What is cannabis?

Cannabis is the most durable of the hemp plants, and it produces the toughest cloth, called "canvass". (Canvass was widely used as sails in the early shipping industry, as it was the only cloth which would not rot on contact with sea spray.) The cannabis plant also produces three other very important products which the other hemp plants do not (in usable form, that is): seed, pulp, and medicine.

The pulp is used as fuel, and to make paper. The seed is suitable for both human and animal foods. The oil from the seed can be used in as a base for paints and varnishes. The medicine is a tincture or admixture of the sticky resin in the blossoms and leaves of the hemp plant, and is used for a variety of purposes.
