Understanding Marijuana Addiction

Learn about marijuana addiction

Marijuana comes from a dried mixture of the flowers, seeds, and stems of the cannabis plant or from man-made cannabinoids called synthetic marijuana that are typically dried, shredded plant materials that have been sprayed with mind-altering chemicals. Tetrahydrocannabinol, also known as THC, is the main active ingredient in marijuana and is what causes people to experience the “high” associated with smoking marijuana or consuming it in other forms. THC acts much like the cannabinoid receptors in the brain, which are responsible for thinking, memory, coordination, pleasure, and a person’s perception of time. When an individual consumes marijuana, whether through smoking it, eating it in foods or candies, or absorbing it in their skin through balms and oils, the THC tells their brain to release dopamine, which might make them feel euphoric and can potentially interfere with how their brain processes information.

Although marijuana might seem harmless, it can actually be an addictive substance that can cause significant health risks. Long-term marijuana use can impair learning and cause memory problems and many different behavioral challenges. People who abuse marijuana might also be at a higher risk of lung and breathing problems, as well as heart attack and stroke. But by recognizing the signs and symptoms of marijuana addiction, you or your loved one can seek professional treatment before the continued use of this substance may cause any harmful long-term effects.
