One of the most identified psychoactive substance is a plant with. This psychoactive plant contains the. This is the one responsible for the “high” feeling when taking marijuana. The flower of the plant contains the higher levels of THC.

Marijuana is usually smoked as a cigarette. 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. Marijuana can also be mixed in food. When marijuana is smoked, it goes fast 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 absorbed slowly for the reason that it has to the pass the stomach and intestine for digestion. The varying feeling could take up an hour but would last longer, for about twelve hours.

In the brain, THC connects to specific sites called cannabinoid receptors on nerve cells and thereby influences the activity of those cells. Some brain areas have many cannabinoid receptors; others have little or none. Many cannabinoid receptors are located in the parts of the brain that control pleasure, memory, 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 areas in the brain are most likely affected with THC, thus causing a dysfunction in behaviors related to these areas. THC activates 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 be a reason of withdrawal symptoms when usage is ended. 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 attitude, 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.

Overtime, marijuana could change the person socially, emotionally, physically, and even psychologically. Users tend to lose motivation in doing activities that used to mean a lot to them. The abuser would then stay away from their friends who do not use marijuana and settle to those who use the substance. 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, changing attention to meet the demands of the changes in the environment, and in registering, processing, and using information. It has been suggested that the bigger impairment among heavy users is likely due to an adjustment of brain activity produced by marijuana. Furthermore, 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 those who argue that they can take or leave it and have stop for a long duration. Well, probably, in their case, the answer is thumbs down.

Marijuana can be beneficial but once abused can give off more harm than good which translates one to call for help.
