Marijuana Abuse Quiz question 2 Effects of Marijuana Abuse Within a few minutes after inhaling marijuana smoke, an individual’s heart rate speeds up, the bronchial passages relax and become enlarged, and blood vessels in the eyes expand, making the eyes look red. The heart rate-normally 70 to 80 beats per minute-may increase by 20 to 50 beats per minute, or may even double.
Delta-9-tetrahydrocannabinol (THC) is the main active ingredient in marijuana, responsible for many of its effects. When marijuana is smoked, THC rapidly passes from the lungs into the bloodstream, which carries the chemical to organs throughout the body, including the brain.
As THC enters the brain, it causes the user to feel euphoric-or high-by acting on the brain’s reward system, which is made up of regions that govern the response to pleasurable things like sex and chocolate. THC stimulates brain cells to release the chemical dopamine. Along with euphoria, relaxation is another frequently reported effect in human studies. Other effects, which vary dramatically among different users, include heightened sensory perception (e.g., brighter colors), laughter, altered perception of time and increased appetite. After a while, the euphoria subsides, and the user may feel sleepy or depressed. Occasionally, marijuana use may produce anxiety, fear, distrust or panic. Marijuana use impairs a person’s ability to form new memories and to shift focus. Therefore, learning, doing complicated tasks, participating in athletics and driving are also affected.
The effects of Marijuana use on the user depend on its strength, or potency, which is related to the amount of THC it contains. The THC content of marijuana has been increasing steadily since the 1970s.
Individuals who become dependent on marijuana tend to be less motivated and less satisfied with their lives. They are also at risk for depression and for abusing alcohol and other drugs.
