Many people in need of drug and alcohol rehab in Simi Valley, California may may decide on an inpatient short-term alcohol and drug rehabilitation program which demands a stay of as little as 4 weeks. This may perhaps be a reasonable rehab choice for persons who have family or work obligations, and may require a brief but somewhat intensive time in rehabilitation. Moreover, people that have only a brief history of drug abuse may find this to be a suitable choice while a person with a more extensive and serious case of substance abuse may need a much more extensive time spent in rehabilitation. If an individual evidently has an extensive history of abuse and decides to choose a residential short-term rehab facility of as little as a month, it is often required that the person agree to regular follow-up care or move to an aftercare program where their progress can be overseen and so can receive the support needed in their rehabilitation process as much as feasible.
