Understanding Marijuana

Learn about marijuana and substance abuse

Marijuana, commonly known as pot or weed, is a drug made from the dried cannabis plant. Its active ingredient, delta-9-tetrahydrocannibinol or THC, is a psychoactive substance that can induce altered sensory and perceptual experiences, feelings of relaxation and euphoria, excessive laughter, memory and motor impairment, and occasionally anxiety, depression, or social withdrawal. Because of the pleasurable feelings marijuana use can provide, people may have trouble stopping once they have started using the drug.

There are a number of methods for ingesting marijuana. It is typically smoked or the vapors are inhaled using vaporizers, yet it can also be cooked into foods and eaten or brewed into a tea. Another increasingly popular method of consumption is by smoking or eating resins extracted from the marijuana plant, though these resins can have dangerously high concentrations of THC. Although recreational marijuana use has been legalized in a number of states, marijuana continues to be a dangerous drug with the potential to cause long-term harm to those who use it, possibly including permanent cognitive impairment, respiratory damage, and exacerbation of existing mental health problems, not to mention social and occupational difficulties.

Thankfully, marijuana abuse does not have to control a person’s life. With the help of comprehensive care provided by a caring and expert treatment team, it is possible to break free from the grip of marijuana abuse and live a life free from the influence of this insidious drug.

Statistics

Marijuana abuse statistics

According to data from the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, cannabinoids, or the drug family to which marijuana belongs, are the most widely used illicit drugs in the United States. In a given year, approximately 1.5 percent of adults use these drugs. People aged 18 to 29 are the most likely to use this substance, and men are nearly three times more likely than women to use it.

Causes and Risk Factors

Causes and risk factors for marijuana abuse

While it can be difficult to determine exactly what causes a person to abuse marijuana, researchers have uncovered a number of genetic, environmental, and temperamental influences that may increase a person’s risk for abusing the drug, such as:

Genetic: Like many mental health concerns, the risk of cannabis use tends to run in families, and research suggests that genes strongly influence someone’s risk for developing cannabis use disorder. Generally speaking, a person whose parents use marijuana is more likely to use marijuana him or herself.

Environmental: In addition to genetics, a person’s environment can also influence his or her risk for developing cannabis use disorder. Examples of environmental factors that may contribute to use can include previous academic difficulties, use of tobacco, low socioeconomic status, unstable family environment, family history of substance use, history of abuse, and ready availability of marijuana.

Risk Factors:

  • History of antisocial personality disorder, childhood conduct disorder, or disruptive behaviors
  • Disinhibited personality
  • Family history of substance abuse
  • Being a victim of abuse
  • Low socioeconomic status
  • Personal history of substance use
