This is an intermediate case study based on an outbreak caused by the unintentional ingestion of cannabis-infused foods (edibles) at a county fair in Colorado.
Learning Objectives
- Give an example of an unintentional marijuana exposure.
- Name agencies that may be involved in an unintentional marijuana exposure
investigation. - List available resources that address marijuana exposure.
- Formulate interview questions for an unintentional marijuana exposure investigation.
- Establish a case definition for marijuana exposure.
- List special considerations that should be made during an environmental assessment of
a marijuana facility. - Recommend control measures to prevent unintentional marijuana exposure in the future.
Format & Time Commitment
This case study is designed to be discussed in-person or via bi-directional video with a small
group (up to 15 participants) led by an instructor or facilitator with experience investigating
foodborne outbreaks. We recommend allowing 2 hours to complete the case study.
Required materials may include pens, paper, a whiteboard, and calculators. Some activities
would benefit from having internet access.
Prerequisites & Audience
Participants should have a basic knowledge of epidemiologic concepts and methods. This activity is designed to facilitate a discussion among epidemiologists and other public health professionals about how to respond to an outbreak involving a marijuana-infused food.
