Marijuana Dependence

One of the most identified psychoactive substance is a plant with. It contains a chemical called tetrahydrocannabinol or THC. It produces a feeling of “high” when taken. The “bud” of the plant contains the higher levels of THC.

This substance is commonly smoked in a pipe. It could also be smoked in blunts, which are cigars that have been emptied of tobacco leaf used to wrap the cigar. This makes the marijuana more potent because it is being combined. The marijuana plant can also be brewed as a tea. When marijuana is smoked, it goes quickly into the blood through the lungs and then to the brain. The “high” sense is felt within a few minutes and could last up to five hours. When marijuana is consumed, it is immersed slowly for the reason that it has to the pass the stomach and intestine for absorption. The shifting feeling could take up an hour but would last longer, for about twelve hours.

How does THC works in the brain? It actually attaches on a specific site in the brain known as the cannabinoid receptor which influences the activities of the nerve cells. Some brain areas have many cannabinoid receptors; others have little or none. Many cannabinoid receptors are found in the areas of the brain that control pleasure, recollection, thought, concentration, sensory and time perception, and coordinated movement. Cannabinoid receptors are mostly concentrated in the hypothalamus, amygdale, spinal cord, brain stem, central gray, and nucleus of the solitary tract. These brain areas are most likely affected with THC, thus will cause a dysfunction in behaviors related to these areas. THC stimulates the reward system of the brain which causes the release of dopamine, which in turn is responsible for the “high” feeling.

With repeated use of marijuana, the body becomes tolerant to the substance. Just like any other abused substances, marijuana could cause withdrawal symptoms when usage is terminated. When the body tolerates the substance, higher doses is required, and in turn, causing more damage in the person’s life. The person wouldn’t stop taking in the drug in order to avoid withdrawal symptoms. This behavior, then, results to marijuana addiction. Marijuana is considered as both mentally and emotionally addictive. Users believe that they need to take marijuana to live normally and to have fun.

Marijuana could change anyone for the duration of the use. It can affect one’s state socially, emotionally, physically, and even psychologically.

It is rooted in their minds that they could not do things without being stoned of smoking marijuana first. They believe that smoking marijuana could explain all their problems. Moreover, as indicated by how the brain is affected with marijuana, memory and cognition is very much affected. Studies have revealed that intense users have difficulty sustaining attention, shifting attention to meet the demands of the changes in the surroundings, and in registering, processing, and using information. It has been recommended that the bigger impairment among heavy users is likely due to an change of brain activity given of by marijuana. In addition, smoking marijuana could lead to abnormal functioning of lung tissue and other respiratory problems.

Marijuana can either be addictive or not. For people with dependency tendency, then yes, marijuana could be addictive. However, there are people who squabble that they can take or leave it and have stop for a long duration. Well, probably, in their case, the answer is no.

Like any other drugs, marijuana may have something positive to give to humanity, however, when humans tend to abuse it, it becomes the evil hand that stirs your mind into something you couldn’t imagine.
