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.
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...)
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.
