Some individuals in need of drug and alcohol rehab in Santa Ana may choose to take part in a residential short-term drug and alcohol rehabilitation facility which only calls for a stay of 30 days or less. This might be a reasonable rehab option for people that have familial or other extensive commitments, and may require a short but somewhat intensive time in rehab. Furthermore, individuals that have only a brief background of drug addiction may possibly find that this may be an appropriate choice while a potential clients struggling with a more significant and serious case of drug and alcohol abuse may be in need of an a much more significant and extensive course of rehabilitation. If someone evidently has a more serious history of drug and alcohol abuse and decides on a residential short-term rehabilitation program of as little as 4 weeks, it is often required that the client receive regular follow-up treatment or move to an aftercare program in which their sobriety can be supervised closely and so can receive the support needed in their rehab process as often as possible.
