NIH Funded Research on Cannabis Facility Air Hazards
The University of Colorado Boulder will study airborne mold and allergens to improve safety for cannabis workers.
Updated on Oct. 1, 2026 in Asthma

The National Institutes of Health awarded a research grant to the University of Colorado Boulder to examine airborne hazards in cannabis facilities. Researchers will analyze air samples for mold and allergens to determine safe working conditions.
Why it matters
The study aims to address workplace safety concerns following reports of severe respiratory issues among cannabis employees. Determining appropriate thresholds for airborne bioaerosols is a critical step in preventing future work-related health complications.
The study follows a 2024 fine of $350,000 issued to Trulieve Cannabis by Massachusetts regulators for safety violations. Researchers are currently collecting air samples to identify the presence of specific mold and allergen bioaerosols.
The players
National Institutes of Health
This federal agency is the primary medical research branch of the United States government.
University of Colorado Boulder
This public research university in Boulder is the institution leading the new study on cannabis worker safety.
Trulieve Cannabis
This company is a prominent cannabis producer that faced a significant regulatory fine in 2024.
Joel Michaely Farms
This agricultural entity is located in Lake County, California, and was subject to a license suspension.
The details
The project focuses on the risks posed by airborne materials during cannabis cultivation and manufacturing. The initiative was launched in response to documented health incidents, including the 2022 death of Lorna McMurrey and the August 2026 death of Yufang Lan.
Timeline
2020: A California cannabis worker died from work-related asthma.
2022: Lorna McMurrey died at a Massachusetts cannabis facility.
2024: Massachusetts regulators fined Trulieve Cannabis $350,000.
August 27, 2026: Yufang Lan died at Joel Michaely Farms.
The Big Picture
The research project directly follows the pattern of increased federal and regulatory scrutiny established by the 2022 death of Lorna McMurrey in Massachusetts. This effort marks a shift toward scientific standardization in a rapidly growing, but previously under-regulated, industry.
The findings from this study could lead to new workplace safety standards that directly protect the health of individuals employed in cannabis facilities. These guidelines may eventually influence broader occupational health protocols for workers exposed to organic dusts and allergens.
The takeaway
This research highlights the growing importance of occupational health oversight as the cannabis industry matures. Workers and facility managers should monitor emerging safety guidelines to ensure indoor air quality meets necessary health standards.
