Residential long-term treatment is typically a drug rehabilitation center which offers treatment services longer than 30 days. At a residential long-term drug rehab facility the person will either be detoxed prior to their arrival at the center or be seen through detox and withdrawal on site. Drug rehab professionals will intensively work with the individual receiving rehab services to handle serious drug or alcohol addiction issues through counseling and various forms of therapy. This not only works to get individuals in Petersburg off of drugs but also helps clients remain off of drugs by handling the true reasons they became involved with drugs to begin with. Because this process may require weeks or months in treatment, a residential long-term treatment program which requires a stay of more than 30 days is one of the premier forms of drug and alcohol treatment available in Petersburg and one which provides the most substantial long term results when looking at success rates.
