Substance Abuse Information

Substance Abuse

Substance abuse can simply be defined as a pattern of harmful use of any substance for mood-altering purposes. "Substances" can include alcohol and other drugs (illegal or not) as well as some substances that are not drugs at all. "Abuse" can result because you are using a substance in a way that is not intended or recommended, or because you are using more than prescribed.

Substance abuse and problematic patterns of substance use among youth can lead to problems at school, cause physical and mental health-related issues, promote poor peer relationships, cause motor-vehicle accidents, and place stress on the family. They can also develop into lifelong issues such as substance dependence, chronic health problems, and social and financial consequences.

Warning Signs

Many youth may show behaviors in adolescence that are indicative of substance abuse, but can also be considered normal behaviors while growing up. It is important to take notice if there are several signs happening at the same time, if they occur suddenly, and if the behaviors are extreme. The following behaviors in a youth might indicate drug or alcohol abuse:

  • Mood changes (temper flare-ups, irritability, defensiveness)

  • Academic problems (poor attendance, low grades, disciplinary action)

  • Changing friends and a reluctance to have parents/family get to know the new friends

  • A "nothing matters" attitude (lack of involvement in former interests, general low energy)

  • Finding substances (drug or alcohol) in youth’s room or personal effects

  • Physical or mental changes (memory lapses, poor concentration, lack of coordination, slurred speech, etc.)1
