Recent U.S. research shows a sharp rise in cannabis use among adults 65 and older. From 2021 to 2023, use grew by about 46%, with roughly one in seven seniors reporting cannabis use in the past month. This marks a dramatic shift from two decades ago and highlights new public health considerations as societies age, including Thailand, which is watching international trends closely.

Why this matters for Thai readers lies in Thailand’s evolving stance on medical cannabis. Since legalization steps began in 2018 and continued with decriminalization in 2022, access to cannabis products has increased. As Thailand’s elderly population grows, international experience offers lessons for health care, regulation, and social norms in the kingdom.

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 study raises serious concerns about cannabis and heart health. Research led by investigators at UCSF and published in JAMA Cardiology shows that cannabis use—whether smoked or consumed as edibles—may impair cardiovascular function. The findings challenge the idea that cannabis is a safer alternative to tobacco, especially as legalization and consumer use expand globally, including in Thailand.

For Thai readers, the study arrives at a moment when policy, health messaging, and potential economic benefits of cannabis are hotly debated. Thailand has moved to legalize certain cannabis activities, creating a local landscape where public health guidance needs to keep pace with evolving regulations. The new evidence underscores the importance of clear information for patients, clinicians, and regulators.

Thailand’s health authorities are moving to restrict cannabis access to medical use only, citing rising smuggling incidents and concerns about unregulated consumption. In the next 40 days, dispensaries will be allowed to sell cannabis only to licensed medical patients and practitioners, including traditional Thai medicine healers. The plan also caps a 30-day supply for both Thai citizens and foreign visitors, reinforcing a medical-first approach to cannabis in the country.

Recent seizures, including a large 73-kilogram haul intercepted at Suvarnabhumi Airport, highlight the urgency of tightening controls. Data from Thailand indicates that cannabis findings have reached international destinations such as the United Kingdom, India, Pakistan, and Hong Kong, underscoring global pressure to curb illicit trade and prevent the nation from becoming a trafficking hub.

Thailand is poised to tighten its cannabis regulations with a plan that could require both Thai citizens and visitors to hold a doctor’s certificate to buy cannabis. The proposal, shared at a Bangkok press briefing by the Public Health Minister, signals a significant shift from Thailand’s 2022 decriminalisation. The move comes just three years after the landmark decision that put the country at the forefront of Asia’s cannabis reforms.

Data from government health authorities shows the cannabis market expanded rapidly after decriminalisation, with shops opening across major cities and tourist hubs. While the policy initially spurred agricultural growth and tourism, gaps in regulations sparked concerns about addiction, underage use, and Thailand’s international image as a “weed tourism” destination. Officials emphasise that the new rule aims to curb recreational use and ensure medical access remains the priority.

Thailand is poised to tighten cannabis regulations after a surge in cases of foreign tourists attempting to smuggle the drug out of the country. The move follows the 2022 decriminalisation of cannabis, which spurred a local boom in tourism and entrepreneurship but also sparked public concern and international scrutiny.

In 2022, Thailand became Asia’s first country to remove cannabis from its narcotics list. The policy was pitched as an economic driver for farmers and the tourism sector. Dispensaries proliferated and the relaxed stance drew cannabis-curious visitors from around the world. Yet the absence of comprehensive rules left gaps that critics say enabled underage use, addiction risks, and now large-scale smuggling.

A growing wave of fitness enthusiasts is reshaping stereotypes about cannabis and exercise. Evidence and firsthand accounts suggest cannabis can make workouts more enjoyable, helping people stay motivated and perhaps even experience a version of the “runner’s high.” In interviews with media and researchers, individuals like Mark, a father in his 40s, describe using cannabis products such as vape pens or edibles to make training more engaging. Mark says while he could complete a marathon without cannabis, the training might have felt more daunting without it.

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 landmark international study suggests medical cannabis may support cancer treatment, potentially slowing disease progression and improving quality of life for patients. Described as the largest investigation to date, the research tracked thousands of cancer patients prescribed cannabis-based medicines as part of their care. While results are encouraging, experts caution that longer, controlled studies are needed to confirm cause and effect and determine optimal dosing. Data from leading medical centers and public health researchers indicates significant relief from pain, nausea, and anxiety, alongside improvements in quality of life for some participants.

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.

A new study indicates that older adults who seek medical help for cannabis-related issues may face a higher risk of developing dementia in the following years. The findings, highlighted by major outlets and drawing on thousands of patient records, urge health professionals and policymakers to re-evaluate cannabis guidance for aging populations. In Thailand, where medical cannabis policies have evolved, the topic resonates with ongoing public health discussions about safe use and long-term cognitive health.

A Brazilian study suggests cannabidiol (CBD) may help ease autism symptoms in children and young adults. Researchers from the University of São Paulo reported that oral CBD led to improvements in social skills, fewer tantrums, and reduced aggression in participants. Presented at the 2025 European Congress of Psychiatry, the findings indicate CBD could complement traditional therapies, though experts urge larger trials to confirm results.

Interest in CBD arises from its role in supporting the body’s endocannabinoid system, which influences mood and stress. Unlike THC, CBD does not cause a high, making it a more acceptable option for neurological conditions beyond autism, such as epilepsy, while avoiding psychoactive effects.

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.
