  • Nicotine gum

    Nicotine gum

    For decades, nicotine replacement therapy (NRT) has been helping smokers quit. Nicotine gums are designed to treat physical dependence on nicotine by releasing a controlled dose through the oral mucosa, thus avoiding the thousands of harmful chemicals present in tobacco smoke and reducing cravings and other nicotine withdrawal symptoms.

    What is Nicotine Gum and How Does It Work?

    Nicotine gum is exactly what its name implies: a piece of specially formulated chewing gum containing medicinal nicotine. Unlike regular chewing gum, it is designed to be “parked” between the cheek and the gum after a few chews, allowing the nicotine to be absorbed slowly into the bloodstream. This process helps to smooth out the craving cycles that derail many quit attempts. The active ingredient, nicotine, is present in a polacrilex resin that controls its release. The gum often contains flavorings, sweeteners, and buffering agents to facilitate absorption and manage taste.

    Crucially, the gum’s approval extends beyond simply quitting cold turkey. It is also sanctioned for smoking reduction, allowing highly dependent smokers to cut back their cigarette consumption before fully stopping, and for pre-treatment (or ‘pre-quitting’), where users start the gum a week or two before their target quit date to lower their dependence baseline, thereby increasing the chances of success when the final stop occurs.

    Dosage: The Critical Difference Between Success and Relapse

    The efficacy of nicotine gum hinges on using the correct strength and quantity. It is available in two main dosages: 2 mg and 4 mg. The choice between these is directly tied to the individual’s level of nicotine dependence, which is typically measured by the time elapsed between waking up and smoking the first cigarette.

    Smokers who light up their first cigarette more than 30 minutes after waking are generally advised to start with the 2 mg dose. However, those who smoke their first cigarette within 30 minutes of waking, or who smoke more than 20 cigarettes per day, should begin with the 4 mg strength.

    This emphasis on starting with an adequate dose is vital because underdosing is a primary reason for treatment failure. If the nicotine supply is not enough to counteract the withdrawal symptoms—such as irritability, anxiety, intense cravings, and lack of concentration—the smoker’s brain will signal an overwhelming need for a cigarette, often leading to a quick return to tobacco. Healthcare providers often recommend chewing a piece every hour or every 90 minutes initially, or whenever an intense craving strikes, with a typical limit of 15 to 20 pieces per day. The nicotine gum should be chewed slowly for about 30 minutes, alternating between chewing and placing it between the cheek and teeth (“chew and park”).

    Duration

    The treatment is not meant to be indefinite. A standard course of treatment is about 12 weeks, followed by a gradual reduction. For instance, the user might gradually decrease the total number of pieces chewed per day over several weeks until they are no longer using the gum at all. It is paramount that users do not stop treatment prematurely. Stopping too soon, perhaps out of a false sense of security after a few weeks of success, exposes the person to the full force of lingering cravings and other nicotine withdrawal symptoms, dramatically increasing the risk of relapse. Some individuals may benefit from remaining on the gum for six months or more, as the small, controlled nicotine exposure is infinitely safer than returning to combustion.

    Side effects

    Side effects are usually mild and related to improper chewing technique. Chewing too fast can release too much nicotine at once, leading to minor stomach upset, hiccups, or a slight burning sensation in the mouth.

    Special Populations and Public Health Impact

    Nicotine gum is contraindicated for children under the age of 12.

    Regarding pregnancy and breastfeeding, the general consensus is that while no nicotine product is entirely risk-free, the use of NRTs—including gum—is overwhelmingly safer than continued smoking. The carbon monoxide and thousands of toxins in smoke pose a massive risk to the fetus and infant, whereas NRT provides pure nicotine in a controlled manner. Use during pregnancy and breastfeeding should always be under medical supervision.

    In the broader context of public health, NRTs like the gum represent the gold standard of tobacco harm reduction (THR). They are fundamentally distinct from the controversial use of nicotine delivery systems like e-cigarettes or heated tobacco products, as they are tested, regulated pharmaceuticals with decades of data proving their safety and efficacy for smoking cessation or reduction. The gum’s role is to help people sever the link between nicotine and the lethal practice of inhaling smoke.

  • The amount of nicotine in cigarettes

    The amount of nicotine in cigarettes

    Many people know that nicotine makes cigarettes addictive, but few know how much nicotine is actually in a cigarette, or how much nicotine your body absorbs when you smoke. Understanding these numbers can help you choose an alternative product that does not involve burning tobacco or inhaling smoke.

    How much nicotine is in a cigarette?

    The total amount of nicotine in a cigarette varies, but most commercial cigarettes contain between 10 and 15 milligrams (mg) of nicotine. This is the amount present in the tobacco before the cigarette is lit, but this figure does not reflect the whole picture. Most of the nicotine in a cigarette is destroyed by combustion or remains in the sidestream smoke that you do not inhale. What really matters is the amount of nicotine that enters your bloodstream.

    ‘Light’ or ‘low-nicotine’ cigarettes:

    Don’t be fooled by these labels! Studies have shown that cigarettes marketed as ‘light’ or ‘low-nicotine’ contain about the same amount of nicotine as regular cigarettes. The real difference lies in their design (air holes around the filter), which can affect how you smoke.

    How much nicotine do you actually inhale?

    You do not inhale all of the 10 to 15 mg of nicotine contained in a cigarette. When you light a cigarette and take a puff, a significant amount of nicotine is destroyed by heat or escapes as sidestream smoke. The amount of nicotine that enters your lungs and is absorbed in your blood (bioavailability) depends on many factors, including how the cigarette is manufactured and, most importantly, how you smoke it. A person who smokes one cigarette absorbs approximately 1 to 2 mg of nicotine. Although this amount may seem small compared to the total 15 mg, it is enough to deliver a powerful dose to your brain and satisfy your addiction.

    The smoker’s behavior matters

    The way a person smokes is the most important variable in the actual dose received. Each person behaves differently, and two people smoking the same cigarette may absorb different amounts of nicotine. Your brain acts like a thermostat that determines how much nicotine you need to feel good and avoid nicotine withdrawal symptoms. As a result, people who smoke “low nicotine” or “light” cigarettes do so differently than normal cigarettes. This is called compensatory smoking:

    Deeper puffs: If you use a low-nicotine cigarette, your body compensates by taking deeper, longer puffs to get the amount of nicotine your brain needs.

    Smoking more often: You may also simply smoke more cigarettes throughout the day.

    Blocking the vents: Some ‘light’ cigarettes have ventilation holes near the filter. Smokers often cover these with their fingers or lips, either unconsciously or intentionally, which increases the concentration of smoke inhaled and, consequently, the dose of nicotine.

    This means that a heavy smoker can easily absorb 25 mg of nicotine per day by smoking a pack of 20 cigarettes, whether these are regular, low-nicotine or light cigarettes.

    Why it is important to understand nicotine levels and the speed of delivery:

    Nicotine is the main addictive chemical in tobacco, it is what drives you to smoke one cigarette after another. When you inhale smoke, nicotine quickly enters your bloodstream and reaches your brain. This rush causes the release of a chemical that makes you feel good (dopamine), which is why smoking can be enjoyable or soothing. But this feeling is temporary, as the nicotine level in your blood drops quickly, leading to withdrawal symptoms.

    When you smoke, nicotine reaches your brain within 10 to 20 seconds of inhalation. This rapid effect is one of the reasons why cigarettes are so addictive. Your brain learns to anticipate this rapid rush, and cravings develop when nicotine levels drop. Nicotine replacement therapies (patches, gum, tablets) release nicotine at a much slower rate and therefore do not create addiction, even though the molecule is the same.

    Understanding how nicotine works helps to understand why nicotine replacement therapies (such as patches, gum or lozenges) are designed in this way: to provide controlled, lower doses of nicotine at a slower rate of delivery and without the toxic chemicals found in cigarette smoke.

    Knowing all this can make it easier to quit smoking.

    Knowing these figures can help you understand how cigarettes are designed to make you addicted. The tobacco industry adjusts the chemical composition so that nicotine reaches your brain quickly and reliably, not only by controlling the amount of nicotine in cigarettes with the same precision used by drug manufacturers to produce prescription drugs, but also by using chemical additives.

    To quit smoking without experiencing nicotine withdrawal symptoms, you need to replace the “dirty” nicotine you currently get from smoking with “clean” nicotine from nicotine replacement therapy (NRT): products such as patches, gum and lozenges deliver a controlled and steady dose of nicotine without the thousands of other toxic chemicals found in cigarette smoke. Nicotine-based medicines release nicotine at a much slower rate than cigarettes, which is why these products are not addictive. They help you manage withdrawal symptoms when you quit smoking.

    Behavioural support from a healthcare professional increases the effectiveness of nicotine replacement therapy. Peer support groups and quit-smoking helplines can also help you manage the psychological and behavioral aspects of quitting smoking.

    If you do not want to use NRT, you can also get nicotine from e-cigarettes or nicotine pouches, these products deliver sufficient amounts of nicotine but no smoke, and are therefore much less dangerous than cigarettes.

  • Questionnaire : how much nicotine do you need?

    Questionnaire : how much nicotine do you need?

    Answer 5 questions to assess your nicotine consumption as a smoker (or your consumption when you smoked). We will then use this information to calculate the optimal nicotine concentration in your e-liquids, nicotine-based medications (patches, gum, tablets, inhalers), or nicotine pouches. Our statistics show that these 5 questions allow us to estimate your nicotine needs with twice the accuracy of using only the number of cigarettes smoked per day.

    Questionnaire:

    1- How many cigarettes do (did) you usually smoke per day?

    • 1-5 cig./day = 1 point
    • 6-10 cig./day = 2 points
    • 11-15 cig./day= 3 points
    • 16-20 cig./day= 4 points
    • 21+ cig./day = 5 points

    2- Usually, how long after waking up do (did) you smoke your first cigarette of the day?

    • 0-5 minutes = 5 points
    • 6-15 minutes = 4 points
    • 16-30 minutes = 3 points
    • 31-60 minutes = 2 points
    • Over 1 hour = 1 point

    3- On a scale of 0 to 100, indicate how heavily you smoke(d):

    • 0 = 0 point
    • 1-20 = 1 point
    • 21-40 = 2 points
    • 41-60 = 3 points
    • 61-80 = 4 points
    • 81-100 = 5 points

    4- On a scale of 0 to 10, how much smoke do you inhale each day (or inhaled when you smoked)? This amount depends on the number of cigarettes you smoke, how deeply you inhale, and the number of puffs.
    0: I do not inhale any smoke.
    10: I smoke so much that even if I tried, I could
    not inhale any more smoke.

    • 0 = 0 point
    • 1-2 = 1 point
    • 3-4 = 2 points
    • 5-6 = 3 points
    • 7-8 = 4 points
    • 9-10 = 5 points

    5- Indicate the number of milligrams of nicotine listed on your cigarette packet:

    • 0.1-0.5 mg = 1 point
    • 0.6-0.7 mg = 2 points
    • 0.8 mg = 3 points
    • 0.9 mg = 4 points
    • 1.0 mg or more = 5 points

    Now, add up and calculate your total number of points (maximum = 25 points)

    Data from our studies indicate that if your total is:

    • 0-4 points, you absorb between 0 and 7 mg of nicotine per day (mean =3.4 mg / day)
    • 5-9 points, you absorb between 7 and 14 mg of nicotine per day (mean = 10 mg / day)
    • 10-14 points, you absorb between 14 and 21 mg of nicotine per day (mean = 17 mg / day)
    • 15-19 points, you absorb between 21 and 28 mg of nicotine per day (mean = 24 mg / day)
    • 20-25 points, you absorb over 30 mg of nicotine per day.

    After quitting smoking, you must continue to absorb the same amount of nicotine in order to avoid withdrawal symptoms and to prevent yourself from starting smoking again because you cannot tolerate these symptoms.

    Consume enough nicotine from e-cigarettes, nicotine-based medications, or nicotine pouches for at least 3 months after quitting smoking.

    Dosage for nicotine medications

    Nicotine replacement medications release approximately 70% of the nicotine they contain. For example, a patch containing 21 mg of nicotine releases approximately 15 mg of nicotine.

    Use this factor (x 0.7) to calculate the optimal dose of your nicotine medication. For example, if you scored 12 points on our questionnaire, you need 17 mg of nicotine per day, and a 21 mg patch plus two 2 mg gums should provide you with the necessary dose.

    Dosage for nicotine pouches

    Use the same rule (x 0.7) as for nicotine medications.

    Dosage for e-cigarettes

    For e-cigarettes, the amount of nicotine aborbed by the user depends on many factors, in addition to the nicotine concentration in the e-liquid:

    • the other characteristics of the e-liquid (flavor, nicotine salt or freebase nicotine),
    • the characteristics of the device (battery, coil, wick)
    • your own level of nicotine addiction, your personal way on inhaling (number and depth of puffs), your social environment (whereas you are around smokers and vapers).

    Nevertheless, our previous studies conducted among former smokers who successfully quit smoking using e-cigarettes, and who responded to the above questionnaire offer some insights (1, 2, 3, 4).

    Vapers who were ex-smokers and obtained :

    • 0-4 points used e-liquids containing 10 mg / mL
    • 5-9 points used e-liquids containing 10-12 mg / mL
    • 10-14 points used e-liquids containing 12 mg / mL
    • 15-19 points used e-liquids containing 16 mg / mL
    • 20-25 points used e-liquids containing 18 mg / mL

    Use these results as a guide to choose your e-liquid, and do not underdose your e-liquids, because if you do, you risk unnecessarily:

    • using too much liquid,
    • exposing your lungs to too much vapour,
    • spending too much money on e-liquids,
    • experiencing nicotine withdrawal symptoms and running the risk of relapsing into smoking.

    There is no risk of nicotine overdose in regular smokers, as they can tell when they are consuming too much nicotine (specific taste in the mouth, sensation similar to that felt when you have smoked too much).

    4 important points to remember

    • To successfully quit smoking and avoid nicotine withdrawal symptoms, you need a sufficient amount of nicotine. Do not underdose your nicotine products.
    • You need a sufficient concentration of nicotine in your e-liquids (at least 10 mg/mL). Do not listen to retailers who insist that you buy 3 mg/mL liquids, they do this because they want to sell you more liquid.
    • Purchase your electronic cigarettes and e-liquids from a specialist shop rather than a kiosk or online, as the sales staff in these shops can advise you and allow you to try and taste different products until you find the one that best suits your needs.
    • The advice provided here does not replace that of a doctor or psychologist specialising in the treatment of nicotine addiction.

  • Nicotine strength for e-cigs

    Nicotine strength for e-cigs

    It is essential to choose the right nicotine concentration for your e-liquid: here is a brief explanation of how to do this. We have also developed a brief questionnaire to help you choose the nicotine concentration you need.

    What nicotine strength for my e-cigarette?

    If the nicotine level in your e-liquid is too low, you may not get enough nicotine, you may experience nicotine withdrawal symptoms and you may start smoking again. In addition, you will expose your lungs to excessive amounts of vapour, as you will vape more to achieve a satisfactory level of nicotine in your blood and brain. You will also need to buy more e-liquid to get the amount of nicotine your brain needs.

    With too high a nicotine level, you will experience throat irritation that will prevent you from inhaling, but there is no risk of overdose, as you will automatically stop inhaling when you have obtained the necessary dose of nicotine or when you feel signs of excessive dosing.

    The amount of nicotine you get from an e-cigarette:

    There is no simple calculation to convert the number of cigarettes you smoked per day into mg/mL (milligrams of nicotine per millilitre of e-liquid), because the amount of nicotine you get from your e-cigarette depends on the interaction of 3 factors, the liquid, the hardware and yourself :

    The liquid:

    • its nicotine concentration,
    • the chemical form of nicotine (salt or freebase),
    • the flavor (people tend to vape more if they like the flavor),
    • the amount of liquid you use per day,

    The hardware:

    • the battery, its tension measured in Volt (V), its duration,
    • the coil, its composition, its resistance (R) measured in Ohm,
    • the power of the device measured in Watt (W)
    • the wick.

    Yourself:

    • your level of nicotine addiction, as your brain acts as a thermostat and regulates the amount of nicotine you need,
    • your behavior: the number, frequency and volume of puffs, the depth of inhalation, how long you hold your breath between inhalation and exhalation,
    • your social interactions (people tend to vape more if they are around other smokers and vapers than if they are around people who disapprove of their vaping).

    A questionnaire to calculate the amount of nicotine you need:

    You can use our short questionnaire to help you calculate the optimal nicotine concentration for your e-liquid, this concentration will be determined by the number of point you obtain. Vapers who successfully quit smoking and answered our questionnaire and obtained :

    • 0-4 points used e-liquids containing 10 mg / mL
    • 5-9 points used e-liquids containing 10-12 mg / mL
    • 10-14 points used e-liquids containing 12 mg / mL
    • 15-19 points used e-liquids containing 16 mg / mL
    • 20-25 points used e-liquids containing 18 mg / mL

    The amount of nicotine you get from smoking a cigarette:

    The amount of nicotine you absorb when smoking a cigarette depends largely on your own behaviour, not just on the characteristics of the cigarette itself. Each manufactured cigarette contains between 6 and 17 milligrams (mg) of nicotine, but smokers only inhale between 1 and 2 mg of nicotine per cigarette. The number of nicotine mg indicated on cigarette packets is not useful, as it is obtained from machines that do not perfectly replicate your own behaviour. As a result, these figures often underestimate the amount you absorb when smoking a cigarette.

    Furthermore, the relationship between the number of cigarettes smoked per day and the concentration of nicotine in the blood is not linear (it does not increase significantly beyond 20 cigarettes per day).Therefore, you cannot use your number of cigarettes per day and the nicotine concentration indicated on your cigarette pack to calculate or deduce the amount of nicotine you absorb each day with your e-cigarette.
