What is Delta 9?

Delta-9 refers to delta-9-tetrahydrocannabinol, commonly known as THC.

Not a Delta 9 Compound-but it looks cool.

THC is the primary psychoactive compound found in cannabis that is responsible for the "high" or intoxicating effects when consumed. Delta-9 specifically refers to the specific position of a double bond in the THC molecule. It is the most well-known and studied cannabinoid in cannabis and is what gives marijuana its euphoric and mind-altering properties.

When people talk about THC in cannabis, they are usually referring to delta-9-THC.
