A Survey Study of Individuals Using Hexahydrocannabinol Cannabis Products: Use Patterns and Perceived Effects

Introduction: Across the cannabis market, multiple cannabinoids have seen rapid growth. Considering the differing effects between specific cannabinoids, it is critical to assess effects on an individual level. Hexahydrocannabinol (HHC) is one intoxicating cannabinoid that became more accessible due to regulatory shifts. The purpose of the current study was to provide descriptive data regarding HHC use patterns and perceived effects within a sample of participants who endorsed recent HHC use. Methods: One hundred nine individuals self-reported use of an HHC-cannabis product at least once within 6 months and completed an HHC use questionnaire via Prolific, an online crowdsourcing platform. Results: Findings suggest recent HHC users are using HHC relatively frequently (∼10 days during the past month) for various indications, including anxiety and pain. HHC was perceived to yield more good than bad effects, including relaxation and euphoria. Approximately 17% of the sample reported adverse effects, and ∼20% of those who stopped using HHC experienced some withdrawal symptoms. Few meaningful sex differences in subjective effect ratings were observed. Discussion: The current study provides critical preliminary data about consumer use patterns and perceived effects related to HHC. Such data are needed to further research on the potential therapeutic as well as detrimental effects of HHC and to better inform the consumers, health professionals, and regulators about a cannabinoid that is widely available the market.
