Kendall’s tau estimates of between-drug LOTAD associations

Cannabis Alcohol Opiates
Alcohol .095 (114)
Opiates -.072 (55) -.137 (66)
Cocaine .065 (126) .048 (213) -.022 (113)

Notes: Parenthetical values contain the number of participants available for reanalysis. Sample sizes were considerably smaller than for other analyses because participants had to have met criteria for both abuse and dependence pertaining to the use of two or more drugs. None of the Kendall's taus were significant (p> .05).
