Survey of HHC users found they used it about 10 days per month, mostly for anxiety and pain, with some reporting withdrawal

HHC users reported using approximately 10 days in the past month. Common reasons included anxiety and pain management. Users perceived more positive effects (relaxation, euphoria) than negative ones. About 17% reported adverse effects, and approximately 20% of those who stopped using HHC experienced some withdrawal symptoms. Few sex differences were observed.

HHC is a semi-synthetic cannabinoid that became widely available through regulatory gaps in the hemp market. This is among the first studies providing systematic data on who uses HHC, how often, and what they experience, filling a major gap as regulators consider how to handle novel cannabinoids.

As novel cannabinoids proliferate in the consumer market ahead of safety research, user surveys like this provide initial safety signals. The withdrawal finding is notable because it suggests HHC may produce dependence similar to THC despite limited pharmacological research.
