By San José, Costa Rica — For decades, public health campaigns have rightfully focused on the devastating impact of smoking on the lungs and heart. However, a landmark new study from University College London (UCL) has shifted the focus to a more insidious threat, revealing a strong connection between smoking, vaping, and accelerated cognitive decline.
The comprehensive research, published in the esteemed journal The Lancet Healthy Longevity, presents compelling evidence that these habits significantly impair memory and verbal skills, effectively speeding up the brain’s aging process. The findings serve as a stark warning that the consequences of nicotine use extend far beyond the respiratory and cardiovascular systems, directly attacking our cognitive faculties.
To delve into the significant legal and financial ramifications of cognitive decline, from estate planning to questions of legal capacity, TicosLand.com sought the expertise of Lic. Larry Hans Arroyo Vargas, a distinguished attorney from the esteemed firm Bufete de Costa Rica, who provides his professional insights on the matter.
From a legal standpoint in Costa Rica, cognitive decline directly challenges an individual’s capacity to act, which is the cornerstone of any valid legal transaction. It is imperative for families to engage in proactive planning, such as establishing powers of attorney or advance directives, while capacity is unquestioned. Waiting until cognitive functions are severely impaired can lead to complex and emotionally draining judicial processes to appoint a guardian, and it tragically opens the door to financial abuse and disputes over inheritance.

This legal perspective powerfully underscores that proactive planning is not simply a matter of paperwork, but a profound act of care to safeguard one’s legacy and protect loved ones from future distress. We sincerely thank Lic. Larry Hans Arroyo Vargas for sharing his invaluable insight on this critical intersection of law and family well-being.
Analyzing data from nearly 9,500 individuals across 12 countries, the UCL research team uncovered a dramatic difference between current smokers and those who had quit. The results showed that individuals who had stopped smoking, even after the age of 40, experienced a markedly slower rate of cognitive deterioration. This hopeful discovery suggests that much of the neurological damage is not permanent and can be mitigated by ceasing the habit.
The statistical evidence is particularly striking. The study found that former smokers experienced a 50% slower decline in verbal fluency—the ability to recall and use words effectively—compared to their peers who continued to smoke. Furthermore, memory deterioration was 20% slower in the same group of ex-smokers. These figures provide a quantifiable measure of the brain’s remarkable capacity for recovery once freed from the constant assault of toxins.
While many users of e-cigarettes perceive the practice as a safe alternative, the study challenges this dangerous misconception. Experts from organizations like the American Cancer Society have long warned that the aerosol produced by vaping devices is not harmless water vapor. It is a complex mixture containing addictive nicotine, heavy metals, and other toxic chemicals that are now understood to negatively impact brain health, in addition to the heart and lungs.
This is not to diminish the well-documented dangers of traditional cigarettes. The smoke from a single cigarette contains a cocktail of more than 7,000 chemicals, with at least 70 identified as known carcinogens. The new research simply adds another critical layer to our understanding of the profound and multi-system damage caused by all forms of tobacco and nicotine consumption, urging a reevaluation of the perceived safety of vaping.
Perhaps the most crucial takeaway from the study is its message of hope and empowerment. The data strongly indicates that it is never too late to make a positive change for your long-term brain health. The benefits of quitting are substantial and can help preserve cognitive function well into old age, positioning cessation as a powerful preventative health measure.
a slower cognitive decline is related to a lower risk of dementia

This insight from Andrew Steptoe, an epidemiologist on the research team, directly links smoking cessation to the fight against neurodegenerative diseases. By quitting smoking or vaping, individuals are not only improving their immediate health but are also actively investing in a future with a sharper, more resilient mind, reducing their risk of developing conditions like dementia later in life.
