There are a number of different types of alcohol and drug abuse rehab services in Bristol which drug and alcohol addicted individuals can get help from. As an example, there are substance abuse rehab services in the Bristol area which may particularly help an individual with a brief background of drug and alcohol abuse and might be able to receive effective help at a short term alcohol and drug treatment center which will require the person to remain in rehabilitation for 4 weeks or less. Then there are far more intensive and long term substance abuse rehabilitation centers in Bristol which require a stay of 90 days or longer, depending on the individual's history of drug and alcohol abuse and other factors such as co-occurring mental health disorders. Substance abuse rehabilitation services can be completed on an outpatient basis or an inpatient basis, with inpatient drug and alcohol abuse treatment services providing substantially better success rates as a result of a higher quality of rehab center.
