Cannabis (/ˈkænəbɪs/ⓘ) is a genus of flowering plants in the family Cannabaceae that is widely accepted as being indigenous to and originating from the continent of Asia. However, the number of species is disputed, with as many as three species being recognized: Cannabis sativa, C. indica, and C. ruderalis. Alternatively, C. ruderalis may be included within C. sativa, or all three may be treated as subspecies of C. sativa, or C. sativa may be accepted as a single undivided species.
The plant is also known as hemp, although this term is usually used to refer only to varietiescultivated for non-drug use. Hemp has long been used for fibre, seeds and their oils, leaves for use as vegetables, and juice. Industrial hemp textile products are made from cannabis plants selected to produce an abundance of fibre.
CHS is associated with frequent (weekly or more often), long-term (several months or longer) cannabis use; synthetic cannabinoids can also cause CHS. The underlying mechanism is unclear, with several possibilities proposed. Diagnosis is based on the symptoms; a history of cannabis use, and ruling out other possible causes of hyperemesis (persistent vomiting). The condition is typically present for some time before the diagnosis is made. (Full article...)
Joint is a slang term for a cigarette rolled using cannabis. Rolling papers are the most common rolling medium in industrialized countries; however, brown paper, cigarettes with the tobacco removed, beedis with the tobacco removed, tracing paper, ATM receipts and newspaper are commonly used in some developing countries, and by poorer smokers in first world countries. Modern papers are now made in a range of sizes from a wide variety of materials including rice, hemp, and flax, and are also available in flavored varieties. A joint can vary in size, typically containing between 0.25 to 1 grams net weight of cannabis (joints have been rolled with 2 or more pounds but this is not a common practice) (depending on whether tobacco is used in the rolling process).

... that according to his memoirs, Howard Marks concluded a drug deal at the Warwick Castle with half a consignment of Thai grass hidden in a car parked outside?
The illegality of cannabis is outrageous, an impediment to full utilization of a drug which helps produce the serenity and insight, sensitivity and fellowship so desperately needed in this increasingly mad and dangerous world.
