In case-based learning, students develop and apply course knowledge to solve tangible and "real life" problems. This practice can enhance student motivation and engagement in the analytical laboratory. In this application of case-based learning students analyze commercially available oils for CBD content. In the state of Texas anyone can…

Background: Given its ability to exacerbate health inequities through its disproportionate impact on low-income communities, the need exists to better understand factors that influence substance use among adolescents. Moreover, given its multi-etiological nature, preventing adolescent substance use requires addressing intrapersonal, interpersonal,…

In recent years the pace has been accelerating by which changes in the Diagnostic and Statistical Manual of Mental Disorders (DSM) systems are made. Revisions occur before extensive empirical knowledge can be drawn upon to guide these changes. For substance use disorders, the criteria have undergone changes from DSM-III to DSM-III-R, and from…

The Cannabis Youth Treatment (CYT) study is a multi-site randomized field experiment examining five outpatient treatment protocols for adolescents who abuse or are dependent on marijuana. The purpose of the CYT project is twofold: (a) to test the relative clinical effectiveness and cost-effectiveness of five promising interventions targeted at…

This study examines the influence of perceived risks as well as the understudied role of benefits on alcohol and marijuana use among adolescents and adults. Ninth grade students and young adults were asked about the perceived risks and benefits of alcohol and marijuana use. Analyses showed a consistent pattern: perceived benefits were more…

Previous research has found a relation between substance use and academic achievement and motivation, although the direction of the causal relation is unclear. Whereas numerous researchers have found that substance use is predictive of graduation from high school, others have found that poor academic achievement and low academic aspirations have a…

Many researchers have studied predictors of adolescent substance use. One important predictor of substance use is the quality of the parent-child relationship. Most studies address the parent-child relationship unidimensionally. This study hypothesized that it is not use of a particular substance that can be predicted from a poor parent-child…

As levels of maternal employment increase (71% for mothers with school-age children), there is concern for both the short- and long-term consequences of maternal employment on children and families. This study examined the influence of maternal employment in two-parent families on the substance use of adolescents. Subjects were male and female…

Middle Tennessee State University (MTSU) conducted campus-wide surveys on drug and alcohol use in 1977, 1983, 1987, and 1992. This survey was generated during the 1992 Fall semester. Results show that alcohol and drug use at MTSU has changed little in 15 years. The most noticeable change was the reduced use of marijuana by males. Cigarette smoking…

Many questions about the associations between risk factors and drug use remain unanswered. Data originally obtained from seventh graders participating in a school-based prevention program were examined in terms of a theoretical model. A series of multiple regression analyses were then conducted to select those risk factors which contributed unique…

Past research based primarily on cross-sectional data, has suggested a Guttman scale of substance use onset where marijuana use is preceded by alcohol use, and where sometimes tobacco is placed between alcohol and marijuana. Prospective longitudinal data is needed to determine whether the stages form a temporal sequence. A new statistical…

Adolescent substance abuse is determined by a complex of factors, and influences on it may vary as a function of developmental level. According to the social development model (Hawkins et al., 1986), family influences on substance abuse may be strongest in preschool and early school-age children; family and school influences may be equal during…

This study examined psychosocial correlates of substance abuse during late adolescence. Older adolescents' (N=276) aged 17-22, self-reported use of marijuana, cocaine, and other illicit drugs was examined in relation to several psychosocial variables, including sensation seeking, aggression, self-esteem, depression, and perceived peer prevalence…

Changing alcohol and drug use patterns among women and ethnic minorities, such as the over-representation of Hispanics in alcohol-related deaths, drunk driving arrests, and treatment facilities, emphasize the importance of understanding substance use patterns in these populations. This study attempted to identify a single cause of substance abuse…

Substance abuse among adolescents is modeled and reinforced by the peer culture. Experimentation with drugs seems to have become a typical part of normal adolescent development. The solution to adolescent substance abuse will only be arrived at through gathering facts and designing intervention programs based on those facts. Since the two most…
