There are a number of unique types of alcohol and drug abuse rehab facilities in Chattanooga which drug and alcohol addicted people can benefit from. For example, there are alcohol and drug abuse rehabilitation programs in the Chattanooga area which work specifically with an individual with a short background of alcohol and drug abuse and may possibly be able to receive effective help at a short term alcohol and drug rehabilitation center which will require the person to remain in rehabilitation for 4 weeks or less. Then there are far more intensive and long term alcohol and drug abuse rehabilitation facilities in Chattanooga which demand a stay of 90 days or more, based off of the client's history of alcohol and drug abuse and other factors which may include co-occurring mental health disorders. Substance abuse rehabilitation programs can be done on an outpatient basis or an inpatient basis, with inpatient substance abuse rehab services offering substantially superior success rates because of a higher quality of rehab facility.
