethnicity and gender. Analyses adjusted for weights to account for the survey’s complex sampling design. RESULTS: No significant racial/ethnic or gender differences were found in association with perceived need for SUD treatment. Among adults who perceived the need for SUD treatment, less than 20% in any racial/ethnic category utilized specialty SUD treatment services. Black/African-American adults, compared to White, were more likely to utilize specialty SUD treatment and less likely to name stigma as a barrier to treatment. Black/African-American adults with co-occurring chronic medical conditions and SUD were more likely to perceive a need for SUD treatment, but similarly likely to utilize specialty SUD treatment in comparison to White adults. Women and men did not significantly differ on perceived need for SUD treatment, utilization, or barriers. CONCLUSIONS: Differences in SUD treatment utilization patterns exist in association with race/ethnicity, though not with gender. Study findings suggest the presence of specialty SUD treatment utilization disparities, with stigma contributing to lower utilization for Whites compared to Blacks/African-Americans. Higher rates of treatment utilization among Blacks/African-Americans may reflect the presence of strengths uniquely attributed to this group.

Marijuana is the most common illicit drug that is abused by pregnant women, and recently many states have adopted various levels of relaxed marijuana policies. The purpose of this study was to evaluate a potential association between residing in a state that allows medical marijuana use and maternal marijuana usage. Grounded in the theory of planned behavior, this study evaluated the prevalence and extent of maternal marijuana use in states that allow and states that do not allow medical marijuana use using the National Survey of Drug Use and Health (NSDUH). It was anticipated that more lenient subjective norms toward marijuana use and increased availability would support an increase of maternal marijuana use. The 2014 NSDUH was queried and analyzed using chi-square and logistic regression. The study revealed an increase of maternal marijuana use in states where medical marijuana was allowed, but the increase was not statistically significant. An increase of heavy users was observed in states where medical marijuana was allowed (54% versus 37%). Consistent with other research findings, this study revealed that young (OR = 3.56; 95% CI: 1.379, 9.213; p = 0.009) and unmarried (OR = 6.81; 95% CI: 2.485, 18.661; p < 0.001) pregnant woman were at higher risk for past month maternal marijuana use and had similar results for past year use. The unintended consequences of increased in utero marijuana exposure and its subsequent negative public health effects have been missing from the discussion of the relaxation of statewide marijuana policies. This study will provide policy makers responsible for changing marijuana policy with useful evidence on the unintended consequences of increased maternal marijuana use in areas where medical marijuana is allowed.
