HHC itself is a derivative of THC and therefore produces similar effects. Yes, HHC, when used in large quantities, can produce psychoactive effects.

It has only been studied more seriously and intensively for a few years by scientists who believe they can recreate an HHC that does not produce the psychoactive effects that THC does. The challenge is to find an economical way to separate the psychoactive effects while maintaining the active potency of the compound.

So research is moving in that direction.
