Hospital inpatient alcohol and/or drug treatment for alcohol or drug addiction is very often necessary for people who have specific medical complications having to do with their addiction, as does sometimes occur with certain types of drug or alcohol detox or for persons whose physical or mental state has been compromised by their substance abuse. Hospital inpatient drug rehab in Waterloo for drug and alcohol issues is occasionally also necessary for men and women who have co-occurring mental health illness and will need intensive rehabilitation solutions which may not be available in another rehab. Persons who wish to receive a medication assisted drug detoxification, as is often the situation with individuals who are addicted to opiates such as heroin and prescription pain killers, may also decide to acquire such rehab in a Waterloo hospital inpatient drug and alcohol detoxification program.
