but where marihuana is made up of blooming tops and foliages.The chief active chemical in marihuana is THC ( delta-9-tetrahydrocannabinol ) . The membranes of certain nervus cells in the encephalon contain protein receptors that bind to THC. Once firmly in topographic point. THC initiates a series of cellular reactions that lead to the high that users experience when they smoke marihuana. There are normally stages in marihuana usage there are: poisoning. initial stimulation.
which includes silliness and euphory. followed by sedation and pleasant repose. Temper alterations are frequently accompanied by altered perceptual experiences of clip and infinite. Thinking processes become disrupted by fragmental thoughts and memories. Other feelings include increased appetite.

Smoking marihuana can damage the lungs. and long-run usage may increase the hazard of lung malignant neoplastic disease. Even infrequent usage of marihuanas can do combustion and stinging of the oral cavity and pharynx. frequently accompanied by a heavy cough.
Person who smokes marijuana on a regular basis may hold many of the same respiratory jobs that tobacco tobacco users do. such as day-to-day cough andfrequent chest unwellness. a heightened hazard of lung infections. and a greater inclination to obstructed air passages.
Cancer of the respiratory piece of land and lungs may besides be promoted by marijuana fume.Marijuana usage has the possible to advance malignant neoplastic disease of the lungs and other parts of the respiratory piece of land because it contains thorns and carcinogens. Marijuana smoke contains 50 to 70 per centum more carcinogenic hydrocarbons than does tobacco fume.
It besides produces high degrees of an enzyme that converts certain hydrocarbons into their carcinogenic signifier. degrees that may speed up the alterations that produce malignant cells. Marijuana users normally inhale more deeply and keep their breath longer than baccy tobacco users do. which increases the lungs exposure to carcinogenic fume. Some other effects of marihuana may happen because THC impairs the immune system’s ability to contend off infective diseases and malignant neoplastic disease. In research lab experiments that exposed animate being and human cells to THC or other marijuana ingredients. the normal disease-preventing reactions of many of the cardinal types of immune cells were inhibited. In other surveies.

and passing work clip on personal affairs.Although no medicines are presently available for handling marihuana maltreatment. recent finds about the workings of the THC receptors have raised the possibility of finally developing a medicine that will barricade the intoxicating effects of THC. Such a medicine might be used to forestall backsliding to marijuana maltreatment by decreasing or extinguishing its entreaty.
