Creating better health outcomes for people who use substances through studying and supporting pharmacologic, behavioral, and system interventions addressing substance use and related health outcomes.
Fentanyl-related cardiac arrests had less bystander CPR, fewer shockable rhythms, and more severe brain injury on EEG, but good neurological outcomes were similar to other causes. This highlights unique challenges in fentanyl-linked cardiac arrest cases.

This study found that opioid overdose survivors who perceive themselves at higher risk are over twice as likely to overdose again within four months. Assessing risk perception can help target and improve overdose prevention efforts.

Among opioid OD survivors, less than half of OD's involved EMS, about one-third led to emergency visits, & few resulted in hospitalization. Most overdoses had naloxone given by bystanders. Relying only on healthcare data underestimates non-fatal overdose rates.

The ADAPT-2 trial found, higher craving and impulsivity predicted worse outcomes in methamphetamine treatment with naltrexone and bupropion. Targeting these factors may improve treatment response.

Patients with chronic pain who continued receiving opioids were more likely to get recommended preventive care. Those who lost access received less. Opioid stewardship should include support for ongoing healthcare engagement.

Background In response to increasing opioid overdose, US providers reduced opioid prescribing, resulting in several unintended consequences. Methods We assessed the impact of opioid receipt on quality...

New CSUH paper published in Drug and Alcohol Dependence:

Many stimulant-only drug deaths are witnessed and often linked to heart issues, unlike opioid cases. Analyzing medical examiner records helps uncover patterns and improve prevention efforts.
Thematic analysis of medical examiner narratives to understand the socio-spatial context, recency of drug use, and likely mechanism of stimulant toxicity deaths
Drug toxicity as a cause of death is challenging to establish and may be based on limited evidence, especially in deaths attributed to stimulants. We …

Study of 600 opioid patients: Stimulant use didn’t boost emergencies or deaths, yet those positive were nearly three times as likely to have treatment stopped. Researchers urge discussing substance use rather than automatically halting opioids.
