Purpose: Appropriate preoperative screening techniques are needed to safely provide anesthesia to increasing numbers of cannabis using surgical patients.
Design: This was a quasi-experimental quality improvement project.
Methods: Preoperative identification of cannabis users by registered nurses (RNs) and certified registered nurse anesthetists (CRNAs) was compared to baseline identification rates. CRNAs' compliance with evidenced base guidelines was recorded. Perioperative medication requirements were recorded and compared between cannabis-users and noncannabis users.
Findings: Identification of cannabis users by CRNAs conducting preanesthetic assessments increased from 4.08% to 14.36% while RN identification improved from 11.22% to 13.81%. Compliance with identification guidelines was 69.2% among CRNAs. There were no differences in anesthetic requirements, complications, or postanesthesia care unit (PACU) length of stay between cannabis users and nonusers.
Conclusions: Preoperative identification of cannabis users allows for safer, more effective perioperative care by CRNAs, registered nurses, and surgical staff.

Rationale: Between periods of use, chronic cannabis consumers may display residual effects on selective cognitive functions, particularly memory and attention. Whether there are comparable deficits in real-world behaviors, such as driving, has not been thoroughly examined.
Objectives: The current study explored the association between driving simulator performance, cannabis use history, and demographic factors after ≥ 48 h of abstinence.
Objective: With the rising misuse of benzodiazepine (BZD) and associated overdose deaths, cannabis has been touted as a potential substitute with proposed benefit of better health outcomes. This two-year retrospective analysis examined whether cannabis use among BZD users was associated with changes in outcomes of (1) all-cause mortality, (2) hospitalizations, (3) emergency department (ED) visits, and (4) whether it demonstrated BZD-sparing effects on prescription quantity over time.
Methods: Using data from Yale New Haven Health System, we conducted a retrospective, longitudinal cohort study among BZD users.

Objective: Legal cannabis dispensary employees ("Budtenders") are a significant resource for cannabis users. Current research indicates that cannabis use may adversely impact mental health. Public perception, however, is often inconsistent with this evidence, leading to increased use and disproportionate harm towards individuals with mental health disorders.

Objective: Expectancies play a critical role in cannabis use behavior and are influenced by sociodemographic and intrapersonal factors. This study examined daily endorsement of positive and negative cannabis use expectancies using 28 days of ecological momentary assessments (EMAs) in relation to sociodemographics, mental health symptoms, and cannabis use disorder (CUD) among young adult cannabis-tobacco co-users.
Method: Ninety-seven young adult (ages 18-24) cannabis and tobacco co-users reported on anxiety symptoms, depressive symptoms, and possible CUD at baseline.

Objectives: Street sweeps, involving the state-enforced removal of makeshift residences and confiscation of personal belongings from people in public spaces, are a common tool employed by urban governments to address public health and safety concerns. Amidst the ongoing housing and toxic drug poisoning crises in Vancouver, Canada, we sought to characterize experiences of confiscation of personal belongings by city workers among unstably-housed people who use drugs people who use drugs.
Study Design: Cohort study.
