The latest findings from US-based research show that marijuana use among seniors has surged to unprecedented levels, sparking both celebration and concern within the medical community. According to multiple 2025 reports and studies, the rate of cannabis use among adults aged 65 and older rose by nearly 46% from 2021 to 2023, with approximately one in every seven seniors now reporting cannabis use in the past month. This dramatic shift, up from just 1 in 100 twenty years ago, reflects not only changing generational attitudes towards cannabis but also signals new public health challenges and opportunities for societies embracing an aging population—Thailand included (Axios, FOX News, WGAU Radio).

A new wave of scientific concern is cresting over cannabis use, as recent research finds that using marijuana—whether smoked or eaten in gummies—is directly associated with significant risks to heart health. The findings, published in JAMA Cardiology and led by researchers at the University of California, San Francisco (UCSF), upend the common belief that cannabis is a safer or even harmless alternative to tobacco, particularly as legalization and recreational use continue to rise worldwide, including in Thailand.

A new wave of fitness enthusiasts is challenging the long-standing stereotype of the “lazy stoner,” as growing evidence—and candid testimony—suggests that cannabis is helping people exercise, find joy in workouts, and perhaps even unlock their own version of a “runner’s high.” As recently reported by Yahoo! News, and supported by emerging research, people like Mark, a father in his 40s, are using cannabis products such as vape pens or edibles to make their training more enjoyable and less monotonous. Mark credits cannabis with helping him complete the demanding months of training for his first marathon, saying, “I definitely could have run the marathon without the marijuana, but I don’t know how easily I could have completed the training without it” (Yahoo! News).

A groundbreaking new study has added weight to the growing evidence that medical cannabis could play an important role in the fight against cancer, capturing international attention this week. The research, described as the largest-ever investigation into medical cannabis and cancer outcomes, found that certain cannabis-based medicines may help slow disease progression and improve quality of life for people diagnosed with cancer. Published results have sparked hope among patients, clinicians, and medical researchers globally—including in Thailand, where conversations around both cannabis regulation and cancer care remain highly relevant.

A recent study published this week has found that older adults who seek medical help for cannabis use may face a significantly higher risk of developing dementia, highlighting urgent concerns as marijuana use rises among aging populations worldwide—including here in Thailand. This research, first reported by The New York Times, observed a meaningful connection between cannabis use disorder and subsequent dementia diagnosis in individuals aged 55 and older, prompting both health professionals and policymakers to re-examine guidelines and public health messaging regarding cannabis, especially in countries like Thailand that are reconsidering their cannabis policies.

In an exciting development, a Brazilian study has highlighted cannabidiol (CBD) as a potential supplement in easing autism symptoms in children and young adults. Researchers from the University of São Paulo have found that oral CBD intake led to significant improvements in social skills, reduced aggression, and eased tantrums among young participants. This promising research, presented at the 2025 European Congress of Psychiatry, suggests that CBD could be incorporated into autism treatment plans alongside traditional therapies. However, experts remain cautious, calling for larger trials to confirm these findings.
