The time it takes for the human body to detox from alcohol and/or drugs varies from one person to the next. It will also depend on the sort of drug and how often it is taken. The physical withdrawal symptoms of detox can last anywhere from a few days to a few weeks. The most severe symptoms usually last only a few days (such as nausea and vomiting). Many people will suffer cravings for their drug or alcohol for several weeks beyond the initial few days of detox. Our professional medical staff at CRC assist each client in coping throughout this time by providing a variety of therapies.
