Language was included as a covariate; the Wald statistic follows a χ2 distribution; d = Cohen's d. Hallucinogens include psilocybin (“magic mushrooms”), LSD, and PCP; ADHD medication includes methylphenidate and amphetamine sulphate; and sedatives include tranquilisers and hypnotics. Heroin was excluded due to small sample sizes. See Figure 1 for the structure of the statistical analyses. ADHD, attention deficit/hyperactivity disorder; ADHD S–, ADHD screened negative group (ASRS score <14); ADHD S+, ADHD screened positive group (ASRS score ≥14); ASRS, Adult ADHD Self-Report Scale; CD, conduct disorder; CI, confidence interval; OR, odds ratio; SS, sensation seeking; SU, substance use; AUD, alcohol use disorder; CUD, cannabis use disorder.
