Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner. In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity. A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC. Little is known about potential drug interactions, but CBD-mediates a decrease in clobazam metabolism.
Cannabidiol has low affinity for the cannabinoid CB1 and CB2 receptors, although it can act as an antagonist of CB1/CB2 agonists despite this low affinity. Cannabidiol may be an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain. It also may act as an inverse agonist of GPR3, GPR6, and GPR12. CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist. It is an allosteric modulator of the μ- and δ-opioid receptors as well. The pharmacological effects of CBD may involve PPARγ agonism and intracellular calcium release.
In addition, some cannabinoids interact synergistically, producing unique effects that are not found when using them individually. For example, CBD inhibits THC’s psychotropic effects when the two are taken together. However, CBD does this (and produces many other effects) without directly interacting with the cannabinoid receptors. At first, scientists thought there was a third type of CB receptor just for Cannabidiol, but the answer was far more interesting and revealing.
A disclaimer here: I am not a professional in this field. The symptoms I describe below and attribute to either to under or over dose of nicotine are information I have assembled by reading web sites and published studies; my advice is based only on that. I can not promise that they are absolute indications. Above all in your process of switching to vaping, listen to your body. If you can work out what it is telling you then that’s the best advice of all. vaping
