In the review of the use of substance disorder detection and the making of treatment plan understanding of tolerance and withdrawal is an important factor. A clear understanding of tolerance is a person’s diminished response that results in repeated substance use. Tolerance and withdrawal are not part of the diagnosis but are more of a clinical courses for past withdrawal symptoms. Tolerance and dependence are terms often mistaken by the counselors to be the same. However, having a clear distinction could lead to a better understanding of the dangers of substance use (Stevens, Smith & Reiner, 2009). Lack of knowledge could lead to a distorted treatment plan, a not well-convinced treatment plan, and under convince the client on what to do or rather expect at withdrawal. The client could not be aware of medical conditions due to tolerance from the use of a substance. The longer the use of substance the more substance-related problems. For instance, a patient who started using substance at a younger age means he/she has used more of the substance in their lifetime. As such,  there will be more side effects to be put into consideration while planning their plan of treatment. It is important for the counselor to note that a patient can suffer from tolerance in both prescription medications and illicit drugs.
A patient’s well-being and detoxification process can be affected when he/she undergoes psychological and medical conditions. It may be medical conditions that preexisted and are not related to the use of the substance. However, the co-occurring disorder can be affected negatively by the detoxification process or vice versa. In addition, many people who use substances present with a medical condition in a medical crisis or in the advanced stage. Use of substance is more likely to exacerbate the co-occurring mental disorders.
