Yes it is...Delta-9 THC (Which is found in Marijuana) is not the only Tetrahydrocannabinol (THC) that naturally occurs within Cannabis. In fact, there are over 100 naturally occuring Cannabinoids found within the plant; the most common being Delta-9 THC and CBD.
Other forms of THC are pretty much identical molecularly and produce their own unique effects depending on what Cannabinoid you are using. With that being said, every BODY is different so always START LOW - GO SLOW!
So yes...it is a "REAL THC".
