There are quite a few different types of drug and alcohol abuse rehab services in Lancaster, California which alcohol and drug addicted clients can avail themselves of. As an example, there are alcohol and drug abuse treatment facilities which may be especially beneficial for somebody with a very brief history of substance abuse and would potentially find luck at a short term drug and alcohol rehab program which will require the person to remain in rehab for 30 days or less. Then there are far more extensive and long term substance abuse rehab centers which involve a stay of 3 months or even longer in some cases, which is decided on the individual's background of alcohol and drug abuse and other variables including co-occurring mental health problems. Substance abuse rehab services in Lancaster can be done on an outpatient basis or an inpatient basis, with inpatient substance abuse treatment programs offering considerably better success rates as a result of a higher quality of rehabilitation program.
