Substance abuse can cause a strong chemical dependency in some, meaning their body does not know how to function without the drug or alcohol they were abusing and experiences withdrawal symptoms. Certain drugs and alcohol can cause serious and dangerous withdrawal symptoms that can even be fatal, which require a medical detox center. Medical detoxification treatment programs provide around-the-clock medical supervision and medication-assisted treatment to make sure the withdrawal process is safe and comfortable. Even when withdrawal symptoms are not dangerous, some people choose to enter a medical detox center in order to complete their drug or alcohol detox successfully and more comfortably.
