What the trial is, and whether it could suit you

Cannabis, in addition to its psychotropic properties, could have anti-inflammatory and immunomodulatory effects. Phytocannabinoids (pCBs) are a group of molecules naturally secreted by the cannabis plant. The major pCBs are cannabidiol (CBD) and Δ9-tetrahydrocannabinol Δ9 (THC). Only THC has psychotropic effects, which CBD does not have. Alongside these two main components, there is a wide variety of other molecules, such as other pCBs and terpenes which could increase the effects on immune system through synergistic interactions between these different compounds ("entourage effect").In vivo, pCBs essentially interfere with the endocannabinoid system, acting on many ubiquitous receptors, present on a significant number of different cell types. Numerous published studies show that pCBs have immunomodulatory and anti-inflammatory properties by acting on several of these receptors, whether
