Key Takeaways

  1. Nicotine has been used for thousands of years for its nootropic properties such as improving concentration, memory, motivation, and mood.
  2. As a nootropic, nicotine is typically dosed at 1 – 2 mg
  3. Despite the cognitive benefits of nicotine, it is not recommended to smoke tobacco due to the harmful effects.
  4. Nicotine can be addictive and cause side effects like increased heart rate, high blood pressure, gastrointestinal problems, and it may promote tumor growth, so its use requires caution.


Nicotine (3-(1-Methyl-2-pyrrolidinyl) pyridine) is an alkaloid found in tobacco leaves. And has been used by humans for its psychoactive (nootropic) properties for thousands of years.

But it is only in the last several decades that nicotine’s mechanism of action in the brain has been revealed.

Nicotine works primarily by upregulating nicotinic acetylcholine receptors (nAChR) in the brain. Increasing neural signaling of neurotransmitters and boosting alertness, cognition and memory.

Studies have shown however that this upregulation of nAChR is dose dependent. And too much nicotine desensitizes these receptors.[i] So low doses of nicotine are key in using nicotine as a nootropic for cognitive benefit.

Since we’re investigating nicotine as a nootropic here, it’s important to point out that I am not encouraging smoking. Smoking tobacco has been shown to increase cognition.

But the harmful effects of tobacco have been proven extensively.[ii] Including this study that showed life-time smokers have less gray matter in the prefrontal cortex compared to non-smokers. Affecting the brain’s reward, impulse control and decision-making circuits.[iii]

Nicotine as a nootropic helps:

  • Memory. Nicotine improves short and long-term memory. Nicotine affects nicotinic receptors which increases the use of neurotransmitters that helps with memory formation. And induces long-term potentiation which helps encode long-term memories.
  • Neurotransmitters. Nicotine binds to nicotinic acetylcholine receptors in the brain. Boosting the release of acetylcholine (ACh), dopamine, serotonin, and glutamate. Affecting alertness[iv], attention, cognition, memory and mood.
  • Brain Optimization. Nicotine modulates the connectivity and structure of brain networks. And improves whole-brain communication efficiency. Boosting overall cognitive and brain function.[v]


Nicotine (3-(1-Methyl-2-pyrrolidinyl) pyridine) is an alkaloid found most famously in tobacco leaves. But nicotine is also present in very small amounts in plants from the Solanaceae or nightshade family including potatoes, tomatoes and eggplant.[vi]

nicotine as a nootropic improves whole-brain communication efficiency


Nicotine acts on acetylcholine (ACh) receptors in your brain. Stimulating and regulating the release of a host of neurotransmitters including serotonin, dopamine and norepinephrine.

New drugs derived from nicotine and the research on nicotinic receptors are in clinical trials for Alzheimer’s, ADHD, anger management, anxiety, depression, schizophrenia, Tourette Syndrome and wound healing.[vii]

As a nootropic, we’re talking about using a nicotine lozenge or gum for cognitive function enhancement. I am NOT talking about smoking tobacco.

Smoking is the cause of 5 – 6 million deaths per year. Affecting 18 different organs in your body. But it’s not the nicotine in tobacco that kills.

The biggest issue with using nicotine as a nootropic is that it can be addictive. But it’s not the nicotine that causes cancer. Nicotine however could be a “tumor promoter”.

Nicotine binds specifically to the nicotinic acetylcholine receptor (nAChR) in your brain. And it deregulates essential processes like regulation of cell proliferation, apoptosis (programmed cell death), migration, invasion, angiogenesis, inflammation and cell-mediated immunity of stem cells, adult tissues and cancer cells.[viii]

As a nootropic, taking nicotine in smalls doses (i.e. 1-2 mg) and used occasionally helps when you need that cognitive boost. If you have cancer or a tendency to tumor growth you should avoid using nicotine.

nicotine improves mental clarity

How does Nicotine work in the Brain?

Nicotine boosts brain health and cognitive function in several ways. But two in particular stand out.

  1. Nicotine boosts memory. Nicotine binds to presynaptic nicotinic acetylcholine receptors in the brain. And boosts the release of acetylcholine (ACh), dopamine, serotonin, and glutamate.[ix] Neurotransmitters known to be involved in cognitive processes.

Problems with cholinergic signaling has been implicated in neurologic disorders including schizophrenia, ADHD and addiction. And much of the study of nicotine’s effects on cognition has been done looking for treatments for these disorders.[x]

The National Institute of Drug Abuse conducted a meta-analysis of 41 double-blind, placebo-controlled studies between 1994 and 2008. The analysis found significant positive effects of nicotine on fine motor performance, alertness, attention and accuracy, response time, short-term and working memory.[xi]

  1. Nicotine improves attention. Attention deficits are often associated with those dealing with ADHD. The inability to focus can cause all kinds of problems both in relationships, and on the job.

Nicotine has been shown to improve attentiveness in smokers. And helps alleviate attention deficits in Alzheimer’s Disease, schizophrenics and adults with ADHD.

A double-blind study conducted at Duke University Medical Center used nicotine patches to see if it would improve attentiveness in non-smoking adults without attention deficits. Subjects received 7 mg of nicotine per day using a transdermal patch for a 4 ½ hour morning session.

Nicotine significantly decreased the number of omission errors during testing. And in this study, decreased the variance in “hit reaction time” which is used a measure of attentiveness.

The study showed that nicotine reduced attention deficit, and even improved attentiveness in normal adult non-smokers.[xii]

How things go badNicotine as a nootropic improves memory

As we get older, our brain chemistry and energy metabolism changes.[xiii]

↓ Acetylcholine signaling in the brain declines

↓ Dopamine, norepinephrine, epinephrine and serotonin levels decline

↓ Alertness, attention and memory declines

↑ Anxiety, depression and stress increases

All of these age-related changes are contributing factors to the neurodegenerative diseases of aging, including Alzheimer’s and dementia.

Nicotine benefits

Nicotine boosts levels of dopamine, epinephrine (adrenaline), norepinephrine and serotonin. And human cell lines in test tube studies as well as animal studies show nicotine stimulates the growth of new blood vessels. Even increasing the number of red blood cells.Nicotine as a nootropic improves alertness

Nicotine rapidly crosses the blood-brain barrier. Within 20 seconds of putting a nicotine lozenge under your tongue. It has the fastest action of any nootropic I have reviewed here on Nootropics Expert.

Alpha brain waves increase with nicotine which provides a relaxed state associated with super-learning, flow states and joy.[xiv]

Nicotine stimulates electrical and neurotransmitter activity throughout your brain. Helping alertness, mood, motivation, selective attention, sustained attention, and decreases distraction.[xv]

Nicotine helps pre-attentional processing which is your ability to detect information. It brings you down when you’re up. And it brings you up when you’re down. And it helps you cope with stress and anxiety.

And nicotine improves short-, long-, and working memory processes.[xvi]

How does Nicotine feel?

Neurohackers report nicotine improves mental clarity and motivation. Mood swings are minimized and less anxiety.

Concentration and focus significantly get a boost with nicotine as a nootropic.

All forms of memory get a boost with nicotine. Short and long-term memory. And working memory. Nicotine induces long-term potentiation in the hippocampus which is the basis for the neuroplasticity that helps encode long-term memory.[xvii]

The key with nicotine is to use low doses. And only use it occasionally. Too much nicotine desensitizes the alpha-7 nicotinic acetylcholine receptor. So tolerance is an issue. But your receptors recover fairly quickly if you give them a break for a day.

nicotine as a nootropic boosts cognition

Nicotine Clinical Research

Much of the research conducted with nicotine was done with cigarette smokers. The studies were to determine the effects of abstinence (quitting smoking) on cognition. Or funded by tobacco companies out to prove smoking was good for you (i.e. improved cognition). Cigarette smoke is harmful.

So keep an open mind when reviewing these studies. My intent is certainly not to encourage smoking. But to show the effects of nicotine regardless of the delivery system to the human brain.

Nicotine boosts IQ

Researchers in New Zealand conducted a trial with 10 women and 6 men ranging in age from 18 – 32 years. All participants were smokers and were instructed not to smoke during the 2-hour period prior to the experiment.

Each subject completed the even and odd numbers of the Raven’s Advanced Progressive Matrices (APM) test in two sessions. APM is a test to measure intelligence (IQ).

In each of 2 experimental sessions, subjects were given 20 minutes to complete the assigned half of the APM. Before beginning the test, subjects took 6 puffs of a medium (0.8 mg) cigarette every 20 seconds. After 10 minutes, subjects were prompted to take 2 additional puffs.

Results of the experiment showed that APM scores were significantly higher in the smoking session compared to the non-smoking session. Suggesting that nicotine acts to enhance intelligence.[xviii]

Another study at the University of Colorado may explain part of this boost in IQ. Nicotine was found to increase the efficiency of neural communication between areas of the brain involved in cognition. And even the rest of the brain.[xix]

Nicotine improves typing speed

Nicotine increases typing speedResearchers conducted 5 experiments to study the effects of using 2 mg of nicotine on keyboard typing speed. In study after study nicotine produced a reliably consistent increase in typing speed.[xx]

Nicotine will also improve and increase the speed of your handwriting. Scientists in Germany noted that nicotine has consistently been shown to improve psychomotor performance. So they recruited 38 smokers and 38 non-smokers to participate in a study.

Both groups received gum containing 0, 2 or 4 mg of nicotine. And their handwriting performance was assessed after they chewed the nicotine gum. Subjects were asked to perform a simple writing task. Movement time, velocity and acceleration of handwriting movements were measured.

Nicotine reduced movement times, increased writing velocity and more fluid handwriting movements were observed. The results suggested that nicotine can enhance psychomotor performance to a significant degree in a real-lie motor task.[xxi]

Nicotine boosts memory

Nicotine has been shown to improve short-term and working memory in several studies. In this study conducted in the UK, researchers recruited 60 smokers and 60 non-smokers in a double-blind procedure.

Half of the subjects chewed nicotine gum and the other half chewed a placebo prior to performing a memory task. Results showed that nicotine significantly improves short-term memory.[xxii]

Nicotine for the treatment of ADHD

Several studies have shown the benefits of nicotine in treating the symptoms of ADHD. Focusing and memory break down in those of us with ADHD and ADD. And treatment with Ritalin, Adderall or other stimulants often corrects this inattentiveness and memory impairment. But it does nothing for the accompanying depression and anxiety.

And this is the reason many Adult ADHD sufferers smoke. This study showed that using a nicotine patch not only helped decrease anxiety and depression symptoms of ADHD. It also helped smokers stop using tobacco products while taking care of their ADHD symptoms.[xxiii]

In this study, nicotine was compared to the effects Ritalin and or a placebo had in treating ADHD. Nicotine improved performance and reduced errors. It decreased depression, and decreased overall severity of ADHD symptoms.[xxiv]

Another double-blind, placebo-controlled trial worked with 6 smokers and 11 nonsmokers with Adult ADHD. Nicotine decreased ADHD symptoms, increased vigor, and improved reaction time.[xxv]

Nicotine Recommended Dosage

Nicotine as a nootropic is dosed at 1 – 2 mg on an as needed basis.

Nicotine gum typically comes in 2 – 4 mg. You can cut a 4 mg piece of gum in half for a 2 mg dose. Gum releases the nicotine dose over the course of 20 – 30 minutes.Nicotine recommended dosage

The problem with nicotine gum is aspartame along with other unhealthy sweeteners.

Nicotine patches come in varying strengths and usually contain more nicotine than gum or lozenges. Neurohackers (contrary to package warnings) cut the patch to size depending on the dose they want to use.

My preferred method is nicotine lozenges. Mini-lozenges are best because they’re not full of toxic chemicals like larger lozenges. The 2 mg mini-lozenge cut in half provides cognitive benefits within 10 – 20 minutes.

Nicotine Addiction & Other Side Effects

Nicotine is addictive primarily because it boosts levels of dopamine in your brain.[xxvi] Not nearly as addictive as smoking tobacco or chewing tobacco but addictive nonetheless.

Nicotine can cause increased heart rate, high blood pressure, dizziness, cough, sneezing, sinus problems, upset stomach, constipation, and headaches.

Nicotine does not “cause” cancer. But may be a tumor promoter. So if you had or currently have cancer you should avoid nicotine.

If you are dealing with a gut infection of H pylori bacteria, you should not use nicotine until you get this problem under control.

Type of Nicotine to buy

Nicotine used as a nootropic comes in gum, inhalers, lozenges, and transdermal nicotine patches.

See “Nicotine Recommended Dosage” for specific dosing instructions.

Nicotine Gum & Lozenges

Mini-lozenges are the safest and best form for nootropic use. I have tried and recommend the nicotine lozenges or gum by Lucy Nicotine. Lucy uses pharmaceutical grade nicotine and natural ingredients only in their lozenges and gum. Check them out here: Nicotine.

Nicotine Spray

Nicotine spray is a newer option you may want to try. You get a 1 mg dose for each spray under your tongue (sublingually). Great for a quick cognitive boost and burst of energy. There’s about 100 sprays in each container.

Nicotine Vaping

Vaping is another option. But it can come with a host of potential issues if you’re not familiar with vaping. The safest option is rebuildable coils using stainless steel wire and organic cotton with vegetable glycerin as your nicotine base. And keeping the temperature low and power less than 4 volts.

Of course there is also cigarette smoking and chewing tobacco for your nicotine dose which I DO NOT recommend.

Nootropics Expert Recommendation

Nicotine 1 – 2 mg per dose

Nootropics Expert Tested and ApprovedI recommend using Nicotine as a nootropic supplement.

Your body does not make nicotine on its own. So if you are going to supplement with nicotine, you must take it as a supplement.

Nicotine is helpful for those dealing with short-, long-term and working memory problems, low energy, depression or anxiety.

Nicotine is especially helpful for dealing with the symptoms of Adult ADHD. Nicotine can help relieve many of the symptoms of ADHD. And is a good compliment to your existing ADHD meds.

While nicotine is a powerful cognitive enhancer, it is also addictive and can lead to tolerance and withdrawal symptoms in some people. So caution is advised. And if you’re prone to addiction please stay away from nicotine as it can lead to nicotine addiction.

As neurohackers, we have great acetylcholine agonists available to us if you don’t want to experiment with nicotine. Most of the racetams will boost acetylcholine use in the brain.

We suggest starting with a dose of ½ – 1 mg of nicotine in mini-lozenge or spray form. Nicotine will compliment nearly everything in your current nootropic stack.

There is no benefit to dosing more than 2 mg of nicotine for cognitive benefit. And too avoid addiction and tolerance we suggest only using nicotine occasionally. for example sells nicotine 4mg lozenges. Use a pill splitter and cut them in half for a 2 mg nootropic dose.

Hi. I have ADHD. Non medication needed just CBT but sometimes I need a 2 mg lozenge cut in half twice a day to function. Not placebo at all and feel focused, relaxed and so what grounded.
Is this ok to take everyday?
Or do you recommend a few days off?
I do seem to be more part of the family thing when doing so… Not being busy and hyperfocus.
Thoughts please.

    David Tomen
    June 12, 2023

    Bob, use nicotine “as needed”. Days off are not needed. But too high a dose or too often and you desensitize the very receptors you are trying to influence.

      June 13, 2023

      Thanks. So is a 2mg lozenge more than enough?

        David Tomen
        June 16, 2023

        Bob, a safer dose is 1 mg nicotine. 2 mg is not overdosing but if used too often can desensitize nicotinic acetylcholine receptors which we are trying to influence by using nicotine.

June 2, 2023

What about white pouches? These seem to have all the benefits, and leave behind the legacy of Snus or chew.

    David Tomen
    June 5, 2023

    Owen I am not familiar with “white pouches”. But nicotine is nicotine. Just be aware that dosing 1 – 2 mg on an as needed basis is all you should be using. Because higher doses end up desensitizing the same receptors you are trying to activate.

May 31, 2023

Hi Dave! Thanks for all the great information. I have been using a 14mg patch cut into 4 pieces and putting one on every 24 hours. I started bc I have heard that the spike protein binds to the nicotine receptors and that if you take nicotine, you will feel better. I did not have long COVID, but I had the virus so I figured I would try nicotine…couldn’t hurt. What I have noticed is that I am sleeping so much better and I am dreaming…which I never dream (or if I do, I never remember them) I was wondering if you have heard this from anyone else?

    David Tomen
    June 5, 2023

    Sandra, I suggest you scroll up and read the entire review above because it explains the benefits you are feeling from using nicotine.

May 4, 2023

Excellent article, David. I use the Lucy gum once or twice a day for two purposes: (1) tackling tough cognitive challenges (I’m a lawyer, so the cognitive challenges come fast and furiously); and (2) hard exercise sessions (I’m a competitive powerlifter, and I find I can “attack” the bar weights if I work out while chewing the Lucy gum).

Your article suggests I could get the same effect from a half-dose of the Lucy gum (i.e., 2 mg). Is that correct?

Thank you!

    David Tomen
    May 5, 2023

    Michael, that is correct because too much nicotine quickly desensitizes nicotinic acetylcholine receptors.

April 17, 2023

Hi David.
I just started taking a 2mg nicotine lozenge once daily
I noticed I get a slight headache.
Is this because I am not having enough choline or is the dose just too high for me?

    David Tomen
    April 18, 2023

    George, the dose is too high. For nootropic usage it is 0.5 mg.

February 2, 2023

David, do you think you could discuss the vaping option a bit more?

I have been on and off (split) nicotine gums and (cut) patches, 1-2mg at max per day over 8 years and mainly for work. Did not develop an addiction but also used it rather sparingly (rarely daily), with many months-long gaps. I find 1-2mg still to be a bit too much for an otherwise non-smoker, and I feel this also builds up tolerances fairly quickly.

Vaping has a few advantages:
* smaller doses: a container has 2mg and a couple of hundred drags, my current e-cig delivers 0.008mg at 500 drags
* unlike nicotine gums no throat burn or upset stomach
* unlike patches no constant delivery
* you don’t have to “finish” it, if used sparingly the 2mg can last weeks
* you can vary the smoking method, e.g. not inhale to the lungs

On the other hand, the FDA has labeled vaping as controversial after the producers targeted their marketing on young people, which I would agree with. Nicotine still has the addictive potential – you can become addicted to the process of vaping. And many manufacturers are putting dubious substances into the liquids.

Would be curious about your opinion here.

Thank you for your highly useful and informative website.

    February 3, 2023

    Kath, vaping seems the ‘safer’ choice if you do not want to use mini lozenges, gum or patches. But the jury is still out on how safe vaping really is. It certainly is not as harmful as smoking tobacco. But logic says that when you heat things like propylene glycol and flavorings to high temps then it cannot be a good outcome.

November 6, 2022

Hi David, I bought 3 pack Lozenges from nicotine 4mg, but I’m afraid they expire in a month and I won’t be able to finish them so quickly, I would like to know your opinion please, not as a medical recommendation, about what is the worst thing that can happen from consuming this product after expired?, and finally do you think it is still effective after 6 months expired?

    David Tomen
    November 7, 2022

    Bob, nicotine in products tends to decrease with age. Best to store them in a cool place like the fridge and in a sealed bag. The worst that can happen if a lozenge is used beyond the expiration date is it may not be as effective.
