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.

When marijuana is consumed, it is immersed slowly for the reason that it has to the pass the stomach and intestine for digestion. The altering 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 a small number of or none. Many cannabinoid receptors are located in the parts of the brain that control pleasure, memory, contemplation, 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 causing 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.
The continued use of marijuana makes the body to become dependent of the substance. Just like any other abused drugs, 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.

Furthermore, as indicated by how the brain is affected with marijuana, memory and cognition is very much affected. Studies have revealed that heavy users have trouble sustaining attention, changing 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 alteration of brain activity produced by marijuana. In addition, smoking marijuana could lead to abnormal functioning of lung tissue and other respiratory problems.
The plant marijuana has the capability to make you an addict or not. For people with addictive tendency, then yes, marijuana could be addictive. However, there are people who squabble that they can take or leave it and have quit for a long duration. Well, probably, in their case, the answer is no.
