Cannabinoids are compounds derived from or based on chemicals found in the Cannabis sativa plant. These compounds have considerable potential for the treatment of a wide variety of symptoms and diseases, but the perceived association of cannabinoids with marijuana gives rise to a lot of misconceptions in this area.
HISTORY OF MEDICAL CANNABIS IN CANADA
Cannabis has been utilized for various reasons throughout history. The Cannabis sativa plant originated in the temperate climates of Asia, and has been spread around the world and cultivated for use in making rope. Between 1937 and 1971 a series of laws and conventions led to the ban of cannabis in North America and much of Europe.
Research into the psychoactive ingredients in cannabis led to the isolation of delta-9-tetrahydrocannabinol (THC), the main psychoactive ingredient, followed by continuing research into the properties of cannabinoids – compounds derived from or based on chemicals specific to the Cannabis sativa plant.
Health Canada released a research plan for the medical use of marijuana in 1999. In 2001, The Marijuana Medical Access Regulations (MMAR) enabled Canadians with serious diseases access to medicinal marijuana, which evolved into the Marihuana for Medical Purposes Regulations (MMPR) in 2013 and most recently replaced with the Access to Cannabis for Medical Purposes Regulations (ACMPR) in 2016.
Therapeutic effects of cannabinoids are being continuously researched in Canada and internationally in order to gain a deeper understanding of their effects on the human body and uses in health and disease.
