Signs and Symptoms of Marijuana Abuse

Youth Care Treatment Center and school has helped teens with marijuana abuse all over the United States for 30 years. Our unique approach is based off of solid morals and beliefs to help adolescents be successful in turning their lives around.

Understanding Marijuana Abuse

Learn about marijuana abuse and substance abuse

Marijuana, which is more often known as weed or pot, is a substance that when smoked or eaten brings about feelings of relaxation, euphoria, and detachment from one’s surroundings. While many might feel that the use of marijuana is harmless, the truth is that the use of this substance can damage the overall function of one’s brain, and when children and adolescents use this substance, it can affect their neurological development. The continued use of marijuana can bring on poor lung functioning, cardiac problems, a decline in learning capabilities, difficulty using sound judgment, and impaired coordination. In addition, when individuals use marijuana and participate in activities such as driving, they place themselves and others at risk because their perception is altered. Keep in mind, however, there are treatment options for marijuana abuse.


Marijuana abuse addiction statistics

Research has shown the over the past six years, the amount of adolescents who use marijuana has increased significantly. According to recent studies, roughly 7% of 8th graders, 18% of 10th graders, and 23% of 12th graders have used marijuana within the month prior to the collection of data. Other studies show that over 6% of high school students use marijuana daily.

Causes and Risk Factors

Causes and risk factors for marijuana abuse

Similar to the use of other illicit substances, experts have yet to determine the specific reason or reasons that some people use marijuana while others do not. Instead, it is believed that a number of factors increase one’s risk of marijuana abuse, including:

Genetic: Substance abuse and addiction is said to have strong genetic ties, tending to run in families. Children and adolescents who have relatives such as parents and siblings who abuse marijuana are more likely to do so themselves.

Environmental: Children and adolescents who spend time in an environment where marijuana is used frequently or considered acceptable are more likely to start abusing substances than those who do not live in similar environments. In addition, young individuals might use marijuana as a method of self-medicating negative emotions that come from trauma or an existing mental illness.

Risk Factors:

  • Experiencing trauma
  • Lack of parental involvement / poor parenting
  • Easy access to marijuana
  • Peer pressure
  • Family or personal history of mental illness
  • Early exposure to the use of marijuana
  • Family history of substance use
  • Personal history of using other substances

As a parent, I highly recommend Youth Care. We were involved in all aspects of my child's treatment plan, the staff provided a safe and friendly environment, we enjoyed parent day participation and, most importantly, the therapy my child received while at Youth Care was exceptional - pretty much life-changing. My child made more progress there than had been made in years of therapy elsewhere.
