“Nicotine might actually be good for you.”
A decade ago, that sentence would have got you mocked at. However, things seem to have changed now. You don’t dismiss the claim at a glance. Why? Because we live in an era where old health beliefs are constantly being challenged and every few weeks the internet discovers a new hack for better health.
So, when nicotine begins showing up in conversations about cognitive performance and longevity, curiosity is almost inevitable. Because, even if the internet gets you a new breakthrough in science first, it feels normal.
Earlier, nicotine was associated with discussion around smoking and anti-tobacco warnings. Today, there are several videos online claiming that nicotine may not be the villain we once thought it was. There’s probably more to its use and benefits.
But is it?
The wellness claim on nicotine
Several wellness influencers are at the helm of this discourse on social media, where they claim it can help boost memory function, concentration and cognitive performance.
Dave Asprey, an American entrepreneur and popular biohacker, is one of them. In several podcasts and interviews, he has shared how the isolated use of nicotine, in small amounts, can actually have certain cognitive benefits.
Following suit, more wellness influencers on social media started talking about the same, arguing that nicotine has been vilified far beyond reason.
It all started a while back and versions of these claims keep circulating across podcasts, Reddit threads and wellness forums, often backed by references to neuroscience studies, longevity research and sharper focus.
While the claims sound compelling, they often leave out an important distinction: nicotine is not the same thing as smoking, but neither does that automatically make it a wellness supplement.
Naturally, we turned to experts in the field to unpack the truth.
Reality check
Nicotine replacement products (NRTs), such as gums and patches, have long been used to help people quit smoking. That’s because nicotine itself is not considered the main cancer-causing substance in cigarettes. Instead, the biggest health risks come from the thousands of harmful chemicals released when tobacco is burned, including several known carcinogens.
Nicotine’s role is different — it’s the ingredient that keeps people hooked. And that is also part of the problem.
At its core, nicotine acts like a chemical messenger. Once it reaches the brain, it sparks the release of compounds linked to pleasure, alertness and mood. It also taps into pathways that help regulate attention and memory, which helps explain why some users report feeling more focused after consuming it.
“Nicotine can temporarily improve alertness and attention by stimulating nicotinic receptors in the brain. Calling it ‘healthy’ is misleading,” Dr. Lancelot Pinto, consultant pulmonologist and epidemiologist, P. D. Hinduja Hospital and Medical Research Centre, Mahim, tells India Today.
He further explains, “Research shows modest short-term improvements in attention and working memory, particularly in nicotine-naive individuals. The molecule may have neuroprotective effects against cognitive decline, but these are results from association studies and remain speculative, with no early degree of certainty.”
Unlike time-tested stimulants such as caffeine, nicotine is highly addictive and increases cardiovascular stress, putting vulnerable individuals, especially young adolescents, at greater risk.
And that is why experts do not recommend it as a brain booster.
Even where research hints at short-term cognitive effects, specialists say there are numerous safer ways to sharpen the mind — from puzzles and critical-thinking exercises to learning new skills and staying physically active. When it comes to improving brain health, nicotine isn’t a recommendation you’ll hear from them.
Adding to this, Dr. Mihir Gangakhedkar, consultant – pulmonology, Fortis Hospital Mulund, Mumbai, asserts, “Research is limited to research subjects. It cannot be generalised until it has been tested adequately. There is no cognitive-enhancement message for the public as yet that can be declared as such.”
Social media versus science
And the urge to have quick fix is where people miss science.
Dr. Gangakhedkar doesn’t mince words when it comes to social media’s role in shaping health narratives. According to him, viral posts often spotlight eye-catching, cherry-picked claims while glossing over the nuances that matter.
“They (influencers) are getting technically nothing right. It is a chemical with significant addictive potential.” Over time, users can also build up a tolerance to nicotine and become addicted, eventually struggling to concentrate without it.
“There is no regulation per se on nicotine, given that gums and patches are freely available on the market. But one must understand that the intention behind making them accessible is tobacco cessation. It is unfortunate if the message conveyed through social media replaces the strict scientific rigour required for the acceptable use of products with possible harm,” he adds.
According to Dr. Pinto, all of this reflects the broader “biohacking” culture.
“Such “hacks” do not need to undergo the rigorous testing that drugs do, and the liability for those selling such products is negligible, making it a prime space for the exploitation of vulnerable individuals.”
While the medical experts do agree that there are studies and research pointing out the cognitive benefits of nicotine, the scope is limited. According to them, there is not enough evidence yet to properly recommend nicotine as a way to improve brain health.
Takeaway
In many ways, the conversation isn’t really about nicotine. It’s about our growing appetite for shortcuts.
From supplements and nootropics (cognitive enhancers) to cold plunges and productivity hacks, modern wellness is full of promises to help us think faster, feel better and perform more. Nicotine is simply another entrant in that long line of fixes.
Experts agree on one thing that health trends often move faster than the science behind them. Nicotine may be having a moment in certain corners of the internet, but that doesn’t automatically make it the next wellness breakthrough.
So, is nicotine the wellness world’s most misunderstood compound or simply its latest obsession?
Experts lean towards the latter. While science continues to evolve, they say one thing is already clear: a few intriguing findings are not the same as a green light.
