Partial Hospitalization, sometimes called "PHP" or Day Treatment, is a kind of alcohol and drug treatment facility which works to treat drug addiction problems and mental health disorders which might be co-occurring. In a PHP program, the treatment client in rehab partakes in a number of rehabilitation activities and techniques in the day and then returns home in the evening. This is done anywhere from five to seven days a week, depending on the significance of the drug or alcohol problem. Partial Hospitalization can be helpful for drug addicted persons in San Anselmo, California who are unable to pay for long-term inpatient treatment, or who are not able to be away from their home and work for extensive lengths of time. While in Day Treatment, treatment clients take part in standard treatment services for addiction problems while at the same time addressing psychological issues which may deter them from staying abstinent after rehabilitation is done.
