Delta 9 is THC, same as the plant. Probably better than any synthetic cannabinoids.
Discussion
It is good, i think it is slightly different in how the decarboxolate it though. The guy at the store gave me an overview.
The only think i don't like about it is it makes you super sleepy and if you take too much you sometimes hear and see random stuff.
All cannabinoids distort perception at high dosages, but it's still mild compared to ketamine or tryptamines like psilocybin.
