          The first short-term effect is the loss of short-term memory. Marijuana is found to be contained a substance called Delta-9-tetrahydrocannabinol (THC). When it interacts with cannabinoid receptors in the brain, it damages the brain’s function. The areas of the brain with more cannabinoid receptors are heavier impacted.

An example place of the brain that contains cannabinoid receptors is the hippocampus. The hippocampus is responsible for short-term memory. It is located in the medial temporal lobe of the brain. By using marijuana, you can stop yourself from remembering a collection of recent events. Marijuana also affects the level of dopamine. Dopamine is a chemical that plays several important roles in your brain.

For example, one of its roles is to prevent the released of breast milk. Having too much dopamine causes mental disorder in which thoughts and emotions are damaged. On the others hand, low level of dopamine causes depression and difficulty to handle stress. A few more common short-term effect is impaired motor skills, mood alterations short-term memory problems, and trouble thinking clearly and solving problems.          Marijuana also has some long-term effects on our brains, especially on some people that their brains aren’t fully developed. According to the National Institute on Drug Abuse, if the users use marijuana from a very young age and continue it into adulthood they might end up in losing 1 to 3 IQ points that are not recoverable, even though when they stop using marijuana.

If a person uses marijuana in adolescence, that person will likely going to be addicted to marijuana as an adult. As a person gets older, neurons in the hippocampus naturally lose. Marijuana acts as a booster. It hustles this process. Losing neurons causes long-term memory problems, weakened coordination, learning issues and sleep problems. Another research from National Institute on Drug Abuse shows that marijuana can have schizophrenia in those who are genes issues.

Schizophrenia is a long-term mental disorder. Breathing and respiration problems and chronic cough are additional consequences of using marijuana. Moreover, marijuana can disrupt heart rhythms and normal cardiac function.          To conclude, marijuana can affect the brain by 2 ways, short and long-term. Some of the short-term effects are impaired motor skills, mood alterations, short-term memory problems, and trouble thinking clearly and solving problems. Some of the long-term effects are an addiction, losing IQ points, weakened coordination, learning issues, sleep problems and losing long-term memory problem.

Marijuana can only affect the brain long and short-term; however, it can’t affect our brain permanently.  * * * * * * * * * * * * * *Works CitedDeans, Emily. “Dopamine Primer.” Psychology Today, Sussex Publishers, 13 May 2011,
