There could be serious transformations in body and brain chemistry due to substance abuse. Detox centers start treatment by removing toxins and their byproducts from the body of the addict. At these detox centers, medical supervision and help are provided during the first few days or hours of sobriety. This is done to make sure that the recovery process is helping you or your loved one in the best possible way. Most detox centers follow a similar treatment methodology under a safe and professional environment. It may further include therapy sessions and counseling.
