There are quite a few unique types of drug and alcohol abuse rehabilitation programs in Callao which addicted persons can avail themselves of. As an example, there are alcohol and drug abuse treatment facilities which cater to an individual who has a short background of substance abuse and would potentially find luck at a short term drug and alcohol rehabilitation program which will call for the individual to remain in rehab for 30 days or less. For others there are far more extensive and long term substance abuse rehabilitation services which require a stay of 3 months or even longer in some cases, which is decided on the individual's particular case of drug and alcohol abuse and other factors such as co-occurring psychological problems. Drug and alcohol abuse rehab programs in Callao can be carried out as an outpatient or as an inpatient, with inpatient alcohol and drug abuse rehab programs providing significantly better success rates because of a greater quality of rehabilitation facility.
