Endocannabinoid System
Discovery of anandamide, the first endocannabinoid, leading to understanding of the ECS.
2016
Florida Amendment 2
Florida voters approved medical marijuana for qualifying patients with 71% support.
Modern Research Areas
Scientific research continues to uncover the therapeutic potential of cannabinoids. Here are key areas of study.
Studies show cannabinoids can modulate pain signals through the endocannabinoid system, offering relief for chronic pain conditions.
Extensive research available
FDA-approved Epidiolex (CBD) for certain types of epilepsy demonstrates the therapeutic potential of cannabinoids.
FDA-approved treatment exists
Research suggests cannabis may help regulate fear and anxiety responses, showing promise for PTSD treatment.
Ongoing clinical trials
Well-established use for chemotherapy-induced nausea and appetite stimulation in conditions like HIV/AIDS.
FDA-approved treatments exist
Preliminary research explores neuroprotective properties for conditions like Parkinson's and Alzheimer's.
Early-stage research
Both THC and CBD show anti-inflammatory properties that may benefit conditions like Crohn's disease and arthritis.
Growing body of evidence
What Research Has Shown
Modern cannabis research has accelerated since the discovery of the endocannabinoid system in the 1990s. Scientists have identified over 100 cannabinoids and numerous terpenes that may contribute to therapeutic effects.
The "entourage effect" theory suggests that cannabis compounds work better together than in isolation, which is why whole-plant medicine may be more effective for some patients than isolated cannabinoids.
While research is promising, it's important to note that cannabis remains a Schedule I substance federally, which has limited large-scale clinical trials in the United States.
"Cannabis is remarkably safe. Although not harmless, it is surely less toxic than most of the conventional medicines it could replace if it were legally available."— Lester Grinspoon, M.D., Harvard Medical School
Author of "Marihuana Reconsidered" (1971)
