Many people who will need drug treatment in Philadelphia may opt for a residential short-term drug and alcohol rehab center that only calls for a stay of as little as 4 weeks. This may be an appropriate rehab possibility for individuals who have personal or office obligations, and may require a brief but intensive course of rehabilitation. In addition, people with a very brief background of drug addiction might find this to be an appropriate option whereas somebody with a more extensive and critical history of alcohol and drug abuse might be in need of a more extensive course of treatment. If somebody evidently has a more serious history of abuse and decides to choose a residential short-term rehabilitation program of as little as 4 weeks, it is often suggested that the individual receive typical follow-up treatment or take part in an aftercare program so that their progress can be monitored and so can receive the support needed in their rehabilitation process as much as feasible.
