The study was first slated to take place at Trulieve in Holyoke, where an employee died in January 2022. The 27-year-old production technician suffered a fatal asthma attack while working at the indoor cannabis cultivation and processing facility. According to the Massachusetts Department of Public Health (DPH), the death occurred seven months after she started employment at the facility and three months after she began working as a flower technician, which involved processing and handling whole and ground cannabis flower buds.
One of his employees with specific sensitivity concerns actually wears not only a Tyvek suit with a particulate mask, but also gloves duct-taped to the sleeves so the dust doesn't get up the sleeves.
During the on-site visit, NIOSH will set up airborne particulate monitoring during the grinding process to see what the exposure is and how many airborne particulates employees are subject to.
"We use dust masks, basically particulate masks, and that should be enough in most cases. We're not talking chemical fumes; it's simply airborne particulates," Dailey said. "But we need to know whether we need to go to N95 or a higher level to make sure enough particulates are captured."
Also in the wake of the death at Trulieve, the Massachusetts Department of Public Health (DPH) recently released an investigative report outlining additional steps the cannabis industry should take to prevent work-related asthma and sent a bulletin to healthcare providers in the Commonwealth urging vigilance in identifying work-related asthma among workers in that industry. The bulletin reminds providers that they are mandated to report cases of work-related asthma and other respiratory diseases to DPH.
While the Holyoke death is the only known asthma death in the U.S. cannabis industry, other cases of non-fatal respiratory disease among Massachusetts cannabis workers have been reported. According to DPH, cannabis-industry workers can be routinely exposed to numerous occupational respiratory hazards, including cannabis dust, mold, volatile organic compounds, pollen, bacterial endotoxins, pesticides, soil components, and cleaning disinfectants, which can cause and/or exacerbate chronic diseases, like asthma, if not addressed.
Massachusetts has more than 500 licensed cannabis industry employers providing jobs to more than 22,000 workers.
"The legalized cannabis industry in Massachusetts is relatively new, and the impact on the health and safety of workers demands our careful attention," Public Health Commissioner Dr. Robert Goldstein noted in a statement. "As this workforce continues to expand, it will require all of us working together - state and federal agencies, regulators, healthcare providers, and the cannabis industry - to improve working conditions for these employees. At DPH, we will continue to identify and follow up on these cases using our long-standing public-health surveillance system for work-related respiratory disease and continue to work with our partners on documenting cases, building evidence around workplace hazards, and on intervention and policy."
According to DPH, work-related asthma is underrecognized in part because symptoms and industry and occupation data are not routinely collected. Yet, about 17% of new-onset adult asthma cases are related to workplace exposures. In Massachusetts, an estimated 200,000 adults have work-related asthma, according to data from DPH's Occupational Health Surveillance Program.
• Report cases of work-related asthma and other work-related respiratory diseases to DPH, as required by law.
The report also noted that equipment manufacturers should adopt and implement the concept of 'prevention through design' to identify potential hazards associated with equipment and then eliminate these hazards through design changes; and that industry licensing agencies in Massachusetts should consider how they can further support the health and safety of cannabis-industry workers.
"Levels of exposure to cannabis dust at work are much higher than what is present during recreational use," said Emily Sparer-Fine, director of DPH's Occupational Health Surveillance Program. "Work processes that include grinding and concentrating an allergen need to be better controlled. It is critical for employers to assess and control exposure to hazardous materials, including the respiratory hazards found in the cannabis-processing facilities, such as cannabis dust."
All this is gratifying to Dailey, who thanked Stair for ensuring that the NIOSH Study was completed, advocating for the safety cannabis-industry employees, and helping prevent future injuries or deaths. Dailey claimed that larger cannabis companies are prioritizing profits and growth over workplace safety, so it is important that advocates and smaller companies step up to take the lead in setting industry standards to ensure workplace safety.
