Drugs are considered one of the most dangerous dangers that threaten modern societies because they have destructive effects on human physical and mental health, family stability, and social security. Drug abuse does not harm the addict alone, but also affects others around him and the society as a whole. First: Health damages Drugs lead to the deterioration of vital body functions, especially the nervous system, weakening concentration and causing memory disorders. They also damage the liver, heart, and lungs, weaken the immune system, and in many cases lead to death due to overdose. Second: Psychological and mental damages Drug users suffer from anxiety, depression, and aggression, and may even experience hallucinations and loss of reality. They lose control over their behavior and may commit dangerous acts. Third: Social and family damages Drug abuse negatively affects the family. The addict loses the ability to take responsibility, family conflicts increase, and this may lead to family breakdown and the loss of children. Fourth: Economic and security damages Drug abuse leads to a decrease in productivity at work, spread of unemployment and poverty, and an increase in crime rates such as theft, fraud, and assault due to the need for money. Fifth: Prevention and treatment Prevention begins with health awareness in school and family, encouraging youth to engage in useful activities. Treatment requires cooperation between doctors, psychologists, and social specialists to rehabilitate the addict and reintegrate them into society. Conclusion Combating drugs is a shared responsibility between the family, school, society, and the state. With awareness and support, we can protect young people and build a generation able to resist this dangerous scourge. Almustaqbal University, The First University in Iraq
