Understanding Marijuana

Learn about marijuana and substance abuse

An illicit drug that can be smoked, brewed, or mixed with food is marijuana. Also know as pot, weed, bud, or dope, marijuana contains a mind-altering chemical known as delta-9-tetrahydrocannabinol, which is believed to cause the associated high and hindered brain functioning when a person uses this substance. Children and adolescents who use marijuana often experience feelings of relaxation and detachment from the world around. Oftentimes, these sensations can come at the expense of how a youth performs at school, home, and in the community. Additionally, there are a number of health risks that are involved with ongoing use of marijuana and individuals who use this substance are frequently at risk for developing symptoms synonymous with a mental health condition. Ceasing use of this drug can prevent these adverse effects from happening. Lastly, children and adolescents who receive care for this type of substance abuse problem are known to have improved performance in school and can go on to develop into fully functioning and well-adjusted adults.

Statistics

Marijuana addiction statistics

Studies that examined the prevalence of marijuana use among children and adolescents have concluded that the use and/or abuse of this drug is high among young people. One such study found that over 6% of high school-aged youth use this substance on a daily basis. Another study found that 7% of 13 and 14 year olds, 18% of 15 and 16 year olds, and 23% of 17 and 18 year olds have used this harmful substance in the last month. Sadly, research suggests that these estimates will continue to rise among younger individuals.

Causes and Risk Factors

Causes and risk factors for marijuana addiction

Addiction specialists and researchers agree that a number of influences can ultimately determine whether or not a person will use or abuse marijuana. Consider the following explanations for the causes and risk factors of marijuana use:

Genetic: A substantial amount of research has concluded that a person can have a genetic predisposition to the development of a substance abuse problem. Especially in those who have a first-degree family member with chemical dependency concerns, there is a high likelihood that the use and/or abuse of drugs, such as marijuana, will occur. In lieu of this discovery, it can be said that an individual’s genetics can greatly influence the chances a person will abuse substances, including marijuana.

Physical: Cannabinoid receptors, also known as CBRS, are found in every human brain. These receptors are responsible for maintaining coordination, perceptions of time and senses, and the forming and storing of memories within the brain. Additionally, CBRS are in charge of helping a person make good-decisions based on other information that is transmitted in the brain. Individuals who use or abuse marijuana damage these receptors because of their drug use and ultimately hinder the brain’s ability to perform the aforementioned operations. The symptoms that subsequently manifest are those that infer a person is under the influence of marijuana.

Environmental: The environment in which one is raised and other influences can be very impressionable on a child or adolescent. For example, if a young person is exposed to marijuana use at home, there is a higher likelihood that he or she will eventually use this substance. Additionally, if marijuana use is present in a youth’s home or if a young person’s peers are using marijuana, he or she may also use this drug if it is easily accessible. If a child or adolescent lacks the necessary skills to resist substance use, especially if exposure to this drug occurs early in life, the risk for experimentation and eventual abuse increases exponentially.

Risk Factors:

  • Early exposure to marijuana use
  • Peer pressure
  • Lack of appropriate coping skills
  • Family history of substance use or addiction or mental health condition(s)
  • Preexisting mental health condition or conditions
  • Easy access to marijuana
