Seeing is believing: How cannabis marketing exposure is associated with cannabis use attitudes and behavior in a permissive medical cannabis policy environment.

Background and Objectives: Oklahoma has a fast‐growing medical cannabis industry, showing a proliferation of industry marketing. While cannabis marketing exposure (CME) is a risk factor for cannabis use and positive attitudes about use, no studies have examined the impact of CME on attitudes and use behavior in a permissive cannabis policy environment, like Oklahoma. Methods: N = 5428 Oklahoma adults ages 18 and older completed assessments of demographics, past 30‐day cannabis use, and past 30‐day exposure to each of four types of cannabis marketing: outdoor (billboards, signs), social media, print (magazines), and Internet. Regression models examined associations of CME with positive attitudes towards cannabis use, cannabis harm perceptions, interest in obtaining a medical cannabis license (among nonlicensed participants), and past 30‐day cannabis use. Results: Three quarters (74.5%) reported any past 30‐day CME. Outdoor CME was most prevalent (61.1%), followed by social media (46.5%), Internet (46.1%), and print (35.2%). Correlates of CME included younger age, higher educational attainment and income, and medical cannabis license. In adjusted regression models, past 30‐day CME and number of sources of CME were associated with current cannabis use behavior, positive attitudes about cannabis, lower cannabis harm perceptions, and greater interest in obtaining a medical cannabis license. Similar associations between CME and positive attitudes about cannabis were shown among noncannabis users. Discussion and Conclusions: Public health messaging should be employed to minimize the potential adverse impacts of CME. Scientific Significance: No studies have examined correlates of CME in a rapidly growing and relatively unrestrained marketing environment. Answer questions and earn CME credit [ABSTRACT FROM AUTHOR]
