The length of an alcohol detox depends on several factors, including the severity of the person’s alcohol use disorder and their overall health status. In general, an alcohol detox can last anywhere from a few days to a few weeks. However, in severe cases, it can take several weeks or even months to fully detox from alcohol. The detox process is usually followed by ongoing addiction treatment and support to help the person maintain sobriety. It’s important to seek professional medical and psychological assistance during the detox process to ensure that it’s done safely and effectively.
