School-based prevention programmes play a crucial role in preventing drug abuse among children and adolescents. Schools are one of the most important social institutions where young people spend a large part of their time. Because students are in a formative stage of physical, psychological, and social development, they are particularly vulnerable to experimenting with drugs and other harmful substances. School environments provide a structured setting where knowledge, attitudes, and behaviors related to drug use can be shaped positively. Effective school-based prevention programmes aim to educate students, build life skills, strengthen resilience, and create supportive environments that discourage drug use. One of the most important components of school-based prevention programmes is drug education. Drug education programmes provide accurate and age-appropriate information about different types of drugs, their harmful effects on the body and mind, and the social and legal consequences of drug abuse. Students are informed about substances such as alcohol, tobacco, cannabis, inhalants, and other narcotic drugs. Through classroom discussions, audiovisual materials, and interactive sessions, students learn how drugs affect brain functioning, academic performance, and personal relationships. Proper knowledge helps students understand the risks involved and reduces curiosity or misconceptions about drug use. Life skills education is another essential element of school-based prevention programmes. Life skills help students develop the ability to deal effectively with the challenges and pressures of everyday life. Adolescents often face peer pressure, emotional stress, and social expectations that may push them toward experimenting with drugs. Life skills training focuses on developing skills such as decision-making, problem-solving, critical thinking, effective communication, self-awareness, empathy, coping with stress, and resisting peer pressure. When students possess these skills, they are more confident and capable of refusing drugs and making healthy choices. Peer education programmes are widely used in school-based drug prevention strategies. In these programmes, selected students are trained as peer educators who help spread awareness about drug abuse among their classmates. Adolescents are often more comfortable discussing sensitive issues with their peers rather than with teachers or adults. Peer educators conduct group discussions, workshops, role plays, and awareness campaigns within the school. They also act as role models by promoting healthy behaviors and discouraging drug use. Peer education helps create a supportive environment where positive attitudes toward drug-free living are encouraged. Teacher training is another important component of school-based prevention programmes. Teachers interact with students on a daily basis and are often the first to notice behavioral or emotional changes that may indicate substance use. Training programmes help teachers understand the signs and symptoms
