Cannabis Use and Workers

What to know

In light of rapidly changing laws and public attitudes, NIOSH has developed a framework for addressing workers' safety, health, and well-being related to cannabis. The framework focuses on guiding questions for future research.

Overview

Cannabis is a genus of flowering plants. It contains compounds called cannabinoids that can have a wide range of effects on the body and brain. Cannabinoids are products found in a cannabis plant (e.g., tetrahydrocannabinol [THC] and cannabidiol [CBD]).

Employers in all industries face challenges addressing issues of impairment among workers who consume cannabis. This is especially true for workers in safety-sensitive positions. As laws, regulations, and attitudes change related to consuming cannabis, workers' health, safety, and well-being must also be addressed. Recognizing these rapidly occurring changes, NIOSH seeks to:

  • Better understand cannabis and work-related issues
  • Provide advice on workplace policies, programs, and practices

At a glance: Framework

NIOSH has developed a framework for addressing workers' safety, health, and well-being related to cannabis, in light of rapidly changing laws and public attitudes, and includes guiding questions for future research. Learn more about these needs in Cannabis and work: need for more research.

NIOSH Framework for Cannabis and Work

Societal issues that impact cannabis production, distribution, and consumption:

  • Conflicting state and federal regulations
  • Cultural and social views
  • Economics
  • Hazards
  • Policies
  • Politics

Occupational safety and health priorities:

  • Cannabis consumption by workers
  • Cannabis industry workplace safety and health hazards
  • Illegal cannabis production, synthetically-produced hemp-derived cannabinoids, and synthetic cannabinoid use

Guiding questions

  • What trends and patterns exist for cannabis use by workers?
  • What are adverse health consequences of cannabis consumption among workers?
  • What is the role of cannabis in:
    • medical treatment for workers?
    • treating work-related health conditions?
    • managing chronic pain from an occupational injury?
  • Does cannabis consumption impact occupational safety and performance?
  • What evidence-based cannabis-related workplace policies exist, including for:
    • drug-testing
    • impairment detection
    • reasonable accommodation of medical cannabis use
  • What is the impact of workers' unintentional cannabis exposure, such as those exposed to second-hand cannabis smoke?
  • What are the impacts of cannabis consumption or exposure on occupational driving?
  • What is the extent and impact of use or exposures of workers to synthetically-produced hemp-derived cannabinoids or synthetic cannabinoids?
    • Examples of synthetically-produced hemp-derived cannabinoids include Delta-8 THC or Delta-10.
    • Synthetic cannabinoids are a class of laboratory made substances similar to chemicals found in the cannabis plant. Examples include 'Spice' or 'K2'.
