Drug abuse refers to the harmful or hazardous use of psychoactive substances, including alcohol, prescription medications, and illegal drugs. It often leads to addiction, where individuals feel a compulsive need to consume these substances despite negative consequences on their health, relationships, and daily life. The effects of drug abuse can vary widely, impacting both physical and mental health. Common consequences include overdose, mental health disorders, and increased risk of accidents. Treatment options, such as rehabilitation programs and counseling, aim to help individuals recover and regain control over their lives.
