abstract: Maternal cigarette smoking and marijuana use during pregnancy are risk factors that can adversely affect offspring. Although a large body of empirical literature has examined the adverse health effects of maternal cigarette smoking and marijuana use during pregnancy, few studies have looked at criminological factors associated with prenatal cigarette smoking and marijuana use. This thesis uses strain theory and social learning theory to explain a number of underlying mechanisms behind why some pregnant women decide to smoke tobacco and marijuana cigarettes during pregnancy. Previous drug involvement before pregnancy is also used to determine if it is a predictor of maternal cigarette smoking during pregnancy. Logistic regression was used to analyze data collected from the 1988 National Pregnancy and Infant Health Survey. This data set consists of information gathered from three different national samples of maternal and infant data occurring in 1988, which included 13,417 live births, 4,772 fetal deaths, and 8,166 infant deaths. The mothers in the sample were mailed questionnaires. Results showed that pregnant women who have unexpected pregnancies and experience financial hardship during pregnancy are more likely to smoke cigarettes and use marijuana during pregnancy, which is consistent with the general strain theory. Results also indicate that pregnant women who live in households with other people who smoke are more likely to smoke cigarettes during pregnancy, which may be explained by social learning, and that women who use illegal drugs are less likely to smoke cigarettes during pregnancy, even after controlling for strain and social learning. The practical and theoretical implications for this research are discussed. / Dissertation/Thesis / M.S. Criminology and Criminal Justice 2014

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.
