Alcohol and drug abuse refers to the excessive, habitual, or inappropriate use of substances that negatively affect the brain and body functions. It results in loss of control, dependency, and inability to perform normal daily activities. Such abuse not only harms the individual’s health but also impacts family, academics, and society. Long term use can lead to addiction, which is difficult to overcome. Addiction is the feeling of wanting more and more of the substance. People become habituated to this sense of joy and as a result, they take more drugs to feel better or even when they are not needed
The causes of substance abuse are many. Peer pressure is a major reason among adolescents, where friends may influence one to experiment. Stress, anxiety, and depression often push individuals to seek relief through drugs or alcohol. Genetic predisposition can increase vulnerability to addiction. Easy availability of substances and curiosity about their effects also contribute. Lack of guidance and weak family support further enhance the risk.
The effects of alcohol and drug abuse are both short-term and long-term. In the short term, it impairs judgment, senses, and motor coordination, leading to accidents or poor performance. Continuous use leads to dependency and addiction, making it hard to quit. Long-term abuse causes damage to the liver, lungs, heart, and brain, and weakens the immune system. It also results in academic decline, loss of relationships, and social stigma.
Prevention of substance abuse requires a multi-dimensional approach. Education and awareness programs in schools help students understand the risks early. Parental guidance and involvement play a crucial role in monitoring behavior. Counselling and mental health support provide coping mechanisms for stress. Governments must enforce strict laws and policies to limit the availability of harmful substances. A supportive environment with positive peer influence and healthy activities also reduces risk.
