Abstract
Although much is known about Δ9-tetrahydrocannabinol and its inactive open ring isomer, cannabidiol, far less is known about the effects, metabolism, and pharmacodynamics of Δ9-tetrahydrocannabinol's double-bond isomer, Δ8-tetrahydrocannabinol. With the passage of the so-called United States "Farm Bill," which was made law in order to allow legal hemp cultivation in the United States, more needs to be known about the effects of Δ8-tetrahydrocannabinol, a double-bond isomer of Δ9-tetrahydrocannabinol, and cannabidiol (CBD), which is an open-ring isomer of Δ8-tetrahydrocannabinol. It is the aim of the review to summarize current knowledge of Δ8-tetrahydrocannabinol and CBD, including the pharmacodynamics and pharmacokinetics of CBD. Also, plant genetics, the effect of cannabinoids on the current topic of viral entry into mammalian cells, and the current practice of vaping, dabbing, and dripping are covered.
