Occupational health researchers at Colorado State University are drawing attention to worker safety and satisfaction in a young industry still finding its feet: legal cannabis.
CSU researchers in the Department of Psychology have completed a first-of-its-kind, peer-reviewed study that examines the demographics, physical environment and psychosocial aspects of working in the cannabis trade, which is now legal in some form in over half the United States, including Colorado. The study results were published in the American Journal of Industrial Medicine.
The study, led by psychology graduate student Kevin Walters, is a snapshot of who works in the cannabis industry in Colorado. It outlines potential improvements in worker health and safety, and it delineates specific hazards for workplaces to take note of, from ergonomic concerns due to trimming plants to slips, trips and falls.
"We don't want our work to be the end," Walters said. "We're just starting to build a conversation."
The study extends from a report co-authored by Walters, published last year, which was aimed at cannabis industry leaders. Both documents rely on results of a 214-person survey of cannabis industry workers across the Front Range of Colorado. The population sampled was "direct to plant," meaning employees who come in contact with cannabis plants or products at work every day.
The participants were asked about their occupation, job tasks, well-being, occupational health and safety, and cannabis and tobacco use.
The results found that workers were generally job-secure and valued safety. They also regularly consumed cannabis, expressed low concerns about workplace hazards, and reported occupational injuries and exposures.
Working in the industry, the authors found, is associated with positive outcomes for workers. But there is an imminent need to establish more formal health and safety training and guidelines in order to build up a culture of best practices. According to survey results, about 46 percent of respondents reported little to no worker safety training since beginning their employment.
The need to evaluate the cannabis workforce is gaining ground in the public health sphere. The state of Colorado recently published an industry-specific guide to worker health and safety. In June and November, the Center for Health, Work & Environment at the Colorado School of Public Health, and the Colorado Department of Public Health and Environment, jointly hosted safety trainings that highlighted many of the issues Walters' study outlined. To date, these organizations have trained more than 220 people. The course, the first of its kind, is now available online.
Work on the study was funded by the Mountain & Plains Education and Research Center (MAP ERC), which is supported by the Centers for Disease Control's National Institute for Occupational Safety and Health and housed within the Center for Health, Work & Environment. Walters is in the MAP ERC's occupational health psychology graduate training program.
Walters stressed that the study was a team effort by co-authors, mentors and industry partners. The study's co-authors are Gwenith Fisher, CSU associate professor in industrial-organizational psychology and previously Walters' adviser; and Liliana Tenney, deputy director of the Center for Health, Work & Environment. Walters' adviser at CSU is Kurt Kraiger, a professor in industrial-organizational psychology, who also provided guidance for the study.
