Hemp 

Hemp (from Old English hænep) is a commonly used term for high growing varieties of the Cannabis plant and its products, which include fiber, oil, and seed. Hemp is refined into products such as hemp seed foods, hemp oil, wax, resin, rope, cloth, pulp, paper, and fuel.

Other variants of the herb Cannabis sativa are widely used as a drug, commonly known as marijuana. These variants are typically low growing and have higher content of tetrahydrocannabinol (THC). The legality of Cannabis varies widely from country to country, and from state to state in the United States. In many countries regulatory limits for concentrations of psychoactive drug compounds, particularly THC, in hemp require the use of strains of the plant which are bred for low content.

Hemp is used for many varieties of products including the manufacture of cordage of varying tensile strength, durable clothing and nutritional products. The oil from the fruits ("seeds") oxidizes (commonly, though inaccurately, called "drying") to become solid on exposure to air, similar to linseed oil, and is sometimes used in the manufacture of oil-based paints, in creams as a moisturizing agent, for cooking, and in plastics. Hemp seeds have been used in bird seed mix as well.^[2] A survey in 2003 showed that more than 95% of hemp seed sold in the EU was used in animal and bird feed. Hemp seed is also used as a fishing bait.

In modern times hemp is used for industrial purposes including paper, textiles, clothing, biodegradable plastics, construction (as with Hempcrete and insulation), body products, health food and bio-fuel.
