How Smoking Impacts Cognitive Function and Brain Health


The human brain serves as the control center for essential functions such as cognition, memory, decision-making, and emotional regulation. Thus, maintaining optimal brain health is crucial for overall well-being and quality of life. As we discussed in a previous post titled What is Brain Health and Why Is It Important, however, various lifestyle factors, including smoking, can compromise cognitive function and predispose individuals to neurological disorders like dementia and Alzheimer’s disease.

In this article, we’ll take a closer look at the link between smoking, cognitive function, and brain health and explore strategies for quitting smoking to preserve cognitive well-being.

The relationship between smoking, cognitive function, and brain health

Mounting evidence from neuroscientific research shows that smoking has harmful effects on cognitive function and brain structure. For example, in one study from the Washington University School of Medicine, researchers found that smoking shrinks the brain, putting smokers at higher risk of Alzheimer’s and dementia. Furthermore, the association between smoking and brain volume depended on dose: The more packs a person smoked per day, the smaller his or her brain volume.

Moreover, chronic smoking has been associated with cognitive deficits, including impaired attention, memory, executive function, and processing speed. According to a research article published in the BMC Public Health journal, these impairments appear to manifest very early in smokers, as demonstrated in the inferior working memory of young adults with a mean of only four years of smoking. Some studies have attributed cognitive deficits to the build-up of metals found in cigarette smoke, such as iron, copper, and zinc. Meanwhile, other studies indicate that smoking creates changes in white matter lesions on the brain, which further contribute to cognitive decline and accelerate brain aging.

While some of the effects of smoking on brain health, like decreased brain volume, are irreversible, experts note that smoking remains a modifiable risk factor for further cognitive decline. By quitting, smokers can slow the acceleration of brain aging, reduce the risk of dementia, and preserve brain health.

How to quit smoking and preserve brain health

One of the biggest barriers that smokers may face on their cessation journey is nicotine addiction. Fortunately, there are various strategies that can facilitate smoking cessation and support cognitive recovery. Among the most effective approaches for quitting is through the use of smoking alternatives, such as nicotine pouches and nicotine replacement therapies (NRTs).

Nicotine pouches offer a smokeless and discreet way to deliver nicotine without the harmful toxins present in tobacco smoke. These pouches, which are placed between the cheek and gums, release nicotine gradually, alleviating cravings and withdrawal symptoms. As smokers transition away from combustible tobacco, nicotine pouches can serve as a bridge to cessation, allowing individuals to gradually reduce nicotine dependence while preserving cognitive function.

For smokers interested in exploring nicotine pouches as a smoking alternative, Prilla offers a diverse selection of brands, strengths, and flavors. Through the website, smokers can browse and purchase pouches from popular brands like ZYN, VELO, and On!, which carry coffee, citrus, and mint-flavored nicotine pouches.

In addition to nicotine pouches, over-the-counter NRTs, including nicotine lozenges from Dr. Reddy’s Laboratories and Habitrol, are readily available at pharmacies and provide alternative sources of nicotine. Similar to pouches, NRTs help manage cravings during cessation. Dr. Reddy’s nicotine lozenges come in 2mg and 4mg doses so that users can tailor their consumption according to their level of dependence.

The detrimental effects of smoking on cognitive function and brain health underscore the importance of tobacco cessation. By adopting smoking cessation strategies and leveraging smoking alternatives, individuals can safeguard their cognitive well-being and embark on a path toward a healthier future.
