Driving after cannabis use is associated with a number of risks. Examination of driving after cannabis use among young adults is particularly important, as young adults have the highest rates of cannabis use and among the highest rates of traffic crashes. The current study examines rates and correlates of driving after cannabis use among young adults (aged 18-25) who reported past month cannabis use. Participants were from Michigan and recruited through paid Facebook and Instagram advertisements between February and March 2018 (=461). Nearly a third (31.9%) of the sample reported driving after cannabis use in the past month. Young adults who were employed (aOR=1.872, =0.045), had medical cannabis cards (aOR=2.877, <0.001), endorsed coping reasons for use (aOR=2.992, =0.007), and endorsed social/recreational reasons for use (aOR=1.861, =0.034) had greater odds of driving after cannabis use. Students had lower odds of driving after use (aOR=0.573, =0.011). Employment and having a medical cannabis card may be important risk markers for identifying individuals more likely to drive after use of cannabis. Prevention efforts could provide psychoeducation at dispensaries to individuals with medical cannabis cards about the risks of driving after use. Coping motives for cannabis use may also be useful in identifying young adults at the greatest risk of driving after use of cannabis.

Recreational cannabis use has increased notably in the United States in the past decade, with a recent surge in oral consumption. This trend has raised concerns about driving under the influence. Current cannabis-impaired driving laws lack standardization, with some states implementing blood Δ9-tetrahydrocannabinol (THC) per se limits (1, 2, and 5 ng/mL).

The presentation of comorbid post-traumatic stress disorder (PTSD) and substance use disorder (SUD) differs by substance type. The current study applied network analysis to explore the relationships between diagnostic symptom clusters by examining the strength and direction of unique associations between PTSD and SUD. Network analyses were estimated using a sample of 422 veterans diagnosed with co-occurring PTSD/SUD initiating psychotherapy for PTSD while receiving concurrent outpatient SUD treatment as part of a randomized clinical trial.

Background: People exposed to fentanyl may report that the dose of methadone in the commonly accepted therapeutic range feels too low. We examined self-reported methadone dose adequacy.
Methods: We conducted a retrospective cohort study of individuals prescribed methadone at a dose of at least 60mg daily using data from three community-recruited prospective cohort studies of people who use drugs in Vancouver, Canada from December 2016 through March 2020.
