Many individuals in need of alcohol and drug rehab in Knox may opt for a residential short-term drug treatment center that only calls for a stay of as little as 4 weeks. This may be a suitable rehabilitation choice for individuals who have personal or office responsibilities, and may require a brief but intensive course of rehabilitation. Furthermore, people that have a very brief background of alcohol and drug abuse may possibly find this to be a suitable option whereas a person struggling with a more significant and serious case of substance abuse might need a more intensive time spent in rehab. If somebody evidently has a more serious background of drug and alcohol abuse and chooses a residential short-term rehabilitation program of as little as 4 weeks, it is frequently required that the person follow up this treatment with standard follow-up treatment or move to an aftercare facility so that their progress can be supervised closely and so they can be supported in their rehab process as much as feasible.
