- Patients with cocaine and cannabis use disorder have different impulsivity profiles.
Why this matters
- Substance use disorders have previously been associated with increased impulsivity.
- Being National Institute on Drug Abuse (NIDA) risk score-positive for cannabis or cocaine use disorder was significantly associated with Barratt Impulsiveness Scale (BIS)-11 score.
- NIDA risk score-positivity for cannabis use disorder was significantly associated with BIS-attentional and BIS-nonplanning subscores (P=.034 and .002, respectively), but not with BIS-motor subscore (P=.283).
- NIDA risk score-positivity for cocaine use disorder was significantly associated with BIS-nonplanning subscore (P=.001), but not with BIS-motor subscore or BIS-attentional subscore (P=.293 and .067, respectively).
- Researchers assessed impulsivity and substance use among psychiatric inpatients (n=184).
- Impulsivity was assessed by administering the BIS-11.
- Cannabis use and cocaine use were assessed using NIDA risk scores.

- The study was conducted in a single center and relies on self-report data for impulsivity, and may not contain data representing the least functional patients.
