Recent anecdotal reports of illegal drug supplies in many small towns in NZ suggest that cannabis is becoming harder to obtain, whereas methamphetamine is becoming ever easier to obtain. Outcomes are reported from an anonymous online survey of alcohol and drug use in NZ, promoted via a broadly targeted Facebook™ campaign conducted from November 2017 to February 2018 and targeted at people aged ≥16 years. A total of 6,311 surveys were completed and returned. Across NZ, respondents reported methamphetamine as more available than cannabis. Methamphetamine was easier to obtain in towns and rural areas than in cities. In logistic regression analysis, statistically significant predictors of reporting high availability of methamphetamine were living in a town/rural area (OR 1.38), purchasing from a gang member (OR 1.88), daily methamphetamine use (OR 2.41), Māori ethnicity (OR 1.36) and reporting low availability of cannabis (OR 1.89). Low availability of cannabis failed to predict for high availability of ecstasy or LSD. Living in a town/ rural area did not predict for high availability of cannabis, LSD or ecstasy. Purchasing from a gang member predicted for high availability of cannabis (OR 1.80) and LSD (OR 4.61).
