Delta-8-THC, with more limited psychoactive effects relative to its Delta-9-THC cousin, is only found naturally in trace quantities in cannabis, but can easily be created by the semi-synthetic isomerization from the readily available and inexpensive CBD, extracted from compliant hemp biomass. However, the synthetic processes used for these conversions can be unpredictable, resulting in consumer products containing unintended side products, contaminants and isomers of THC.
