Nicotine is highly addictive, but some scientists think we need to distinguish between the effects of nicotine and the effects of cigarettes. Smoking is certainly a killer, but how does nicotine affect the body and why are some researchers interested in it? Read on to find out.<\/p>\n
Disclaimer<\/i><\/b>: As a medication, nicotine replacement therapy can help people stop smoking. However, we are not recommending the general use of nicotine by writing this post. If you want to quit smoking, talk to your healthcare provider about the best options available for you. Stop-smoking programs should also include counseling and additional support. The aim of this post is to summarize some data from the scientific literature for purely informational purposes.<\/i><\/p>\n Nicotine is an addictive substance that naturally occurs as a liquid alkaloid in many plants of the nightshade family. Tomatoes, potatoes, eggplant, and tobacco all contain nicotine (R<\/a>).<\/p>\n Nicotine is what gets people addicted to cigarettes. <\/b>Scientists view it as the initial trigger, though it plays a minor role in causing smoking-induced diseases like cancer, heart disease, and lung disease. These diseases result from exposure to toxins in tobacco smoke (R<\/a>).<\/p>\n Tobacco and tobacco smoke contain a dangerous mixture of thousands of chemicals (R<\/a>, R<\/a>).<\/p>\n But simply put, people would probably never inhale cigarette smoke if it wasn\u2019t for nicotine. Nicotine is what gets people hooked – and it\u2019s what keeps them hooked (R<\/a>, R<\/a>).<\/p>\n According to a recent scientific review, cigarette smoking remains a leading cause of preventable disease and premature death in the United States and other countries.<\/b> Lifelong smokers have about a 50% chance of dying prematurely from a complication of smoking (R<\/a>).<\/p>\n According to the FDA, using any tobacco product that contains nicotine can lead to nicotine addiction <\/b>(R<\/a>).<\/p>\n The following products all contain nicotine:<\/p>\n Having these dangers in mind, we highly advise against smoking or using tobacco. If you are a smoker, seek professional help as soon as possible. Stopping smoking is among the most important things you can do to improve your health and longevity. <\/b><\/p>\n Additionally, no e-cigarette has yet been approved as a cessation device or a <\/b>modified risk tobacco product<\/i><\/b>, which are products that present lower health risks to people compared to existing products. More research is needed to understand the effects of e-cigarettes on addicted adult smokers [R<\/a>].<\/p>\n When used appropriately, nicotine replacement therapy can help people stop smoking<\/b>. It poses the lowest risk to health among all nicotine-containing products. Nicotine replacement therapy is available [R<\/a>]:<\/p>\n Consult your doctor or pharmacist for any questions about using these products for smoking cessation<\/p>\n People have the best chance of success when they are ready to commit to the decision to quit. Smoking cessation programs usually also include counseling, behavioral therapy, and support.<\/p>\n This section summarizes the existing experimental human, animals and cell-based research on nicotine and nicotine-related targets. The aim of the existing research is to guide further investigational efforts.<\/p>\n Scientists are interested in nicotine because it helps them understand the pathways of reward and addiction in the brain. They are also studying so-called nicotine receptors, to which many substances aside from nicotine can bind to.<\/p>\n Some researchers are examining the effects of special nicotine formulations on cognition. On the other hand, certain drug companies are interested in various nicotine-related compounds. These nicotine-like compounds are undergoing early trials for ADHD, schizophrenia, and as anti-smoking pills.<\/p>\n Despite ongoing research efforts, no nicotine-related drugs are on the market yet since their benefits and risks have not been established in large-scale trials.<\/p>\n Research on nicotine-related pathways and compounds is still in the early stages. The studies listed below should not be interpreted as supportive of any health effect.<\/p>\n Scientists suspect that other compounds in tobacco interact with nicotine and act as monoamine oxidase inhibitors (MAOI). In one rat study, this likely increased the animals\u2019 motivation to self-administer nicotine. The authors hypothesize that this mechanism may underlie the intense reinforcing properties of cigarette smoking that lead to addiction<\/b> [R<\/a>, R<\/a>].<\/p>\n Additionally, MAOIs prevent the breakdown of neurotransmitters like dopamine, serotonin, and norepinephrine in certain areas of the brain, increasing their levels.<\/p>\n Nicotine activates nicotinic acetylcholine receptors. Cells studies suggest that acutely, it mimics the effects of acetylcholine in the brain<\/a>. Chronically, however, it may have the opposite effects. Researchers believe that long-term nicotine may cause long-lasting changes in the nervous system by, in part, disabling<\/i> nicotinic cholinergic signaling [R<\/a>].<\/p>\n Nicotinic acetylcholine receptors are found in different brain regions, including the thalamus, occipital cortex, and cerebellum. Nicotine can act on various subsets of nicotinic receptors, including alpha-4, beta-2, and alpha-7, the exact effects of which are an area of research [R<\/a>, R<\/a>].<\/p>\n Some investigators suggest that nicotine can also indirectly increase dopamine in parts of the brain, which also likely causes reinforcing effects and dependance<\/b> [R<\/a>, R<\/a>].<\/p>\nWhat is Nicotine?<\/b><\/span><\/h2>\n
