Signs and Symptoms of Marijuana Addiction

Marijuana, also referred to as grass or dope, is a grey-green mixture of dried, shredded flowers and leaves of the hemp plant. Individuals use pot for its psychoactive and physiological effects, which include heightened mood, relaxation and increased appetite. The main active ingredient in pot that is responsible for the associated high is THC (delta-9-tetrahydrocannabinol).There are a number of ways a person can abuse marijuana: the loose marijuana can be rolled into joints, smoked through a bong, or mixed into certain foods and eaten.

Most people who abuse marijuana combine it with other types of drugs to heighten an existing intoxication or reduce more unpleasant symptoms. Marijuana can be combined with traditional downers, such as alcohol, heroin, or opiates to increase feelings of sedation and well-being. Additionally, many people combine marijuana with stimulants such as Adderall, cocaine, or methamphetamines.


Marijuana is the most commonly used illicit drug in the United States today. Over 94 million people in the United States have disclosed that they’ve used marijuana at least once. Daily marijuana usage has increased among 8th, 10th, and 12th graders. In 2010, it was estimated that 21.4% of high school seniors admitted to smoking pot in the previous 30 days. Girls and boys reported similar usage rates, with 10.1% of boys and 9.7% percent of girls between the ages of 12 and 17 reporting pot use. Approximately 17% of individuals who smoked pot before the age of 12 become addicted and are among daily users (25%-50% of daily users began smoking at a young age).

Causes and Risk Factors for Marijuana Abuse

Through years of research, it is widely recognized that addiction to drugs or alcohol is not caused by a single factor, but due to genetic, environmental, and physical factors working together. The causes for marijuana addiction may include the following:

Genetic: There is a well-established relationship that shows that people who have a first-degree relative, such as a parent or sibling, who have struggled with addiction, are at a higher risk for developing an addiction themselves.

Physical: Many times individuals will use drugs as a way to self-medicate and cope with the overwhelming symptoms of undiagnosed or untreated mental health problems. Chronic usage of drugs or alcohol can lead to changes in the structure and function of the brain, which can lead to addiction.

Environmental: People who grow up in a home in which drugs are used as a way of coping with stress learn that drugs and alcohol are the best way to deal with the challenges of life. When faced with stressful situations later in life, these individuals are more likely to turn to drugs.

Risk Factors:

  • Peer pressure
  • Untreated mental illnesses
  • Addiction potential of drug
  • High levels of stress
  • Improperly developed coping skills
  • Being male
