The document discusses the harms of smoking, drinking alcohol, and taking illegal drugs. Smoking cigarettes exposes the body to nicotine, tar, and carbon monoxide, which are addictive and cause issues like cancer, heart disease, and lung damage. Drinking alcohol in excess amounts, known as binge drinking, can negatively impact health, behavior, and relationships. While some legal drugs have benefits if taken properly, illegal drugs and misuse of alcohol and cigarettes ultimately harm the body. The document emphasizes educating people about these risks and implementing policies like higher prices and restrictions to reduce substance abuse.
