Many people who will need alcohol and drug treatment in San Anselmo, California may choose to take part in a residential short-term drug rehabilitation facility which only requires a stay of as little as 4 weeks. This may be a reasonable rehab possibility for clients that have personal or work commitments, and simply need a brief but intensive course of treatment. Furthermore, persons with only a short background of drug and alcohol addiction may find that this may be a valid option while someone struggling with a more significant and severe history of drug and alcohol abuse may need a more extensive time in rehab. If someone evidently has a more serious background of drug and alcohol abuse and chooses a residential short-term treatment program of 30 days or less, it is frequently required that the individual agree to typical follow-up treatment or move to an aftercare facility where their overall wellness can be monitored and so can receive the support needed in their rehab process as much as feasible.
