This study will examine the feasibility, appropriateness, and acceptability of a bundle of smartphone-based tools for lowering overdose risk. 40 participants will be enrolled and can expect to be on study for up to 9 months.

As a pilot study, this study is not designed to rigorously evaluate the effect of the intervention (i.e., health-related biomedical or behavioral outcome) on participants. Rather, the sample size will allow determination of feasibility, acceptability, appropriateness, and secondarily, will allow quantification of preliminary effect size to aid in future trial planning. After enrolling in the study, participants will receive a mobile phone with an unlimited data plan. After receiving the phone, participants will receive a brief orientation to a bundle of phone and internet-based overdose prevention tools. This includes overdose crisis hotlines, mail-order overdose prevention supplies, and a mobile health app that has been adapted for people who use drugs to support self-determined motivation for reaching goals through educational content, social engagement, and peer-to-peer support. Each month for 6 months, participants will also complete a 20-30 minute survey evaluating the primary and secondary outcomes (described below) and use of each phone and internet-based tool that is part of the enhanced harm reduction bundle. 25 participants will also be invited to complete a 45-60 minute semi-structured in-depth interview about their experience participating in the study and use of the phone- and internet-based tools. Primary analyses will seek to describe the feasibility, acceptability, and appropriateness of the overdose prevention service model. Secondarily, changes in overdose risk behaviors and experiences over the 6-month study period relative to baseline will be analyzed.

Primary Objective: to evaluate feasibility, appropriateness, and acceptability of an enhanced harm reduction service model incorporating internet and/or mobile health tools to reduce overdose risk for people who use opioid and/or stimulant drugs.

Secondary Objective: to understand overdose risk behaviors before and after the intervention.
