Cannabis poisonings among older adults have tripled, study finds
Triple Spike in Elderly Cannabis Poisonings: Why?
In Canada, cannabis poisonings among older adults have tripled since the legalization of cannabis edibles in January 2020, according to a study published in JAMA Internal Medicine. The study found a significant increase in emergency department visits for cannabis poisoning in this age group, who may not be aware of the potency of today’s cannabis products. The research highlights the need for better education and guidelines to prevent cannabis-related harm in older adults.
How has the potency of cannabis changed over the years, according to Dr. Nathan Stall, and what impact might this have on older adults using cannabis today?
Dr. Nathan Stall, a geriatrician and clinician scientist at Sinai Health in Ontario, highlights that the potency of cannabis has significantly increased over the years. Today's cannabis extracts contain as much as 30 times more THC (delta-9-tetrahydrocannabinol), the major active ingredient in both medical and recreational cannabis, compared to cannabis from the early 1990s and mid-1980s. This increase in potency can have a greater impact on older adults using cannabis, as they may not be aware of the changed potency since their past experiences with the substance.
Higher potency cannabis can lead to cannabis poisoning, especially when consumed in the form of edibles. Edible cannabis products may contain high amounts of THC and are often indistinguishable from non-cannabis containing foods, making it easier for older adults to unintentionally consume a higher dose than intended. Additionally, age-related changes in organ function, how the drug is distributed throughout the body, having certain health conditions, or being on prescription drugs can make older adults more susceptible to cannabis poisoning.
It is essential for health care providers to have open and judgment-free conversations with older adults about cannabis use, its benefits, and risks. Preventing cannabis-related harms in older adults requires a multipronged approach, including storing cannabis edibles in locked locations and clearly identified packaging, providing specific dosing information and guidance for older adults, and encouraging a "start low and go slow" approach to consumption.
What was the average age of older adults who visited emergency departments for cannabis poisoning during the study period in Canada?
The average age of older adults who visited emergency departments for cannabis poisoning during the study period in Canada was 69 years old.
