1. Nicotine is highly addictive and causes physical and psychological dependence. Withdrawal from nicotine can cause cravings and symptoms like headaches and irritability.
2. Smoking harms nearly every organ in the body and causes many types of cancer as well as respiratory and heart diseases. Secondhand smoke also increases health risks.
3. Tobacco use, especially before age 18, often leads to long-term addiction. Social influences and misinformation can convince youth to experiment with tobacco despite known health risks. Resisting peer pressure requires assertiveness, education, and choosing non-smoking friends.
