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.

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.
