Many people that need drug and alcohol treatment in Castaic may choose to take part in a residential short-term drug treatment program that only requires a stay of as little as 4 weeks. This may be an appropriate rehab option for people that have personal or job responsibilities, and may just require a short but intense course of rehabilitation. Furthermore, individuals who have a very short history of drug and alcohol abuse may find this to be a suitable choice whereas another person in Castaic, CA. who has a more significant and serious case of abuse and addiction might require a much more extensive course of rehabilitation. If someone does have a more severe history of drug and alcohol abuse and decides on a Castaic residential short-term rehabilitation option of 30 days or less, it is often suggested that the client adhere to standard follow-up care or take part in an aftercare program where their development can be monitored and so they can be supported in their rehab process as much as possible.
