Tobacco is a shrub whose leaves were dried & fermented before it can be used to make tobacco products. Tobacco includes nicotine, a substance that can cause addiction, yet many people struggle to quit smoking. Many other potentially dangerous compounds can be present in tobacco or are formed when burned.
Tobacco can be smoked, chewed, or sniffed. Cigarettes, cigars, bidis, and kreteks are examples of smoked tobacco products. Some individuals also use a pipe or hookah to smoke loose tobacco (water pipe). Chewing nicotine, snuff, dip, and snus are chewed tobacco products; snuff can also be smelled.
What are the effects of tobacco on the brain?
When a person consumes a tobacco product, the nicotine is quickly absorbed. Nicotine stimulates the adrenal to release the hormone epinephrine as soon as it enters the bloodstream (adrenaline). Epinephrine is a neurotransmitter that activates the central nervous system, raising blood pressure, respiration, and heart rate. Nicotine affects the brain’s reward circuits and boosts levels of the neurotransmitter dopamine, which promotes rewarding behaviors, similar to cocaine and heroin. According to studies, other compounds in cigarette smoke, including acetaldehyde, can boost the brain’s nicotine effects.
Is it possible to overdose on nicotine?
Nicotine is deadly, and while overdosing is rare, it is conceivable. When a person takes too much of a medicine, a toxic reaction ensues, resulting in significant, life-threatening symptoms or death. Nicotine poisoning is most common in children who swallow e-cigarette juice or chew nicotine gum/patches intended to quit smoking. Breathing difficulties, vomiting, fainting, headaches, weakness, and an elevated or lowered heart rate are some of the symptoms. Anyone concerned that a kid or adult is suffering from a nicotine addiction should seek medical attention.
Cigarettes that are powered by electricity
Electronic cigarettes, e-cigarettes, and e-vaporizers are battery-powered devices that deliver nicotine, flavorings, and other substances to the lungs in a vapor rather than smoke. They can be bought, and one can shop smoking accessories online also. Because e-cigarettes do not burn tobacco, they are frequently advertised as safer than regular cigarettes. However, experts know too little about the medical problems associated with using these devices. Non-nicotine drugs such as bupropion (Zyban®) & varenicline (Chantix®) are FDA-approved and have assisted people in quitting smoking. They work by targeting nicotine brain receptors, reducing withdrawal symptoms, and preventing nicotine’s effects if patients reintroduce smoking.
Chewing gum, transdermal patches, sprays, inhalers, & lozenges are among the FDA-approved NRT products now on the market. While attempting to quit smoking, NRTs offer a controlled nicotine dosage to alleviate withdrawal symptoms.
