Cigarettes are, unarguably, one of many deadliest shopper merchandise ever bought – killing round 76,000 individuals a yr within the UK and thousands and thousands worldwide.
Now, in a startling twist, the very substance that made smoking so addictive is being rebranded as a possible weapon within the combat in opposition to ageing.
A rising variety of Silicon Valley ‘biohackers’ declare that nicotine – lengthy demonised because the hook that retains people who smoke lighting up – may really sharpen the mind, suppress urge for food and even assist individuals dwell longer.
They aren’t urging individuals to smoke. As an alternative, they argue that when nicotine is stripped away from tobacco and delivered in ‘clear’ types similar to patches or oral pouches, it turns into one thing else solely: a cognitive enhancer, a metabolic stimulant, and a long life support.
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 yr 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 wish to optimise their our bodies and minds.
Critics warn this can be 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 thought 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 lengthen 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 status has been unfairly tarnished by its supply system.
‘Once I say nicotine, individuals hear smoking, as a result of the 2 are so tightly linked,’ says Mr Asprey, who was talking at an occasion organised by new nicotine lozenge model 1N. ‘However smoking incorporates 1000’s of different compounds which might be dangerous. Pharmaceutical-grade nicotine, purified nicotine, is a totally different factor.’
There may be some scientific foundation for nicotine’s cognitive results – at the least within the brief time period.
A 2021 assessment of 31 research discovered that nicotine patches considerably improved consideration in contrast with placebo. Animal research counsel 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 individuals really feel pleasure,’ says Adam Taylor, an anatomist on the College of Lancaster. ‘It additionally acts on reminiscence pathways, making individuals extra alert and bettering working reminiscence, consideration and sustained focus.’
Researchers imagine nicotine may even have longer-term protecting results. A 2018 research analysing information from greater than 200,000 individuals 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 research in mice discovered every day nicotine doses improved ‘age-associated signs’, presumably by stimulating cells concerned in DNA restore. However specialists urge warning.
‘We all know little in regards to the results of utilizing nicotine for lengthy intervals in individuals who have by no means smoked,’ says Jasmine Khouja, a psychologist and nicotine researcher on the College of Tub. ‘Nicotine will increase resting coronary heart fee, and a few proof suggests long-term publicity could harm the cardiovascular system.’
Professor Taylor provides that nicotine’s stimulant results ripple all through the physique. ‘They’ll trigger muscle twitches and spasms, palpitations, raised blood strain and disrupted sleep,’ he says. ‘These dangers are greater in individuals with present coronary heart circumstances.’
Psychological well being is one other concern. Smoking is linked to greater charges of melancholy – and switching to smoke-free nicotine doesn’t eradicate that threat solely.
‘There isn’t a stage of nicotine that may be thought-about low-risk for everybody,’ Dr Khouja says. ‘The dangers fluctuate by particular person, and we don’t but perceive them totally.
‘Nicotine merchandise will help individuals give up smoking. However for non-smokers, any cognitive advantages are prone to be short-lived and outweighed by dependancy and withdrawal.’
