There are numerous various types of alcohol and drug abuse rehabilitation programs in May which addicted persons can be helped from. As an example, there are alcohol and drug abuse rehab centers which may be especially beneficial for someone with a very brief case of substance abuse and may find luck at a short term alcohol and drug rehabilitation program which will call for the individual to remain in treatment for 4 weeks or less. For others there are more intensive and long term alcohol and drug abuse rehabilitation facilities which involve a stay of 3 months or even longer in some cases, depending on the individual's particular case of substance abuse and other factors which may include co-occurring psychological issues. Drug and alcohol abuse treatment programs in May can be done as an outpatient or as an inpatient, with inpatient substance abuse rehabilitation services offering significantly better outcomes as a result of a greater quality of rehab program.
