A growing body of research warns that cannabis use among older adults carries increasing health risks, a concern that grows as legalization expands and social attitudes shift. A recent analysis highlights a sharp rise in cannabis consumption among people aged 65 and older, sparking urgent discussions among health professionals about safety, regulation, and how Thailand should respond in its rapidly aging society.

A cautionary incident underscores the issue: a 76-year-old woman seeking insomnia relief consumed several THC-laced edibles in one night, experiencing anxiety and heart palpitations that led to an emergency visit. She recovered and was discharged, but the episode illustrates vulnerabilities many seniors face. As a geriatrician notes, aging brains are more sensitive to psychoactive substances, a reality for Thai seniors with hypertension or arrhythmias, where drug interactions and falls could amplify risks.

A growing wave of scientific research is sounding the alarm on the increasing health risks linked to cannabis use among older adults, as usage climbs to record levels amidst expanded legalization and shifting social attitudes. The latest analysis, published in the Journal of the American Medical Association (JAMA), reveals a sharp uptick in cannabis consumption by individuals aged 65 and older, igniting urgent debate among health experts about the safety, efficacy, and regulation of cannabis use in Thailand’s rapidly aging society.

A recent headline in international media warns that a common over-the-counter (OTC) medication, widely used for allergies, may increase the risk of dementia, prompting concern among health professionals and the public in Thailand and globally. Leading doctors cited in a recent report from Women’s Health Magazine are drawing attention to mounting research that connects the use of certain antihistamines—medicines typically purchased without a prescription—to a greater likelihood of future cognitive decline.

Recent international coverage highlights a potential link between certain over-the-counter antihistamines and an increased risk of cognitive decline. Leading physicians note that long-term or heavy use of first-generation antihistamines—commonly found in allergy and cold remedies—may contribute to future dementia, especially among older adults. This aligns with a growing body of evidence suggesting anticholinergic medications can affect memory and learning.

Antihistamines are a staple in Thai households, particularly as urban pollution and allergy rates rise in Bangkok and other cities. The caution matters for millions who self-medicate with OTC drugs, often without professional guidance. Thai readers should understand which medicines carry higher cognitive risks and how to choose safer options.
