Some individuals take part in a residential short-term alcohol and drug treatment program which calls for a stay of 30 days or less. This rehabilitation option may be appropriate for individuals in California who have personal or work responsibilities, and only require a brief but intensive course of rehabilitation. Individuals in California with only a short background of alcohol and drug misuse may also discover this to be a suitable option. Somebody in California who has a more extensive and significant case of abuse and drug or alcohol addiction may require a much more substantial program of rehab. If somebody does have an a more extensive history of abuse and makes the decision to choose a residential short-term treatment option of 30 days or less, it is typically encouraged that they obtain regular follow-up treatment or take advantage of an aftercare program where their progress can be looked after in their rehab process in every way feasible.
