What Is Drug and Alcohol Abuse?

Drug and alcohol abuse is a serious public health issue that affects individuals, families, schools, and communities worldwide. It occurs when a person uses drugs or alcohol in a way that is harmful to their health, relationships, education, or work. While some substances may be legally available, misuse can lead to addiction, physical and mental health problems, and long-term life consequences.

Understanding Drugs and Alcohol

Drugs are substances that change how the body and brain function. They can be legal or illegal.

• Legal substances include alcohol, tobacco, and prescription medications.
• Illegal substances include drugs such as marijuana, cocaine, heroin, and methamphetamine.

Alcohol is one of the most commonly abused substances worldwide. According to the World Health Organization (WHO), harmful use of alcohol contributes to millions of deaths each year and is linked to over 200 disease and injury conditions.

What Is Drug and Alcohol Abuse?

Drug and alcohol abuse happens when a person:

• Uses substances excessively.
• Uses substances in risky situations (e.g., driving under the influence).
• Cannot control or stop using the substance.

Abuse can gradually develop into addiction, also known as substance use disorder, where the body and brain become dependent on the substance.
