Nicotine and caffeine – what is actually the difference?<\/strong><\/h1>\n\n\n\n

Nicotine and caffeine are two of the most widely used stimulants in the world, but they act on the body in entirely different ways. Nicotine activates nicotinic receptors in the brain and triggers a rapid release of dopamine, while caffeine blocks adenosine receptors, the signals that would otherwise make us feel tired. In this article, we go through how the two substances work individually, what research says about what happens when they are combined, and why their dependency mechanisms differ.<\/p>\n\n\n\n

Key points<\/strong><\/h2>\n\n\n\n

Nicotine and caffeine affect the brain via different receptors, but both increase the sense of alertness and stimulate the dopamine system.<\/strong><\/p>\n\n\n\n

Nicotine affects the enzyme CYP1A2 in the liver, causing the body to break down caffeine up to 50% faster in nicotine users.<\/strong><\/p>\n\n\n\n

Nicotine has a half-life of 1-2 hours; caffeine’s is approximately 5 hours, which explains why the effects last for different lengths of time.<\/strong><\/p>\n\n\n\n

Research shows that the two substances can enhance each other’s appetite-suppressing and stimulating effects when used simultaneously.<\/strong><\/p>\n\n\n\n

    Where do nicotine and caffeine come from?<\/strong><\/h2>\n\n\n\n

    Despite often being mentioned in the same breath, nicotine and caffeine have very different origins. Both are produced naturally by plants, but for the same reason: as a chemical defence against insects and pests.<\/p>\n\n\n\n

    Caffeine occurs naturally in over 60 plant species, including coffee beans, tea leaves, and cocoa beans. It was first isolated chemically in 1819 by the German chemist Friedlieb Ferdinand Runge, following a tip from none other than Goethe. Coffee spread from Ethiopia and Yemen via the Middle East to Europe in the 17th century, and it is said that it was thanks to Pope Clement VIII, who gave the drink his blessing, that it gained traction on the continent. Tea and coffee are today among the world’s most consumed beverages, making caffeine the most widely used psychoactive substance in the world.<\/p>\n\n\n\n

    Nicotine is best known from the tobacco plant, but is actually found in small amounts in several common vegetables such as tomatoes, potatoes, aubergine, and cauliflower. The amounts are so low, however, that they have no noticeable effect. Tobacco was used by indigenous peoples in South America in both rituals and medicine long before it was introduced to Europe in the 15th century. Today, nicotine is used in everything from traditional tobacco snus and white \u0623\u0643\u064a\u0627\u0633 \u0627\u0644\u0646\u064a\u0643\u0648\u062a\u064a\u0646<\/a> to nicotine patches and cessation products. There is also synthetic nicotine, manufactured in laboratories without any involvement of the tobacco plant.<\/p>\n\n\n\n

    How nicotine and caffeine affect the body<\/strong><\/h2>\n\n\n\n


    Although both substances are classified as stimulants and affect the brain’s dopamine system, they do so via entirely different mechanisms and with different time profiles.<\/p>\n\n\n\n

    \u0643\u0627\u0641\u064a\u064a\u0646<\/strong><\/h3>\n\n\n\n

    Caffeine works primarily by blocking adenosine receptors in the brain. Adenosine is a substance that builds up naturally throughout the day and normally signals to the brain that it is time to rest. When caffeine blocks these receptors, the fatigue signal is suppressed, making us feel more alert and awake. At the same time, dopamine activity in the brain’s reward system increases, which can contribute to improved mood and greater motivation. The effect is usually noticeable within 15-45 minutes of intake, and caffeine’s half-life is approximately 5 hours, meaning a cup of coffee in the afternoon can still have an effect late in the evening.<\/p>\n\n\n\n

    \u0627\u0644\u0646\u064a\u0643\u0648\u062a\u064a\u0646<\/strong><\/h3>\n\n\n\n

    Nicotine binds to nicotinic receptors (a type of acetylcholine receptor) in the brain and central nervous system. It triggers a rapid release of dopamine and other neurotransmitters such as noradrenaline, producing a sense of wellbeing, sharpness, and increased alertness. The effect sets in considerably faster than caffeine: when using snus, it is noticeable within 1-2 minutes. Nicotine’s half-life, however, is only 1-2 hours, meaning the effect fades relatively quickly compared to caffeine.<\/p>\n\n\n\n

    When combined<\/strong><\/h3>\n\n\n\n

    Here lies one of the most interesting and frequently overlooked findings in the research. Nicotine affects the enzyme CYP1A2 in the liver, which is the primary enzyme responsible for breaking down caffeine. In nicotine users, caffeine is broken down considerably faster. A study published on PubMed found that the half-life of caffeine in smokers was on average 3.5 hours, compared to 6 hours in non-smokers. Another study showed that four days of nicotine abstinence led to a 46% increase in caffeine levels in the blood. In practical terms, this means nicotine users may need more coffee to feel the same effect, and those who quit nicotine may notice that caffeine suddenly feels considerably stronger.<\/p>\n\n\n\n

    A controlled study published in the journal Diabetes, Obesity and Metabolism also found that caffeine enhances nicotine’s appetite-suppressing effect. The combination of the two substances produced a greater reduction in hunger than either substance alone.

    Is nicotine more addictive than caffeine?<\/strong><\/h2>\n\n\n\n

    Dependency is not simply a matter of how often something is used, but of how a substance affects the brain and behaviour over time. In healthcare, different types of dependency are classified using ICD codes. Nicotine dependency carries the code F17.2, while caffeine dependency falls under F15.2. The fact that both appear in the same diagnostic system underlines that both can create a clinically relevant dependency, albeit of different severity.<\/p>\n\n\n\n

    \u0627\u0644\u0625\u062f\u0645\u0627\u0646 \u0639\u0644\u0649 \u0627\u0644\u0646\u064a\u0643\u0648\u062a\u064a\u0646<\/strong><\/h3>\n\n\n\n

    Nicotine affects the brain’s reward system in a way that can lead to both physical and psychological dependency. With regular use, the brain adapts to nicotine’s presence and the number of nicotine receptors increases, which can affect many functions in the body. The absence of the substance can cause withdrawal symptoms such as irritability, difficulty concentrating, and sleep problems. According to the report Nicotine and the Brain from EPHI, nicotine dependency is characterised by loss of control, difficulty quitting, and discomfort during abstinence. Professor Fredrik Nystr\u00f6m, senior physician and professor of internal medicine at Link\u00f6ping University, notes that there is well-conducted research showing that caffeine and nicotine together enhance each other’s effect on the body’s energy expenditure.<\/p>\n\n\n\n

    Caffeine dependency<\/strong><\/h3>\n\n\n\n

    Caffeine can also create habits, and at high intake, an abrupt break can cause headaches, fatigue, and irritability for a few days. These symptoms are generally milder and shorter-lived than those associated with nicotine withdrawal. An important practical consequence: someone who stops using nicotine may suddenly find that caffeine’s effects feel noticeably stronger, as the body no longer breaks down caffeine as quickly. This is worth bearing in mind if, for example, you continue drinking the same amount of coffee as before.<\/p>\n\n\n\n

    Summary<\/strong><\/h3>\n\n\n\n

    Both substances can create habits, but the dependency mechanisms differ in strength and nature. Nicotine has a stronger association with classic dependency patterns, while caffeine’s effects during withdrawal are, in most cases, temporary and manageable.<\/p>\n\n\n\n

    Frequently asked questions<\/strong><\/h2>\n\n\n\n

    Is there snus with caffeine?<\/strong><\/h3>\n\n\n\n

    Yes, \u0643\u0627\u0641\u064a\u064a\u0646 <\/a>pouches exists and contains caffeine but no nicotine. It is used in the same way as white snus and is absorbed through the oral mucosa, which can produce a slightly faster effect compared to drinking coffee, where caffeine passes through the digestive system. Most caffeine portions contain 50-100 mg of caffeine per portion, roughly equivalent to a cup of coffee.<\/p>\n\n\n\n

    What happens to caffeine sensitivity when you quit snus?<\/strong><\/h3>\n\n\n\n

    This is a common but little-known effect: when you quit nicotine, you may notice that coffee feels stronger than usual. This is because nicotine stimulates the enzyme CYP1A2 in the liver, which breaks down caffeine. Without nicotine, the activity of that enzyme decreases, and caffeine stays in the bloodstream for longer. Research shows that caffeine levels can increase by up to 46% after just four days of nicotine abstinence.<\/p>\n\n\n\n

    Can you get nicotine from ordinary food?<\/strong><\/h3>\n\n\n\n

    Yes, nicotine occurs naturally in vegetables such as tomatoes, potatoes, aubergine, and cauliflower, but in such small amounts that they have no noticeable effect on the body.<\/p>\n\n\n\n

    What happens in the body when you combine nicotine and caffeine?<\/strong><\/h3>\n\n\n\n

    Both substances stimulate the dopamine system via different pathways. Research shows that the combination can enhance the appetite-suppressing effect and produce a stronger sense of alertness than either substance alone. At the same time, nicotine affects how quickly the body breaks down caffeine, meaning nicotine users generally need more coffee to feel the same effect as non-users.<\/p>\n\n\n\n

    Which substance is more addictive?<\/strong><\/h3>\n\n\n\n

    Nicotine is generally considered more addictive than caffeine. Withdrawal symptoms during nicotine abstinence are typically more pronounced and longer-lasting. Both have their own ICD codes in the medical diagnostic system, but nicotine dependency (F17.2) is considered clinically more significant than caffeine dependency (F15.2).<\/p>\n\n\n\n

    Summary<\/strong><\/h2>\n\n\n\n

    Nicotine and caffeine are both stimulating substances that affect the brain and can increase the sense of alertness, but they do so in different ways and with different dependency potential. Caffeine works by blocking fatigue signals and has a half-life of approximately 5 hours, while nicotine directly activates the brain’s reward system and acts faster but for a shorter duration. One of the most practically relevant findings is that nicotine affects how quickly the body metabolises caffeine: nicotine users break down caffeine up to 50% faster, which explains why many snus and cigarette users drink more coffee. Those who quit nicotine should be aware that caffeine’s effects may feel noticeably stronger during the first few weeks. Would you like to try a nicotine-free alternative with a similar feel?
