  • Chemical Composition: Cigarette smoke contains over 4,000 chemicals, including at least 43 known carcinogens that can cause cancer.

  • Nicotine: A poisonous stimulant found in tobacco that increases Central Nervous System (CNS) activity, impacting vital body functions.

Types of Smoke

  1. Mainstream Smoke: Inhaled by the smoker directly.

  2. Sidestream Smoke: Released from the lit end of a cigarette, found to be more harmful than mainstream smoke.

  3. Third-hand Smoke: Residual smoke that settles on surfaces, remaining harmful long after smoking occurs.

Environmental Impact and Regulations

Effects of Alcohol Consumption

  • Alcohol affects the CNS, which controls mental processes, including memory, speech, and decision-making skills.

  • Blood-Alcohol Concentration (BAC): Measured in percentages; a BAC of 0.3 - 0.5% can lead to coma, brain damage, or death.

Alcoholism

  • Characterized by compulsive and uncontrollable drinking, leading to an inability to function normally without alcohol.
