Sublocade Long-term Outcomes Study is a research project looking at how well people do when they use a medication called **Sublocade** over a long time. **Sublocade** is a medicine used to help people with **Opioid Use Disorder (OUD)**, which means they have been using drugs called opioids in a harmful way.

It will take place in many locations and involve people who either currently have or have had OUD. The study will go on for up to 4 years. Participants need to be at least 18 years old and must have started using **Sublocade** in the last 3 months or have finished a past **Sublocade** study. During the study, researchers will check on participants' physical, mental, social, and financial well-being.
