For example, there are drug and alcohol abuse treatment programs which may are geared towards someone who has a very brief case of alcohol and drug abuse and may benefit from a short term drug rehabilitation center which will require the person to remain in treatment for a month or less. For others there are much more extensive and long term alcohol and drug abuse treatment programs which involve a stay of 3 months or even longer in some cases, depending on the individual's background of alcohol and drug abuse and other things to be considered which may include co-occurring psychological problems. Drug and alcohol abuse rehabilitation services in Lisbon can be completed on an outpatient basis or an inpatient basis, with inpatient drug and alcohol abuse treatment programs resulting in significantly better success rates as a result of a higher quality of rehabilitation program.
