About plant names...
Marijuana has a long history as an intoxicant. Its seeds are a source of oil, producing all the amino
acids needed for human life, and are gradually becoming more widely used in foods. This species of
marijuana produces fibers that are used to create rope.
Identification: The palmlike shape of marijuana leaves has become
iconic. Plants reach 16' (5 m) in height. Leaves are up to 4" (10 cm) long and ½" (1.5 cm) wide. The small white flowers are inconspicuous.
From Köhler, Franz Eugen, Medizinal-Pflantzen, Gera-Untermhaus, FE Köhler, 1887
Only this species is suitable for rope production. Both this and C. indica are used as intoxicants.

Edibility: Marijuana’s primary psychoactive ingredient,
survives cooking and is often eaten as an alternative to smoking. So the leaves and flowers are edible,
but not a practical food source unless you are out of work or independently wealthy. Marijuana seeds, which are almost free of THC, are a minor but increasingly popular
Medical: Marijuana’s ability to stimulate the appetite has been found to
reduce symptoms of nausea in cancer patients undergoing chemotherapy or suffering from other illnesses.
Some states have legalized the use of “medical marijuana.”
