There are quite a few various types of substance abuse rehab services in Cambridge which drug and alcohol addicted persons can take advantage of. For example, there are alcohol and drug abuse rehabilitation facilities which may are geared towards a treatment client who has a very brief history of drug and alcohol abuse and would potentially find luck at a short term alcohol and drug rehabilitation program which will call for the treatment client to stay in treatment for a month or less. For others there are far more intensive and long term alcohol and drug abuse treatment services which require a stay of 3 months or even longer in some cases, which is decided on the individual's history of drug and alcohol abuse and other factors such as co-occurring psychological disorders. Alcohol and drug abuse treatment services in Cambridge can be performed on an outpatient basis or an inpatient basis, with inpatient alcohol and drug abuse rehabilitation services offering substantially superior success rates due to a greater quality of rehabilitation setting.
