Many people looking into drug treatment in California may choose to take part in a residential short-term alcohol and drug rehabilitation center that requires a stay of as little as 4 weeks. This might be an acceptable treatment choice for people who have personal or job commitments, and only require a brief but intense length of time in rehab. Furthermore, people with a very short history of alcohol and drug abuse might find this to be a preferable method of treatment whereas someone in California with a more significant and severe case of substance abuse might require a more extensive course of treatment. If someone is known to have an extensive background of drug and alcohol abuse and chooses a California residential short-term rehabilitation facility of 30 days or less, it is often recommended that they receive standard follow-up care or take part in an aftercare plan where their development can be monitored and so they can be supported in their rehab process in every way feasible.
