Thirty-day rehab programs can be effective for some people, but it depends on various factors such as the severity of the addiction, the individual’s motivation to change, and the level of support they have. Short-term programs can be useful in providing an initial detoxification and stabilization period, as well as introducing the person to the basic principles of addiction treatment. However, many people require longer-term treatment and support to address the underlying issues and sustain long-term recovery. It is essential to consult with a qualified addiction professional to determine the most appropriate treatment program for an individual’s needs.
