Effects of Marijuana on the Brain

Cannabis Sativa is the hemp plant that provides us with marijuana, better known as weed to us. It is the most popular illegal drug in the world. It has been used for both, recreational and medical purposes, for centuries. But, the effects of it are mixed and puts it in a grey area. The hypothesis that marijuana possesses innumerable medical qualities that can provide us cure for many incurable diseases has been propounded over, time and again. Extensive research needs to be done in this area to arrive at a conclusion. Let us take a look at the effect that marijuana has over the Brain and the body.

  • It Gets the Neurons Firing.

Marijuana has at least 60 types of cannabinoids. Its effect on our brain is to keep our neurons firing, magnifying our thoughts and perception and keeping us fixed on them. This is the reason why when you smoke up you tend to focus on one thought until you are distracted by another one. Cannabinoids also affect the levels of dopamine in our brain, often resulting in a sense of relaxation and euphoria, providing with the feeling of high.

  • It Affects the Memory.

In some cases, a heavy smoker would develop issues with short term memory, that is, amnesia. It involves certain other factors as well, including the amount and how often a person smokes-up. The research so far shows that even though marijuana usage has no effect on the cognitive abilities of the body, it tampers with the short term memory of the smoker.


  • It Changes Ones’ Mood.

Smoking marijuana changes ones’ mood. It causes relaxation. Some users experience heightened sensory perception, with colors appearing more vivid and noises being louder. For some, marijuana can cause an altered perception of time and increased appetite, known as the “munchies.”

  • It Might Not Always be a Pleasurable Experience.

Smoking weed can go horribly wrong at times. Smoking up is dangerous for people suffering from anxiety as they might start feeling paranoid. Feelings of panic and fear might haunt them for hours. Hallucinations are another risk factor. The psychoactive elements of the drug lead the mind to hallucinate and see things that are not there in reality. The person might find it incredibly difficult to concentrate. It also impairs bodily co-ordination for a while.

  • It Affects the Brain Lesser than Other Drugs.

Marijuana is categorized as Schedule 1 Drug. It is highly addictive. However, they affect the brain lesser than other drugs such as cocaine and ecstasy.

Smoking-up might be a taboo but, it is not totally bad for ones’ health. Smoking weed in limited quantity and occasionally, provides with relaxation and the good sort of high. However, one should not make a habit out of it since the long term effects of it are still unknown.
