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...)

In the United States, increased restrictions and labeling of cannabis (legal term marijuana or marihuana) as a poison began in many states from 1906 onward, and outright prohibitions began in the 1920s. By the mid-1930s cannabis was regulated as a drug in every state, including 35 states that adopted the Uniform State Narcotic Drug Act. The first national regulation was the Marihuana Tax Act of 1937.

Cannabis was officially outlawed for any use (medical included) with the passage of the 1970 Controlled Substances Act (CSA). Multiple efforts to reschedule cannabis under the CSA have failed, and the U.S. Supreme Court ruled in United States v. Oakland Cannabis Buyers' Cooperative and Gonzales v. Raich that the federal government has a right to regulate and criminalize cannabis, even for medical purposes. Despite this, states and other jurisdictions have continued to implement policies that conflict with federal law, beginning with the passage of California's Proposition 215 in 1996. By 2016 a majority of states had legalized medical cannabis, and in 2012 the first two states, Colorado and Washington, legalized recreational use. (Full article...)

“

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.
