Nicotine is a highly addictive substance found in tobacco products and e-liquids for electronic cigarettes. It can be naturally extracted from tobacco plants or synthesized in labs, and is also used as a pesticide. Tobacco products, including cigarettes, cigars, heated tobacco, and most e-cigarettes, contain nicotine. This article covers the history and impact of nicotine, its health effects, and treatment options for nicotine dependence
Nicotine comes from tobacco plants, part of the nightshade family, originally from South America. Indigenous people used tobacco for chewing, smoking, and religious ceremonies. European colonizers later exported tobacco for profit, popularizing its recreational use. The tobacco industry has a long history of targeting specific communities based on race, regional demographics, and cultural factors to promote tobacco use
Tobacco companies heavily marketed menthol products to Black and low-income communities, making cigarettes more appealing. The CDC reports that non-Hispanic Black or African American people are more likely to smoke menthol cigarettes. Menthol can increase nicotine’s addictiveness, leading to prolonged tobacco use and a higher risk of tobacco-related diseases
THE IMPACT OF NICOTINE
Nicotine causes temporary happiness and relaxation, increasing heart rate and oxygen use. It quickly reaches the brain, causing a brief surge in endorphins and dopamine, which creates pleasure and reinforces smoking. Frequent use changes brain function, leading to addiction and withdrawal symptoms when quitting
Impact on Cognitive Function
Nicotine can temporarily boost attention and memory, but long-term use can impair cognitive ability and increase Alzheimer’s risk. The short-term benefits do not outweigh these long-term risks. Quitting nicotine can cause withdrawal symptoms affecting attention and memory, as well as sleep disturbances
Side Effects of Nicotine
Certain nicotine products may also have specific side effects. According to a credible source from the American Cancer Society, side effects of nicotine patches include:
- Skin irritation
- Accelerated heart rate
- Dizziness
- Sleep problems
- Headaches
- Nausea
- Muscle soreness or stiffness
SMOKING
Nicotine, found in tobacco products, is addictive and changes brain function. According to the NIDA, most smokers are frequent smokers due to nicotine addiction. Smoking is the leading preventable cause of death, damaging nearly every organ and increasing the risk of heart disease, stroke, and lung cancer. Although nicotine itself isn’t carcinogenic, tobacco smoke contains at least 69 cancer-causing chemicals
ARE ELECTRONIC CIGARETTES AND VAPORIZERS SAFE?
ENDS, such as e-cigarettes, heat liquid to produce vapor containing nicotine, solvents, and flavors. Not safe for pregnant women, nicotine can harm fetal development. FDA warns against THC-containing vaping products and those of unknown origin due to severe lung damage reports. Many unknowns remain about e-cigarettes, including their chemicals and health impacts, suggesting other quitting methods might be better
NICOTINE DEPENDENCE TREATMENT
According to NIDA, a 2020 survey found that about 23.6 million people aged 12 and over had nicotine dependence in the past 30 days. Treatment for nicotine dependence may include:
Nicotine Replacement Therapy
Nicotine Replacement Therapy (NRT) supplies small doses of nicotine that bind to nicotine receptors, reducing cravings. It includes patches, sprays, lozenges, or gum and is FDA-approved as the least harmful nicotine option
Medications
Certain medications can aid in nicotine dependence treatment. Bupropion affects brain chemicals and is as effective as NRT for quitting smoking. Varenicline stimulates nicotine receptors but to a lesser extent than nicotine, and is more effective than bupropion for smoking cessation
Counseling and Psychological Support
Combining NRT or smoking cessation medications with behavioral therapy improves smoking cessation success. Options include speaking with mental health professionals, using psychotherapy like CBT, mindfulness techniques, helplines, automated messaging, and self-help materials
CONCLUSION
Nicotine, highly addictive in tobacco products, often drives smoking. Side effects include dizziness, increased heart rate, and headache. Nicotine is toxic and can cause poisoning, requiring immediate medical attention if suspected. It can increase tobacco product use, leading to serious health issues. Quitting options include medication, nicotine replacement therapy, and behavioral therapy
