Experimental Low-dose initiation |
Participants randomized to low-dose buprenorphine initiation will start low-dose buprenorphine-naloxone (bup-nx) according to an at-home, 8-day protocol (below). Participants in the low-dose buprenorphine initiation arm will be allowed to continue taking the full opioid agonist that they were taking at the time of enrollment until they reach a therapeutic dose of buprenorphine-naloxone. Day 1: 0.5 mg once; Day 2: 0.5 mg every 12 hours; Day 3: 1 mg every 12 hours; Day 4: 2 mg every 12 hours; Day 5: 3mg every 12 hours; Day 6: 4 mg every 12 hours; Day 7: 6 mg every 12 hours; Day 8: 8 mg every 12 hours |

Active Comparator Treatment as usual |
Participants randomized to treatment as usual will start buprenorphine-naloxone (bup-nx) following standard clinical guidelines for two-day, at-home initiation. |

Detailed Description
After being informed about the study and potential risks, all participants will be given written informed consent. Eligible participants will be randomized in a 1:1 ratio to an 8-day low-dose buprenorphine initiation protocol or treatment as usual, and conduct study visits at baseline and weeks 2 and 4. The investigators will also provide participants with mobile phones to collect real-time data on withdrawal, anxiety, craving and substance use through electronic Ecological Momentary Assessment (EMA) technology.
