Detox clears the drugs or alcohol from your body and gets you through the worst of withdrawal. That is where a lot of people get it wrong. They treat the last day of detox like the finish line, when it is really the point where the actual work starts. Detox stabilizes your body. It does not change the habits, triggers, and thinking that led to use. What you do in the weeks right after is what keeps the detox from unraveling.
