“The number of patients reporting the use of cannabis for medical purposes, whether through state-regulated medical marijuana programs or through over-the-counter hemp extracts, continues to grow. The growth in medicinal use of cannabis has in many ways surpassed the scientific data on the benefits and hazards of cannabis, and the scientific community has largely been left playing catch-up. Since 1996, when California became the first jurisdiction to legalize medical cannabis, the number of states following suit has grown and is currently at 37, while nearly 50 countries have legalized medical cannabis (and even more have decriminalized the plant) including Canada, Austria, Uruguay, Australia, South Korea, and Lesotho.
Cannabis sp. produces a number of phytochemicals with potential medical benefits including terpenes, flavonoids, and a unique class of molecules called cannabinoids, of which Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are the two most studied. Amazingly, the plant produces over 100 different cannabinoids with different potential therapeutic targets and activities, and these remain understudied.
The therapeutic benefits of cannabinoids are due, in large part, to the endocannabinoid system that exists in the human body, in addition to the ability of cannabinoids to interact and signal through a large number of disparate receptor molecules.”
“Cannabis is a complicated plant that produces over 100 cannabinoids in addition to terpenes and flavonoids. Adding to the complexity of trying to address the mechanism of action for cannabis is the fact that the cannabinoids that have been studied have been reported to exhibit activity at a number of different receptors.
This makes cannabinoids (and cannabis) a promiscuous drug. While typically viewed as a negative, promiscuous drugs do offer some advantages, most notably the ability to target different pathways of a disease with one medication.
The field of medical cannabis is growing rapidly, and as patients continue to use this plant to treat their conditions, there will remain a growing need for the scientific and medical communities to better understand how cannabis can impact the body.”
