Characteristics and Trends in Child Cannabis Exposures During Legalization in California.
Introduction: In 2016, California legalized cannabis for adult recreational use; after recreational sales began in 2018, it became the largest retail market worldwide. This study profiled specific risks and prevention opportunities across age groups and examined changes in medically significant child cannabis exposures before and after legalization.
Methods: Researchers conducted analyses, including interrupted time-series, to examine 1695 California Poison Control System (CPCS) reports of cannabis exposure in children 0-17 years of age, from 2010-2020. Analyses were confined to moderate and severe exposures, identified by CPCS toxicologists as requiring medical attention.
Results: Monthly rates of moderate/severe cannabis exposure per million children increased following legalization (β=0.06, CI [0.05, 0.08]), especially in children under 5. Fourteen percent required critical care admission. Exposures were primarily unintentional in younger children (87.7-99.2%) and intentional in adolescents (85.5%). Across all ages, most exposures occurred in the home (94.0%) and involved edible products (83.5%). An analysis of packaging on edible brands frequently cited in health records found that most could be easily mistaken for popular candies and snack foods.
Conclusions: Following cannabis legalization in California, reports of child cannabis exposures requiring medical attention increased significantly. Most reported cannabis exposures occurred in the home through the ingestion of edible products, often packaged to look like popular candy and snack food brands. To prevent these harms, cannabis legalization should be accompanied by robust marketing and packaging regulations (e.g., plain labels, larger warning labels). Secondary prevention should focus on educating parents and caregivers on safe cannabis storage in the home.
期刊介绍:
The American Journal of Preventive Medicine is the official journal of the American College of Preventive Medicine and the Association for Prevention Teaching and Research. It publishes articles in the areas of prevention research, teaching, practice and policy. Original research is published on interventions aimed at the prevention of chronic and acute disease and the promotion of individual and community health.
Of particular emphasis are papers that address the primary and secondary prevention of important clinical, behavioral and public health issues such as injury and violence, infectious disease, women''s health, smoking, sedentary behaviors and physical activity, nutrition, diabetes, obesity, and substance use disorders. Papers also address educational initiatives aimed at improving the ability of health professionals to provide effective clinical prevention and public health services. Papers on health services research pertinent to prevention and public health are also published. The journal also publishes official policy statements from the two co-sponsoring organizations, review articles, media reviews, and editorials. Finally, the journal periodically publishes supplements and special theme issues devoted to areas of current interest to the prevention community.
