Many individuals who will need drug and alcohol treatment in Harvard may opt for an inpatient short-term alcohol and drug rehabilitation center that demands a stay of 30 days or less. This might be a suitable treatment option for persons that have personal or office commitments, and only require a brief but intensive course of treatment. Moreover, people that have a very short history of alcohol and drug abuse might find that this may be a valid option whereas somebody struggling with a more extensive and critical case of abuse and addiction might need a much more in depth course of treatment. If someone does have a more serious background of abuse and opts for a residential short-term treatment program of as little as 4 weeks, it is very often required that the person follow up this treatment with typical follow-up treatment or take part in an aftercare program in which their progress can be supervised closely and so can receive the support needed in their rehabilitation process as often as possible.
