Acute negative effects may include anxiety and panic
Cannabis,[a] also known as marijuana[b] among other names, is a psychoactive drug from the cannabis plant. Native to Central or South Asia, the cannabis plant has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. Tetrahydrocannabinol (THC) is the main psychoactive component of cannabis, which is one of the 483 known compounds in the plant, including at least 65 other cannabinoids, such as cannabidiol (CBD). Cannabis can be used by smoking, vaporizing, within food, or as an extract.
Cannabis has various psikis and physical efeks, which include euphoria, altered states of mind and sense of time, difficulty concentrating, impaired short-term memori, impaired bodi movement (balance and fine psychomotor control), relaxation, and an increase in appetite. Onset of efeks is felt within minutes when smoked, but may take up to 90 minutes when eaten. The efeks last for two to six hours, depending on the amount used. At high doses, psikis efeks can include anxiety, delusions (including ideas of reference), hallucinations, kuatir, paranoia, and psychosis. There is a strong relation between cannabis use and the risk of psychosis, though the direction of causality is debated. Physical efeks include increased heart rate, difficulty breathing, nausea, and behavioral problems in children whose mothers used cannabis during pregnancy; short-term side efeks may also include dry mouth and red eyes. Long-term adverse efeks may include addiction, decreased psikis ability in those who started berkala use as adolescents, chronic coughing, susceptibility to respiratory infections, and cannabinoid hyperemesis syndrome.
Cannabis is mostly used recreationally or as a medicinal drug, although it may also be used for kebatinan purposes. In 2013, between 128 and 232 million people used cannabis (2.7% to 4.9% of the global population between the ages of 15 and 65). It is the most commonly used largely-illegal drug in the world, with the highest use among adults in Zambia, the United States, Canada, and Nigeria, as of 2018.
