What are the uses of nicotine?
Nicotine can temporarily make someone feel alert and better able to concentrate. It can also relieve stress and anxiety and improve mood. But these effects go away quickly, which is why people keep going back to cigarettes and other tobacco products and eventually get addicted. Nicotine has also showed promise as a treatment for depression, attention-deficit hyperactivity disorder, Tourette’s, and schizophrenia. Nicotine appears to be safe when used appropriately.Nicotine pouches Placed in the mouth between the lip and gum, nicotine is absorbed through the oral mucous membrane. Since nicotine pouches contain no tobacco, and require no combustion, their use avoids many of the risks associated with smoking that result from the burning of tobacco.For decades, the tobacco industry has promoted the myth that nicotine is as harmless as caffeine. Nonetheless, evidence shows that nicotine is far from innocuous, even on its own. In fact, numerous studies have demonstrated that nicotine can harm multiple organs, including the respiratory and cardiovascular systems.Nicotine pouches present several cardiovascular risks due to the nicotine content. The use of these products can lead to increased heart rate and blood pressure, which may increase the risk of developing cardiovascular diseases such as hypertension, heart disease, and potential heart attacks.Smokeless tobacco is widely used by athletes to enhance performance. Nicotine is a central nervous system stimulant and acts on cardiocirculatory and metabolic systems, involving tissue blood flow and circulatory vasoreactivity.
What is the need for nicotine?
Over time, your body and brain get used to having nicotine in them. About 80–90% of people who smoke regularly are addicted to nicotine. Nicotine reaches your brain within 10 seconds of when it enters your body. It causes the brain to release adrenaline, and that creates a buzz of pleasure and energy. Capitalizing on mechanisms that subserve natural rewards, nicotine activates midbrain dopamine neurons directly and indirectly, and nicotine causes dopamine release in very broad target areas throughout the brain, including the NAc, amygdala, and hippocampus.Preclinical models and human studies have demonstrated that nicotine has cognitive-enhancing effects, including improvement of fine motor functions, attention, working memory, and episodic memory.Nicotine is well known to have serious systemic side effects in addition to being highly addictive. It adversely affects the heart, reproductive system, lung, kidney etc.Smokers may rely on nicotine to destress. Nicotine is a mood-altering drug in tobacco that can have calming effects. However, smoking can increase long-term stress and anxiety. Nicotine is a stimulant drug that reaches the brain in 10 seconds.Many patients have reported improvements in symptoms such as fatigue and brain fog. Nicotine’s interaction with nicotinic acetylcholine receptors may play a role in reducing inflammation and restoring nervous system balance.
Is nicotine haram?
In the Hanafi school, nicotine is generally not considered haram by itself, but may become haram when it causes harm or addiction. The Hanafi approach emphasizes harm prevention, so if nicotine use leads to significant health issues, it may be ruled haram under those conditions. Nicotine’s cognitive effects have gained significant attention in recent decades, and some non-smokers have even started using nicotine gum or patches as a nootropic. Research has shown that nicotine can speed up reaction time, improve working memory, and enhance focus and attention.Finally, it has been suggested that the cognitive enhancing effects of nicotine may contribute to its mood-enhancing or mood-stabilizing effects [125]. For example, nicotine may alleviate the negative consequences of a stressor by improving attentional focus on a benign distractor stimulus [126].Evidence indicates that nicotine exerts immunosuppressive effects on the adaptive and innate immune responses of different immune cell types and therefore is immunomodulatory. It is unclear, however, if this may exacerbate risk for other diseases.Nicotine is a dangerous and highly addictive chemical. It can cause an increase in blood pressure, heart rate, flow of blood to the heart and a narrowing of the arteries (vessels that carry blood). Nicotine may also contribute to the hardening of the arterial walls, which in turn, may lead to a heart attack.
Does nicotine affect sperm?
In males, nicotine affects the testes where prolonged exposure changes the morphology of spermatogenic cells, reduces sperm production, decreased steroidogenesis and inhibits spermatogenesis resulting in decreased sperm counts, poor sperm motility and increased levels of DNA damage [20,21]. Tobacco smoking leads to reduced semen quality including semen volume, sperm density, motility, viability, and normal morphology. Furthermore, reproductive hormone system disorders, dysfunction of spermatogenesis, sperm maturation process, and impaired spermatozoa function have also been observed in smokers.In males, nicotine affects the testes where prolonged exposure changes the morphology of spermatogenic cells, reduces sperm production, decreased steroidogenesis and inhibits spermatogenesis resulting in decreased sperm counts, poor sperm motility and increased levels of DNA damage [20,21].Tobacco smoking leads to reduced semen quality including semen volume, sperm density, motility, viability, and normal morphology.

Does nicotine improve memory?
Nicotine can activate PDE-5, TRβ and CaMKII, and activation of these proteins can lead to increased neuronal communication that ultimately improves memory function. In addition, nicotine activates the pro-survival PI3K/AKT pathway that increases LTP and improves memory dysfunction caused by AD. Nicotine improves cognitive functioning in smokers and psychiatric populations, but its cognitive-enhancing effects in healthy nonsmokers are less well understood. Nicotine appears to enhance certain forms of cognition in nonsmokers, but its specificity to subtypes of cognition is not known.In small clinical trials, the dose of nicotine that improved some aspects of cognition ranged from 5 to 15 mg/day [3; 4; 20]. Higher doses likely have greater risk of sleep side effects [21].For example, nicotine influences a wide variety of cognitive functions such as attention, learning and memory (Yuan et al. Alzheimer’s disease (AD), Parkinson’s disease (PD), age-associated memory impairment, .Nicotine rebalances NAD+ homeostasis and improves aging-related symptoms in male mice by enhancing NAMPT activity. Nat Commun. Feb 17;14(1):900.
Is nicotine good for non-smokers?
They come to the conclusion that even without the influence of tobacco, nicotine is extremely bad for you. There is an increased risk of cardiovascular, respiratory, gastrointestinal disorders. There is decreased immune response and it also poses ill impacts on the reproductive health. If you smoke occasionally, you may not identify as a smoker or believe it’s as bad as smoking regularly, but even an occasional cigarette puts you at risk for serious health problems, including cancer, chronic obstructive pulmonary disease, emphysema, heart disease and stroke.Tobacco toxicology and teratogenic effects Smoking directly exposes the epithelial tissue to at least 60 powerful chemical carcinogens with the potential to cause DNA damage to larynx, bronchi, and lung epithelial cells.More people die from lung cancer than any other type of cancer. Cigarette smoking is the number one risk factor for lung cancer; it’s responsible for close to 90% of lung cancer cases.
