Tobacco

Although many people smoke because they believe cigarettes calm their nerves, smoking releases epinephrine, a hormone which creates physiological stress in the smoker, rather than relaxation. The use of tobacco is addictive. Most users develop tolerance for nicotine and need greater amounts to produce a desired effect.

Smokers become physically and psychologically dependent and will suffer withdrawal symptoms including: changes in body temperature, heart rate, digestion, muscle tone, and appetite. Psychological symptoms include: irritability, anxiety, sleep disturbances, nervousness, headaches, fatigue, nausea, and cravings for tobacco that can last days, weeks, months, years, or an entire lifetime.

Risks associated with smoking cigarettes: Cigarette smoking is perhaps the most devastating preventable cause of disease and premature death.

Smoking is particularly dangerous for teens because their bodies are still developing and changing and the 4,000 chemicals (including 200 known poisons) in cigarette smoke can adversely affect this process.

Cigarettes are highly addictive. One-third of young people who are just "experimenting" end up being addicted by the time they are 20.
