The IDMS interviews three groups of frequent illegal drug users (i.e. IDU, methamphetamine users and ecstasy users) from the three main cities of New Zealand using purposive sampling and \u2018snowballing\u2019.<\/jats:p><jats:p><jats:bold>Results.<\/jats:bold> Pharmaceutical morphine rather than heroin was the principal opioid used by the IDU. Few of the IDU or frequent methamphetamine users had prescriptions to use morphine. A lower proportion of the IDU had a prescription to use morphine in 2009 compared to 2008. The injection of methadone by IDU and methamphetamine users was common. A higher proportion of the IDU had injected methadone in 2009 compared to previous years. A higher proportion of the IDU had used oxycodone in 2009 compared to 2008 and prescription use of oxycodone by IDU was very low. All three groups of frequent drug users were involved in the extra\u2010medical use of methylphenidate and benzodiazepines.<\/jats:p><jats:p><jats:bold>Discussion and conclusion.<\/jats:bold> Extra\u2010medical use of pharmaceuticals occurred among all three groups of frequent illegal drug users to varying degrees. Differences between the three groups in the level and type of extra\u2010medical pharmaceutical drug use suggest that different control strategies may be effective for each group.
