Spontaneous and Catalytic Conversion of CBD to THC

[Extracted off Colorado Green Labs]

Cannabidiol (CBD) and tetrahydrocannabinol (THC) are nearly identical, but whereas THC is psychoactive, CBD is not. The two compounds differ only slightly in chemical structure – CBD is bicyclic (“two-ring”) and THC is tricyclic (“three-ring”). The carbon and oxygen molecules in the partial central ring of CBD will rearrange under various natural and artificial conditions to form THC. The rate of conversion is influenced by many factors, including length of storage time, exposure to light and air, ambient temperature, acidity, and the presence of protic solvents such as ethanol or methanol (alcohols).
