The only chemical difference between THC Delta 8 and Delta 9 is where a particular double bond is found in the chain of carbon atoms. Delta 8 has a double bond on the eighth carbon atom of its molecular structure; Delta 9 has a double bond on the ninth carbon atom. Delta 9 binds to CB-1 receptors in the brain and can produce strong psychoactive effects, such as euphoria, relaxation, talkativeness and laughter, and, on the negative side, possibly anxiety and paranoia. THC Delta 8 can produce mild psychoactive effects, although they are much less impactful than THC Delta 9.Delta 8 is found in cannabis plant material in minimal quantities and harvesting enough plant raw material to take advantage of the low levels of Delta 8 would require too much time, effort and money.
THC Delta 9 is the cannabinoid that most marijuana users look for when they want to have a euphoric high and that's what most people refer to when they say “THC”. Delta THC interacts with CB receptors to produce multiple effects, such as anxiety relief, sedation, pain relief and more.
