Accidental cannabis poisoning in the elderly

Area of Science:

• Pharmacology
• Toxicology
• Cannabis Science

Background:

• Cannabis sativa exists in two main varieties: hemp (low psychoactive cannabinoids, used for fiber/seeds) and drug cannabis/marijuana.
• The growing popularity of hemp products and perceived benefits of cannabinoids may cause public confusion.
• This confusion can lead to unintentional consumption of marijuana.

Observation:

• During a hemp workshop, attendees consumed various hemp food products, including cookies.
• Within an hour, participants reported symptoms such as nausea, vomiting, dizziness, sleepiness, and difficulty walking.
• Twelve individuals sought emergency care, with two admitted to intensive care due to central nervous system depression.

Findings:

• Ingestion of hemp-based food products led to acute psychoactive cannabinoid intoxication.
• Symptoms were consistent with significant marijuana exposure, despite the presumed hemp origin of the food.
• All affected individuals recovered with supportive care, indicating the transient nature of the effects.

Implications:

• Highlights the critical need for accurate product identification and clear labeling of cannabis-derived foods.
• Underscores the potential risks of accidental marijuana consumption due to product misidentification.
• Emphasizes the importance of consumer education regarding the differences between hemp and marijuana products.
