Substance abuse problems occur when individuals misuse drugs or alcohol, leading to negative effects on their health, relationships, and daily life. This can include addiction, where a person feels a strong craving for the substance and struggles to control their use, despite harmful consequences. Common substances involved in abuse include alcohol, prescription medications, and illegal drugs like cocaine or heroin. These problems can affect anyone, regardless of age or background, and often require professional help for recovery. Treatment options may include therapy, support groups, and medical intervention to help individuals regain control of their lives.
