We need to set people up for success. Recovering from addiction is not just going to treatment. It's going to detox, waiting to get into treatment, going to treatment and then the housing aftercare that follows.
If you've been in active addiction for however long, it's many times longer to unlearn the behaviour. We need to put more supports in place, not just for addiction but for mental health. We need to support people in ending the cycle of homelessness.
