The Indian hemp plant plant Cannabis sativa syn. Cannabis Indica. See Cannabis Indica, below. [PJC]
Cannabis Indica(/), the Indian hemp, now considered a variety of the common hemp (Cannabis sativa), originating in Asia but now grown widely around the world. It can be formed into a tough fiber that is used to make rope and tough fabric. The dried leaves and female flowers are smoked or chewed by people to produce a euphoric or hallucinogenic effect, caused mainly by the substance tetrahydrocannabinol (THC) contained in it. The THC-containing products of Cannabis are classified as a controlled substance, and posession and sale are illegal in most states of the United States. Once classified as a narcotic, the plant is now more commonly referred to in the category of euphoric or hallucinogenic agents.
