Introduction

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, Cannabis indica, and Cannabis ruderalis; C. ruderalis may be included within C. sativa; or all three may be treated as subspecies of a single species, C. sativa. The genus is indigenous to central Asia and the Indian subcontinent.

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, for hemp oils, for medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fiber. To satisfy the UN Narcotics Convention, some cannabis strains have been bred to produce minimal levels of tetrahydrocannabinol (THC), the principal psychoactive constituent. Many plants have been selectively bred to produce a maximum of THC (cannabinoids), which is obtained by curing the flowers. Various compounds, including hashish and hash oil, are extracted from the plant.

Globally, in 2013, 60,400 kilograms of cannabis were produced legally. In 2014 there were an estimated 182.5 million cannabis users (3.8% of the population aged 15–64). This percentage has not changed significantly between 1998 and 2014.

Cannabis in Oregon relates to a number of legislative, legal, and cultural events surrounding use of cannabis (marijuana, hashish, THC, kief, etc.). Oregon was the first U.S. 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. In 2012, the Oregon Cannabis Tax Act, an initiative to allow personal marijuana and hemp cultivation and use without a license was defeated in a state ballot.

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.
