Medicinal Cannabis Disclosure and Reasons for Non-disclosure in New Zealand

Aims: This study investigates demographic predictors of medicinal cannabis (MC) disclosures and non-disclosures in various contexts. Methods: 1,742 respondents from a large-scale, online survey in New Zealand, analysed through logistic regression models. Results: MC prescription holders and individuals with diagnoses were more likely to disclose MC use across all settings, while Asians were less likely. Māori were less likely to disclose for fear of police, whereas women perceived social stigma against women using cannabis. Pacific Peoples were more likely to disclose to employers. Respondents with prior drug testing experience or treating neurological or pain conditions were more likely to disclose in health settings. Respondents treating mental health were more likely to disclose to government services. Conclusion: MC disclosures are influenced by institutional contexts, perceived prejudices, and past experiences. Fear of judgement or consequences in workplaces and health settings are barriers to disclosure, highlighting the need for more supportive practices.
