Many individuals looking into alcohol and drug rehab in Knox may choose to take part in a residential short-term drug rehab center which only demands a stay of as little as 4 weeks. This may sometimes be an acceptable rehab for individuals who have family or job obligations, and may just require a quick but intense course of rehab. Additionally, people with a very brief history of drug and alcohol addiction may find this to be an appropriate choice whereas somebody in Knox who has a more extensive and lengthy case of abuse and addiction may need a more in depth length of time in treatment. If somebody is known to have an extensive background of drug and alcohol abuse and decides to choose a Knox residential short-term rehabilitation program of 30 days or less, it is often encouraged that they receive typical follow-up care or participate in an aftercare plan so that their progress can be verified and so they can be supported in their rehabilitation process as often as possible.
