Introduction

Common hemp

Cannabis (/ˈkænəbɪs/) is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: Cannabis sativa, C. indica, and C. ruderalis. Alternatively, C. ruderalis may be included within C. sativa, all three may be treated as subspecies of C. sativa, or C. sativa may be accepted as a single undivided species. The genus is widely accepted as being indigenous to and originating from Asia.

The plant is also known as hemp, although this term is often used to refer only to varieties of Cannabis cultivated for non-drug use. Cannabis has long been used for hemp fibre, hemp seeds and their oils, hemp leaves for use as vegetables and as juice, medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fibre. Various cannabis strains have been bred, often selectively to produce high or low levels of tetrahydrocannabinol (THC), a cannabinoid and the plant's principal psychoactive constituent. Compounds such as hashish and hash oil are extracted from the plant. (Full article...)

Kentucky was the greatest producer of hemp in the United States during the 19th and 20th centuries, when it was the source of three fourths of U.S. hemp fiber. Production started to decline after World War I due to the rise of tobacco as the cash crop in Kentucky and the foreign competition of hemp fibers and finished products. In 1970, federal policies virtually banned the production of industrial hemp during the war on drugs saying all Cannabis sativa is a Schedule I controlled substance. Federal law under the Agricultural Act of 2014 allowed research back into hemp. Kentucky began production again with 33 acres in 2014. As of the 2016 harvest season, only two U.S. states other than Kentucky had over 100 acres (40 ha) in hemp production: Colorado and Tennessee. The first 500-acre commercial crop was planted in Harrison County in 2017, and research permits were issued for over 12,000 acres (4,900 ha) that year. The 2016 documentary Harvesting Liberty concerns the 21st century Kentucky hemp industry. (Full article...)

Hashish (often shortened to hash, and also referred to by countless slang terms such as chocolate) is a psychoactive drug derived from the Cannabis sativa plant. It is solid, of varying hardness and pliability, softening under heat. Its colour can vary from reddish brown to black, and can also be greenish or golden. It is usually smoked in pipes, and sometimes in joints mixed with tobacco or Cannabis buds. It can also be added to cookies or other food and ingested. Hash is used for its relaxing and mind-altering effects. Many people have claimed that using it gives them great insights.
