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...)

"Weed the People", officially "Weed the People: A Cannabis Legalization Celebration", was an event held in Portland on July 3, 2015, two days after recreational marijuana became legal in the U.S. state of Oregon. Sponsored by the Portland Mercury and two cannabis companies, the event was attended by an estimated 1,500–2,000 people, who were provided up to seven grams of marijuana for immediate consumption or to take home. Organizers complied with restrictions on recreational sales by distributing free cannabis and required attendees to pay an entry fee. More than 1,300 tickets were sold, but the building's 500-person capacity meant long wait times to enter. Media outlets reported on the historic nature of the event, which was described as a "stoner's paradise" and a celebration of freedom. (Full article...)

Cannabis indica has a higher ratio of CBD:THC compared to Cannabis sativa. Cannabis strains with relatively high CBD:THC ratios are less likely to induce anxiety than vice versa. The effects of sativa are well known for its cerebral high, while indica is well known for its sedative effects which some prefer for night time use. Both types are used as medical cannabis. Indica plants are normally shorter and stockier than sativas. They have wide, deeply serrated leaves and a compact and dense flower cluster. The effects of indicas are predominantly physical and sedative.

“

Why use up the forests which were centuries in the making and the mines which required ages to lay down, if we can get the equivalent of forest and mineral products in the annual growth of the hemp fields?
