IQR inter-quartile range
Effect size (ES) of pairwise tests relative to alcohol indicated by: *ES > .1
^aTo clearly express degree of impairment, relative to the general population, for readers unfamiliar with the WHOQOL scale, WHOQOL scores are expressed as Australian general population z scores (i.e. difference, in Australian general population standard deviations, from Australian general population mean, based on Australian normative data reported by Hawthorne et al. 2006). To allow comparison with international data, scores on the commonly-used 0–100 scale are presented in parentheses, in italics, below z scores
^bDrugs combined includes cannabinoids, opioids, and stimulants, as well as benzodiazepines, GHB, and solvent/volatile inhalants
