Is this trial a fit for you?
✓Likely a good fit
Adults 18 years and older who use illicit drugs or non-oral opioid use in the past 30 days, report recent use at least twice in the past week, and express unmet needs for harm-reduction services.
✕Probably not a fit
Individuals without recent drug use or those not seeking harm-reduction services may not benefit from the toolkit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a feasibility-focused pilot study enrolling 40 adults to test a mobile health toolkit for overdose prevention, including crisis hotlines, mailed supplies, and an adapted app for motivation and peer support. Participants receive a smartphone and unlimited data, plus monthly surveys and optional in-depth interviews to gauge feasibility, acceptability, and appropriateness of the intervention. The study will quantify preliminary effect sizes to inform future trials, without making strong claims about biomedical or behavioral outcomes. Data will be collected over up to 9 months to understand how the tools are used and perceived by people who use drugs and related populations.
Why it matters
Potential benefit: If successful, participants may experience greater access to overdose prevention resources and support, potentially reducing overdose risk.
How similar studies have gone: Prior small-pilot efforts with mobile harm-reduction tools have shown promise in feasibility and acceptability, but robust effectiveness data are limited.
