THC, CBD, CBG or CBN: these names refer to different cannabinoids. They are not interchangeable, and an observation about one molecule does not demonstrate the properties of all the others.
THC and CBD: two different profiles
THC is mainly associated with the intoxicating effects of cannabis. CBD does not produce these same effects, but that does not mean it has no side effects or interactions with medicines. The context of use and the composition of the product matter.
what the studies allow us to say
In the United States, a purified cannabidiol medicine, Epidiolex, has specific indications for seizures associated with three conditions: Lennox-Gastaut syndrome, Dravet syndrome and tuberous sclerosis complex. It is a medicine that has been evaluated and is prescribed in a medical setting. This US approval is neither a Swiss approval nor proof of efficacy for a CBD flower or oil sold commercially.
It is also important to distinguish between the cannabinoids studied: uses of dronabinol, a synthetic form of THC, for HIV-related loss of appetite are not evidence of CBD's efficacy. Nor do the data summarised by the NCCIH justify presenting CBD as an established treatment for glaucoma.
reading a promise methodically
To understand a study, look at what was actually tested: an isolated substance or a mixture, in humans or in the laboratory, and for which specific outcome. A possible biological mechanism is not yet a demonstrated clinical benefit.
This guide offers reading pointers. It does not suggest replacing any treatment with cannabis or CBD. Any question about an illness, ongoing treatment or an interaction is a matter for a healthcare professional.
