A tobacco ingredient repackaged as a 'wellness' product

Claims emerge that nicotine boosts focus

Stress-relief pitch drives market expansion

Experts: little evidence for cognitive benefits

Earlier research conflates withdrawal relief with enhancement

Nicotine — long known as the addictive substance in tobacco — is being repackaged as a wellness product, with proponents touting its supposed benefits for focus, stress relief and athletic performance. Nicotine pouches, patches and products combining nicotine with caffeine or nootropics have all begun appearing on the market.

On Wednesday (local time), The Conversation, an Australian nonprofit academic and media outlet, reported that a new image of nicotine is spreading across social media, podcasts, wellness communities and technology startups, driven in part by the "Make America Healthy Again" (MAHA) movement.

Some influencers describe nicotine as a "misunderstood substance" that has been unfairly stigmatized by its association with cigarettes. Their argument: consuming nicotine without smoking can sharpen focus and productivity, reduce stress and even help ward off cognitive decline.

Claims that nicotine boosts focus and productivity have become a recurring theme in the wellness market. Some studies have suggested that nicotine may temporarily improve certain aspects of attention, alertness, reaction time and working memory, The Conversation reported.

Experts who study nicotine addiction and the health effects of tobacco and nicotine products, however, say these claims go beyond what current human research has actually demonstrated. Evidence that nicotine meaningfully enhances cognitive function in healthy people is lacking, and it may even impair performance in those who already have high baseline cognitive ability, they say.

A further factor undermining the reliability of the research is that many of the relevant studies included participants who already had nicotine dependence. Stopping nicotine use can trigger withdrawal symptoms — reduced concentration, irritability, anxiety and restlessness. Because nicotine use can then relieve those symptoms, it is difficult to determine whether the focus improvements observed in studies reflect a genuine benefit of nicotine itself or simply the resolution of withdrawal.

Some also claim that nicotine helps with stress and mood by stimulating the brain's reward circuits, producing a temporary sense of pleasure and relief.

Yet experts also note that prolonged nicotine exposure can interfere with the body's stress-response system, making anxiety and stress harder to manage over time. Multiple studies have found that people who quit smoking tend to experience reductions in anxiety, depression and stress, along with improvements in mood and quality of life.

Some corners of the wellness industry point to research suggesting nicotine can affect neural circuits involved in memory and attention. Drawing on animal studies and other findings, proponents go so far as to claim that nicotine can prevent dementia, Alzheimer's disease, Parkinson's disease and age-related cognitive decline.

Clinical research, however, has not established that nicotine prevents dementia, slows the progression of Alzheimer's disease or protects long-term cognitive function. Claims that nicotine slows biological aging or extends lifespan likewise remain confined to laboratory and animal studies.
