No one experiences marijuana abuse the same way as someone else. Understanding the signs, symptoms and side effects of marijuana abuse is a key component toward starting the recovery journey.
Understanding Marijuana Abuse
Learn about marijuana abuse and substance abuse
Marijuana, also called “pot,” “weed,” and “grass,” is a dried and shredded mixture of the leaves, stems, and seeds that come from the hemp plant Cannabis sativa. The primary mind-altering chemical that produces the effects associated with marijuana use is called delta-9-tetrahydrocannabinol, or as it’s more commonly known, THC.
Marijuana can be used in many ways. Most commonly, teens roll the shredded dried mixture into “joints,” or marijuana cigarettes, and smoke them. Others will smoke pot by using a glass water pipe, or “bong,” or a regular glass pipe. When marijuana is inhaled, this illegal substance produces mind-altering effects. THC, the psychoactive component of marijuana, passes through the lungs and into the bloodstream. When this happens, the cannabinoid receptors in the areas of the brain that influence pleasure, thinking, memory, sensory perception, concentration, time perception, and movement become over-stimulated, leading to feelings of intoxication.
Growing in popularity, another way to abuse pot are “edibles,” or marijuana baked into foods. This allows for a similar, more laid back high achieved without inhaling the harsh smoke produced by smoking weed. While edible marijuana is growing in popularity, marijuana is absorbed more slowly when ingested in food or drink. When an adolescent or teen is high on pot, they may have distorted perceptions, impaired coordination, and difficulties thinking and problem solving, as well as distorted learning and memory.
Marijuana is becoming increasingly potent, meaning that the amount of THC in a bag of weed is becoming stronger and stronger. First-time users may experience increasing amounts of adverse effects. Contrary to popular belief, marijuana is an addictive substance that leads to consequences the longer it is abused.
Marijuana abuse statistics
Marijuana is the most commonly used illicit drug in the United States – over 94 million people in the United States have admitted using marijuana at least once. Daily marijuana usage has increased over the years among 8th, 10th, and 12thgraders. 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.
Many people who use marijuana become addicted. Approximately 17% of individuals who smoked pot before the age of 12 become addicted and are among 25% to 50% of daily users.
According to the Drug Enforcement Administration (DEA), an enormous percentage of those arrested for crimes test positive for marijuana. After alcohol, marijuana is the second most frequently found substance in the bodies of the drivers involved in fatal car accidents.
Causes and Risk Factors
Causes and risk factors for marijuana abuse
It’s thought that addiction is the result of a number of factors working together simultaneously, instead of just one particular cause. The causes for marijuana addiction may include the following:
Genetic: It’s been well-established that individuals who have a relative – especially a first-degree relative, such as a parent or sibling – with a past or present addiction problem are at greater risk for developing an addiction themselves. This means that should an adolescent decide to start using pot, they have a greater risk for developing an addiction to it.
Physical: Most individuals who abuse drugs do so to increase the levels of certain pleasure-releasing neurotransmitters in the brain, such as dopamine. After prolonged drug abuse it changes the structure and function of the brain, which prevents the brain from being able to naturally produce feelings of pleasure. This can lead to individuals continuing to abuse drugs and the development of an addiction.
Environmental: Individuals who begin to abuse drugs at younger ages are more prone to develop an addiction in later life. Many of these individuals begin to use marijuana as the first drug of abuse and may go on to develop addictions to other, harsher drugs, such as heroin or cocaine.
- Being male – boys are twice as likely as girls to develop addiction
- Having a mental illness, such as depression, ADHD, or other illnesses
- Peer pressure
- Addiction potential of the substance abused
- High levels of stress
