Residential long-term treatment is a kind of alcohol and drug treatment program which provides treatment services for over 30 days. At a residential long-term drug rehab facility the person will either detox before arriving at the facility or be cared for during detox and withdrawal at the program itself. Drug and alcohol rehab professionals will work diligently with the individual in treatment to address serious drug or alcohol addiction problems by means of counseling and various other treatment methods. This not only helps get clients in Havana off of drugs but helps them remain drug free by addressing the actual reasons they became involved with drugs to begin with. Because the treatment process may require weeks or months in treatment, a residential long-term rehab program that demands a stay of more than 30 days is a superior choice in terms of drug rehab available in Havana and one which offers very significant long term outcomes in terms of success rates.
