There are quite a few different types of substance abuse rehab services in Chelsea which drug and alcohol addicted persons can avail themselves of. For example, there are drug and alcohol abuse rehabilitation programs which cater to somebody who has a short history of substance abuse and would potentially find luck at a short term alcohol and drug treatment program which will require the person to stay in rehabilitation for 4 weeks or less. For others there are more intensive and long term substance abuse rehabilitation centers which require a stay of 3 months or more, which is decided on the individual's background of alcohol and drug abuse and other variables such as co-occurring mental health issues. Drug and alcohol abuse treatment programs in Chelsea can be performed as an outpatient or as an inpatient, with inpatient alcohol and drug abuse rehab services providing substantially superior outcomes due to a higher quality of rehabilitation facility.
