Cigarettes are, unarguably, one of many deadliest shopper merchandise ever bought – killing round 76,000 folks a 12 months within the UK and tens of millions worldwide.
Now, in a startling twist, the very substance that made smoking so addictive is being rebranded as a possible weapon within the combat towards ageing.
A rising variety of Silicon Valley ‘biohackers’ declare that nicotine – lengthy demonised because the hook that retains people who smoke lighting up – may truly sharpen the mind, suppress urge for food and even assist folks reside longer.
They don’t seem to be urging folks to smoke. As a substitute, they argue that when nicotine is stripped away from tobacco and delivered in ‘clear’ kinds similar to patches or oral pouches, it turns into one thing else fully: a cognitive enhancer, a metabolic stimulant, and a long life help.
As smoking charges fall to historic lows, the marketplace for so-called smoke-free nicotine has surged. Gross sales of oral nicotine pouches alone hit £200million final 12 months and are forecast to rise by 45 per cent yearly.
And a brand new area of interest is rising on the extra excessive finish of the wellness world – ‘longevity nicotine’ – pitched at individuals who don’t smoke in any respect, however need to optimise their our bodies and minds.
Critics warn it is a harmful reframing of an addictive drug with recognized dangers. However proponents insist nicotine has been misunderstood for many years – and that its affiliation with cigarettes has obscured potential advantages.
Amongst these pushing the concept is podcaster and former Fox Information host Tucker Carlson, who runs nicotine pouch model ALP and describes nicotine as a ‘life- enhancing, God-given’ substance.
One of many loudest advocates is well being entrepreneur Dave Asprey, who describes himself because the ‘father of biohacking’ – a motion dedicated to hacking human biology to maximise efficiency and prolong lifespan.

One of many loudest advocates is Dave Asprey, who describes himself because the ‘father of biohacking’ and claims his organic age is in his late 30s
Asprey claims his organic age is in his late 30s, and that exams present his arteries resemble these of a 23-year-old.
A key a part of his routine, he says, is nicotine. For the previous 5 years, he has used round 2mg a day – one-tenth of the nicotine in a cigarette – delivered by way of a patch.
Biohackers argue that nicotine’s repute has been unfairly tarnished by its supply system.
‘Once I say nicotine, folks hear smoking, as a result of the 2 are so tightly linked,’ says Mr Asprey. ‘However smoking incorporates hundreds of different compounds which might be dangerous. Pharmaceutical-grade nicotine, purified nicotine, is a completely different factor.’
There’s some scientific foundation for nicotine’s cognitive results – at the least within the brief time period.
A 2021 evaluate of 31 research discovered that nicotine patches considerably improved consideration in contrast with placebo. Animal research recommend it is because nicotine binds to acetylcholine receptors within the mind – a part of a neurotransmitter system central to reminiscence and studying.
Activating these receptors can improve consideration, working reminiscence and sensory processing.

‘Nicotine’s speedy arrival within the mind prompts reward pathways that make folks really feel pleasure,’ says Adam Taylor, an anatomist on the College of Lancaster. ‘It additionally acts on reminiscence pathways, making folks extra alert and bettering working reminiscence, consideration and sustained focus.’
Researchers imagine nicotine may even have longer-term protecting results. A 2018 examine analysing information from greater than 200,000 folks discovered people who smoke had been considerably much less prone to develop Parkinson’s illness.
Consultants suspect nicotine performs a task. One principle is that it binds to receptors concerned in dopamine signalling – a pathway recognized to be disrupted in Parkinson’s.
In the case of ageing itself, nonetheless, the proof is skinny.
One examine in mice discovered each day nicotine doses improved ‘age-associated signs’, probably by stimulating cells concerned in DNA restore. However specialists urge warning.
‘We all know little concerning the results of utilizing nicotine for lengthy durations in individuals who have by no means smoked,’ says Jasmine Khouja, a psychologist and nicotine researcher on the College of Bathtub. ‘Nicotine will increase resting coronary heart charge, and a few proof suggests long-term publicity might injury the cardiovascular system.’
Professor Taylor provides that nicotine’s stimulant results ripple all through the physique. ‘They will trigger muscle twitches and spasms, palpitations, raised blood stress and disrupted sleep,’ he says. ‘These dangers are greater in folks with current coronary heart situations.’
Psychological well being is one other concern. Smoking is linked to greater charges of despair – and switching to smoke-free nicotine doesn’t eradicate that threat fully.
‘There isn’t any stage of nicotine that may be thought-about low-risk for everybody,’ Dr Khouja says. ‘The dangers range by particular person, and we don’t but perceive them totally.
‘Nicotine merchandise may help folks give up smoking. However for non-smokers, any cognitive advantages are prone to be short-lived and outweighed by dependancy and withdrawal.’
