Key findings

  • Nine hundred and nighty-nine IDRS participants were interviewed in SA from 2007-2016. Demographics across the years have remained relatively stable.
  • Over the last decade, recent use of ‘any’ form of methamphetamine has remained high and fairly consistent.
  • A change was observed from 2007 to 2016 for crystal methamphetamine users, with an increase in the proportion of participants reporting recent use of crystal methamphetamine, from 41% in 2007 to 75% in 2016.
  • Binary logistic regression analysis indicated that in 2016, participants were significantly less likely to have recently used powder or base, when compared to crystal methamphetamine (p<0.01).
  • From 2007 to 2016 a significant increase occurred in the proportion of participants reporting crystal methamphetamine as the form most used, from 29% in 2007 to 86% in 2016 (p<0.01).
  • Multinomial regression analysis indicated that in 2014, 2015 and 2016, participants were significantly less likely to report powder as the form most used, when compared to crystal methamphetamine (p<0.01).
  • No significant difference was found between 2010 and 2016 in relation to stimulant dependence, although half of respondents in 2016 had scores indicative of stimulant dependence.
