The cannabis sativa plant grows wild throughout most of the tropic and temperate regions of the world.
Cannabis contains chemicals called cannabinoids that are unique to the cannabis plant.
THC is believed to be responsible for most of the characteristic psychoactive effects of cannabis. Their effects are felt within minutes, reach their peak in 10 to 30 minutes, and may linger for two or three hours. The state of intoxification may not be noticeable to an observer. However, driving, occupational, or household accidents may result from a distortion of time and space relationships and impaired coordination. The individual user may experience shifting sensory imagery, rapidly fluctuating emotions, a flight of fragmentary thoughts with disturbed associations, an altered sense of self-identity, impaired memory, and a dulling of attention despite an illusion of heightened insight.
