Parents' Perceptions of Adolescent Exposure to Marijuana Following Legalization in Washington State

OBJECTIVE

Parents in Washington State face new challenges related to the non-medical marijuana legislation that was passed in 2012. We asked parent focus group participants about changes they have observed in their environment, how their children are exposed to marijuana, and how this exposure might affect youth marijuana use.

METHOD

We conducted 6 focus groups with parents of youth ages 8 to 15 (N = 54). Parents were recruited from the Seattle Social Development Project, a multi-ethnic, longitudinal panel study that originated in Seattle in 1985. Thematic content analysis was used to analyze qualitative data.

RESULTS

Parents agreed that they did not want their children using marijuana, and were concerned that their children were exposed to marijuana more often and in many different contexts. Parents said they now need to monitor their children's environment more carefully, especially the other adults that spend time around their children. Edible marijuana products were particularly concerning for parents, as they offer a new set of challenges for parents in monitoring their children's exposure to and use of marijuana. Parents were concerned that marijuana exposure would increase risk of marijuana use in adolescents.

CONCLUSIONS

Parents' experiences in Washington State provide valuable lessons for social work practitioners, policymakers and those developing preventive interventions. Prevention efforts and public health messaging should begin before legalization takes effect to support parents in preparing for changes in their social and physical environments, and should seek to incorporate parenting strategies to monitor and intervene when children are exposed to marijuana.

The Impact of Marijuana Legalization on Adolescent Use, Consequences, and Perceived Risk

BACKGROUND

Currently, only four states have legalized recreational marijuana use for adults over 21 years of age. Therefore, little is known about the influence that legalization will have on adolescent marijuana use.

OBJECTIVES

This study examines how marijuana legalization has impacted the frequency and consequences of adolescent use in a sample of participants in a school-based, substance use intervention. We hypothesized that adolescents enrolled in the intervention in years after marijuana legalization would present with more problematic use compared to those enrolled prior, and that changes in the perceived risk of marijuana would be a mechanism of problematic use.

METHODS

Participants were 262 students enrolled in a school-based substance use intervention in 2010 to 2015. The Customary Drinking and Drug Use Record, Alcohol and Drug Use Consequences Questionnaire, and a decisional balance matrix were used to assess marijuana frequency, negative consequences, and perceived risk of use. A mediation model was used to test the degree to which marijuana legalization may lead to increased frequency and consequences of use through perceived risk.

RESULTS

Findings indicated a significantly positive correlation between marijuana-related consequences and perceived risk post legalization. Despite relatively equal use between both groups, adolescents in the legalization group experienced higher levels of perceived risk and increased negative consequences.

CONCLUSIONS/IMPORTANCE

Due to the rising legalization status of marijuana in the United States, it is imperative that psychoeducation is provided to adults and adolescents about the consequences of underage marijuana use.

Does heavy adolescent marijuana use lead to criminal involvement in adulthood? Evidence from a multiwave longitudinal study of urban African Americans

While marijuana use is common during adolescence, it can have adverse long-term consequences, with serious criminal involvement being one of them. In this study, we utilize longitudinal data from the Woodlawn Study of a community cohort of urban African Americans (N=702) to examine the effects of heavy adolescent marijuana use (20 or more times) on adult criminal involvement, including perpetration of drug, property and violent crime, as well as being arrested and incarcerated. Utilizing propensity score matching to take into account the shared risk factors between drug use and crime, regression analyses on the matched samples show that heavy adolescent marijuana use may lead to drug and property crime and criminal justice system interactions, but not violent crime. The significant associations of early heavy marijuana use with school dropout and the progression to cocaine and/or heroin use only partially account for these findings. Results suggest that the prevention of heavy marijuana use among adolescents could potentially reduce the perpetration of drug and property crime in adulthood, as well as the burden on the criminal justice system, but would have little effect on violent crime.
