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.
A dried cannabis flowerThe short-termeffects of cannabis are caused by many chemical compounds in the cannabis plant, including 113 different cannabinoids, such as tetrahydrocannabinol (THC), and 120 terpenes, which allow its drug to have various psychological and physiological effects on the human body. Different plants of the genus Cannabis contain different and often unpredictable concentrations of THC and other cannabinoids and hundreds of other molecules that have a pharmacological effect, so the final net effect cannot reliably be foreseen.
Acute effects while under the influence can sometimes include euphoria or anxiety. Although some assert that cannabidiol (CBD), another cannabinoid found in cannabis in varying amounts, may alleviate the adverse effects of THC that some users experience, little is known about CBD's effects on humans. Cannabinoid receptor antagonists have previously been tested as antidotes for cannabis intoxication with success, reducing or eliminating the physiological and psychological effects of intoxication. Some of these products are currently in development as cannabis antidotes. (Full article...)
Reefer Madness (originally made as Tell Your Children), a 1936-1939 American propagandaexploitation film revolving around the melodramatic events that ensue when high school students are lured by pushers to try marijuana — from a hit and run accident, to manslaughter, suicide, attempted rape, and descent into madness. Originally financed by a church group under the title Tell Your Children, the film was intended to be shown to parents as a morality tale attempting to teach them about the dangers of cannabis use. However, it was purchased by producer Dwain Esper, who re-cut the film for distribution on the exploitation film circuit through the 40s and 50s. Although finding a popular audience as a cult film, critics have panned it as one of the worst films ever made.

... that the passage of the A.B. 390 by California's Public Safety Committee marked the first time in United States history that a bill legalizing marijuana passed a legislative committee?
I have always loved marijuana. It has been a source of joy and comfort to me for many years. And I still think of it as a basic staple of life, along with beer and ice and grapefruits - and millions of Americans agree with me.
