This is the first paper to measure the association between type of legal cannabis supply mechanism and traffic crashes involving injuries.<\/p>\n<p><strong>Design:&nbsp;<\/strong>Ecological study using ordinary least squares regression to examine how department-level variation in registrations (overall and by type) is associated with traffic crashes involving injuries.<\/p>\n<p><strong>Setting:&nbsp;<\/strong>Uruguay.<\/p>\n<p><strong>Cases:&nbsp;<\/strong>532 department-quarters.<\/p>\n<p><strong>Measurements:&nbsp;<\/strong>Quarterly cannabis registration counts at the department level and incident-level traffic crash data were obtained from government agencies. The analyses controlled for department-level economic and demographic characteristics and, as a robustness check, we included traffic violations involving alcohol for departments reporting this information. Department-level data on crashes, registrations, and alcohol violations were denominated by the number of residents aged 18 and older.<\/p>\n<p><strong>Findings:&nbsp;<\/strong>From 2013-2019, the average number of registrations at the department-quarter level per 10,000 residents aged 18 and older for self-cultivation, club membership, and pharmacy purchasing were 17.7 (standard deviaiton [sd]=16.8), 3.6 (sd=8.6), and 25.1 (sd=50.4), respectively. In our multivariate regression analyses, we did not find a statistically significant association between the total number of registrations and traffic crashes with injuries (\u03b2=-0.007; p=0.398; 95% confidence interval [CI]=-.023, .01). Analyses focused on the specific supply mechanisms found a consistent, positive, and statistically significant association between the number of individuals registered as self-cultivators and the number of traffic crashes with injuries (\u03b2=0.194; p=0.008; 95% CI=.058, .329). Associations for other supply mechanisms were inconsistent across the various model specifications.<\/p>\n<p><strong>Conclusions:&nbsp;<\/strong>In Uruguay, the number of people allowed to self-cultivate cannabis is positively associated with traffic crashes involving injuries. Individual-level analyses are needed to assess better the factors underlying this association.<\/p>\n<p><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/35129240\/\" target=\"_blank\" rel=\"noopener\" class=\"button\">For complete research <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(First nation (not jurisdiction) to legalize cannabis use for citizens was Uruguay.
