Determinants of high availability of methamphetamine, cannabis, LSD and ecstasy in New Zealand Are drug dealers promoting methamphetamine rather than cannabis
Small towns in New Zealand have reported high availability of methamphetamine, and conversely a shortage of cannabis. Stakeholders have suggested drug dealers are purposely promoting methamphetamine rather than cannabis. (1) To compare the availability of methamphetamine and cannabis in different size communities (2) Identify determinants of the high availability of methamphetamine, including low availability of cannabis. An online drug survey was promoted via a broadly targeted Facebook™ campaign. Participants were asked if they lived in a city, small town or rural area, their drug use patterns, and local drug market characteristics, including current availability. A total of 6311 people completed the survey. Logistic regression models were constructed to identify independent predictors of reporting high availability of methamphetamine, cannabis, ecstasy and LSD respectively, with low availability of cannabis included as a predictor in the non-cannabis markets. Methamphetamine was reported to be more available than cannabis in all regions. Methamphetamine was more available in townsrural areas than in cities. Significant predictors of high availability of methamphetamine were living in a townrural area (OR 1.38), purchasing from a gang member (OR 1.88), daily methamphetamine use (OR 2.41), Maori ethnicity (OR 1.36) and reporting low availability of cannabis (OR 1.89). Low availability of cannabis was not a predictor of high availability of ecstasy or LSD. Living in a townrural area was not a predictor of high availability of cannabis, LSD or ecstasy. Purchasing from a gang member was a predictor of high availability of cannabis (OR 1.80) and LSD (OR 4.61). Further research is required to identify what causal relationships, if any, there are between the statistical associations of high methamphetamine availability, living in a small town, purchasing from a gang, and low cannabis availability. It may be the case that small towns offer an environment where a gang can control the local drugs market.
