Legal party pill use in New Zealand: Prevalence of use, availability, health harms and ‘gateway effects’ of benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP)

The principal aims of the 2006 National Household Survey of Legal Party Pill Use were to provide national population statistics on the prevalence and patterns of legal party pill use in New Zealand, and to provide data on the harms and problems related to the use of legal party pills in New Zealand. The survey consisted of a random national household sample of 2,010 people aged 13-45 years old collected using the Centre for Social and Health Outcomes Research and Evaluation (SHORE) and Whariki’s in-house computer assisted telephone interviewing (CATI) system.
