The only difference between the two molecules is the location of a double bond between two carbons. The delta-8-THC craze began when an excess of CBD extracted from hemp grown in the USA. The US caused the price of CBD to plummet.
Delta 8
THC is a very special cannabinoid that could close the gap between compounds such as CBD and marijuana.It has its own effects that cannot be described as too similar to those of CBD or Delta 9 THC. Delta-8 THC and delta-9 THC come from the cannabis sativa plant, which naturally produces more than 100 cannabinoids or active components. However, while the plant contains significant amounts of THC delta-9, it contains very little THC delta-8, a minor cannabinoid. Because Delta 8 binds more weakly to the body's CB receptors, it generally has less potency and different effects on the body.
While marijuana and Delta 8 products may have mutually known properties in terms of their chemical structure, cannabinoids have completely different effects.
