Introduction

Cannabis sativa
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...)

Oregon's Cannabis Universal Symbol

Cannabis in Oregon is legal for both medical and recreational use. In recent decades, the U.S. state of Oregon has had a number of legislative, legal, and cultural events surrounding use of cannabis (marijuana, hashish, THC, kief, etc.). Oregon was the first state to decriminalize the possession of small amounts of cannabis, and among the first to authorize its use for medical purposes. An attempt to recriminalize possession of small amounts of cannabis was turned down by Oregon voters in 1997.

From 1999 through 2005, the ratio of Oregonians using cannabis outpaced the general United States population by 32–45%. In surveys conducted in 1974 and 1975—one and two years after decriminalization—it was found that 2% of respondents said they did not use marijuana or cannabis because they were unavailable, 4% for legal or law enforcement reasons, 53% reported lack of interest, and 23% cited health dangers. The remaining 19% were using or had used it at one time. (Full article...)
