How CBD Works

Cannabidiol (CBD), a non-psychoactive component of the cannabis plant, has generated significant interest among scientists and physicians in recent years—but how CBD exerts its therapeutic impact on a molecular level is still being sorted out.

Terpenes and the "Entourage Effect"

Cannabis terpenes interact synergistically to create what scientists refer to as an “entourage effect” that magnifies the therapeutic benefits of the plant’s individual components—so that the medicinal impact of the whole plant is greater than the sum of its parts.

The Endocannabinoid System

Research on marijuana’s effects led directly to the discovery of a hitherto unknown biochemical communication system in the human body, the endocannabinoid system, which plays a crucial role in regulating our physiology, mood, and everyday experience.

Is "Pure" CBD Better?

Scientific studies have established that synthetic, single-molecule CBD has a narrow therapeutic window and requires high doses for efficacy as compared to whole-plant, cannabis-derived CBD.

Is CBD Toxic to the Liver?

The huge popularity of cannabidiol has helped to destigmatize the plant and restore its reputation as an important medicinal herb. But bogus science and inept reporting continue to distort how we understand the benefits and risks of CBD and cannabis.
Abstract background

CBD & the Psychedelic Receptor

Reported initially in 2005, the discovery that CBD interacts directly with these (and other) 5-HT receptors hints at a broader relationship between the endocannabinoid and serotonergic systems that scientists are still uncovering.

Sequencing the Cannabis Genome

The Massachusetts-based company Medicinal Genomics has sequenced the entire genome of Cannabis sativa L. The announcement received much attention. But how will it impact research and public health?
