Marijuana Use and Its Association with Participation, Navigation, and Enrollment in Health Research among African Americans.

ABSTRACT: This analysis examined the association between marijuana (Mj) use, willingness to participate, navigation and enrollment in health research among African Americans. Data from HealthStreet, a community-engagement model implemented in North Central Florida that reduces health disparities by engaging and linking community members to medical and social services and health research opportunities, were analyzed to determine willingness of African American Mj users to participate, be navigated to and enroll in health research studies. Among 1,496 African American community members, 8.0% were current Mj users, 30.3% were past Mj users and 61.7% reported never using Mj. Current and past Mj users were more willing to volunteer for a research study that only involved the use of medical records, required an overnight stay in a hospital or clinic, or might require use of medical equipment compared to those who never used Mj. Current Mj users were significantly less likely to be navigated (95% CI: 0.21-0.58) to health research studies while past Mj users (95% CI: 1.05-2.64) were significantly more likely to be enrolled in health research studies. Navigating and enrolling Mj users into health research studies could help decrease health disparities and increase health equity for the entire community since study findings would undoubtedly be more representative of the entire community rather than a select few.

Project description:ObjectiveTo elucidate factors that influence African American willingness to participate in health-related research studies.MethodsThe African American Alzheimer disease research study group at North Carolina A&T State University designed an in-person questionnaire and surveyed more than 700 African American adults on their willingness to participate in health-related research studies. The questionnaire was distributed and collected in a nonclinical setting during the years 2008 and 2009. This study was approved by the North Carolina A&T State University Institutional Review Board.ResultsOf the 733 valid respondents, 16% had previously participated in a health-related research study. Of these, more than 90% were willing to participate again in future research studies. Of the 614 who had never participated in a research study, more than 70% expressed willingness to participate. The majority (75%) of experienced research study participants (RSP) were older than 40 years compared with 45% of non-research study participants. Experienced research participants were also twice as likely to have a college degree compared with non-research study participants. Seventy-three percent of non-research study participants were willing to participate in research studies in the future. The factors that were probable impediments to participation included lack of time and trust. Men with knowledge of the Tuskegee Syphilis Study were 50% less likely to be willing to participate compared with those who had not heard of Tuskegee Syphilis Study.ConclusionsAfrican Americans are willing to participate in health-related research studies. Several factors such as the appropriate incentives, community trust building, outreach, and community partnership creation are necessary for engaging minority participants. Incorporating factors that target African American enrollment in research design and implementation, such as increased training of minority health ambassadors and African American researchers and public health specialists, are needed to better engage minorities across generations, in research.

Project description:ImportanceHistorical shifts are occurring in marijuana policy. The effect of legalizing marijuana for recreational use on rates of adolescent marijuana use is a topic of considerable debate.ObjectiveTo examine the association between the legalization of recreational marijuana use in Washington and Colorado in 2012 and the subsequent perceived harmfulness and use of marijuana by adolescents.Design, setting, and participantsWe used data of 253 902 students in eighth, 10th, and 12th grades from 2010 to 2015 from Monitoring the Future, a national, annual, cross-sectional survey of students in secondary schools in the contiguous United States. Difference-in-difference estimates compared changes in perceived harmfulness of marijuana use and in past-month marijuana use in Washington and Colorado prior to recreational marijuana legalization (2010-2012) with postlegalization (2013-2015) vs the contemporaneous trends in other states that did not legalize recreational marijuana use in this period.Main outcomes and measuresPerceived harmfulness of marijuana use (great or moderate risk to health from smoking marijuana occasionally) and marijuana use (past 30 days).ResultsOf the 253 902 participants, 120 590 of 245 065(49.2%) were male, and the mean (SD) age was 15.6 (1.7) years. In Washington, perceived harmfulness declined 14.2% and 16.1% among eighth and 10th graders, respectively, while marijuana use increased 2.0% and 4.1% from 2010-2012 to 2013-2015. In contrast, among states that did not legalize recreational marijuana use, perceived harmfulness decreased by 4.9% and 7.2% among eighth and 10th graders, respectively, and marijuana use decreased by 1.3% and 0.9% over the same period. Difference-in-difference estimates comparing Washington vs states that did not legalize recreational drug use indicated that these differences were significant for perceived harmfulness (eighth graders: % [SD], -9.3 [3.5]; P = .01; 10th graders: % [SD], -9.0 [3.8]; P = .02) and marijuana use (eighth graders: % [SD], 5.0 [1.9]; P = .03; 10th graders: % [SD], 3.2 [1.5]; P = .007). No significant differences were found in perceived harmfulness or marijuana use among 12th graders in Washington or for any of the 3 grades in Colorado.Conclusions and relevanceAmong eighth and 10th graders in Washington, perceived harmfulness of marijuana use decreased and marijuana use increased following legalization of recreational marijuana use. In contrast, Colorado did not exhibit any differential change in perceived harmfulness or past-month adolescent marijuana use following legalization. A cautious interpretation of the findings suggests investment in evidence-based adolescent substance use prevention programs in any additional states that may legalize recreational marijuana use.
