CBD isolate is the purest form of CBD available, usually comprising over 99% cannabidiol. It comes in a crystalline powder or solid form, which is odourless and tasteless. The extraction process involves isolating CBD from the cannabis plant and removing all other compounds, including THC (tetrahydrocannabinol), the psychoactive component of cannabis. This makes CBD isolate an ideal choice for those who want to avoid any THC content altogether.
