DOC drug of concern, SDOC secondary drug of concern, SDS severity of dependence scale, IQR inter-quartile range
Effect size (ES) of pairwise tests relative to alcohol indicated by: *ES > .1, **ES > .3
For analyses of specific substances as SDOC, participants with the substance as PDOC were excluded
^aDrugs combined includes cannabinoids, opioids, and stimulants, as well as benzodiazepines, GHB, and solvent/volatile inhalants
^bSmoked tobacco on the majority (i.e. 16–30) of the past 30 days
