CBD-HQ is the abbreviation of Cannabidiol-Hydroxy Quinone and is basically the oxidised version of CBD, which occurs in nature when cannabis or hemp is left open to elements like sun and air. This process can take up to 20 years to occur naturally and then only a small percentage of CBD will turn into CBD-HQ, meaning up until the last few years CBD-HQ in its purist form cost 1000 times more than gold.
