Ending Tobacco Use

Components of Tobacco Products

Tobacco contains numerous chemicals that contribute to addiction and have damaging effects on overall health. These chemicals are delivered through cigarettes, cigars, pipes, snuff, or chewing tobacco.

• Nicotine: A highly addictive compound that stimulates dopamine release, leading to pleasure and dependence.

• Carbon Monoxide (CO): A poisonous gas that reduces oxygen delivery in the body, increasing cardiovascular risk.

• Formaldehyde: A carcinogen used in embalming fluids; exposure increases cancer risk.

• Polycyclic Aromatic Hydrocarbons (PAHs): A group of carcinogenic compounds formed during tobacco combustion.

• Tobacco-Specific Nitrosamines (TSNAs): Potent carcinogens unique to tobacco products.

• Inorganic Toxins: Includes metals like nickel, which can cause respiratory issues and allergic reactions.

Nicotine Addiction

Nicotine is the major addictive component in tobacco, making users physically dependent on smoking.

• Triggers the release of dopamine, leading to feelings of happiness, satisfaction, and pleasure.

• Nicotine withdrawal can cause restlessness, irritability, and cravings, typically peaking 2-4 weeks after quitting.

• Nicotine replacement products (e.g., e-cigarettes) deliver nicotine more rapidly than regular cigarettes.

Example: Nicotine decreases appetite, which may be associated with weight loss among smokers.

Trends in Smoking

Although approximately 1 in 5 U.S. adults engage in smoking, the overall rate has been decreasing since 2005. Men tend to smoke at higher rates than women, and smoking-related deaths account for nearly 1 out of every 5 adult deaths.

• Higher education is associated with lower rates of smoking.

• Traditional smoking includes cigarettes and similar products.

Trends in College Students

The trend in smoking among college students has been decreasing over the past 20 years, reflecting broader public health efforts and changing social norms.

• Increased awareness and education have contributed to the decline.

• Legislation, such as raising the legal age for tobacco purchase, has also played a role.

Health Effects of Tobacco Use

Tobacco use is associated with numerous health risks, including:

• Cancer: Due to carcinogens like PAHs, TSNAs, and formaldehyde.

• Cardiovascular Disease: Carbon monoxide and nicotine increase heart disease risk.

• Respiratory Issues: Inorganic toxins and irritants cause lung damage and allergies.

• Metabolic Effects: Nicotine can decrease appetite and increase metabolic rate.

Secondhand Smoke and Nicotine Exposure

Exposure to secondhand smoke and nicotine can have immediate and long-term health effects:

• Short-term exposure can decrease appetite and increase blood pressure.

• Long-term exposure increases risk for heart disease and cancer.

Factors Influencing Decline in Smoking

• Changes in social norms and acceptance.

• Public health campaigns and education.

• Legislation raising the legal age for tobacco purchase.
