Addiction disorder is a widespread problem in modern society. In the past, it was approached in a general manner and patients were treated with standardized procedures. Recent developments in treatment and medications allow health care providers to deploy targeted solutions. No two cases of addiction disorder are similar; therefore, their treatment should also vary. Through substance abuse evaluations, care providers are able to figure out precisely what kind of treatment is needed. It's a kind of evaluation that reveals information useful in developing a targeted treatment protocol. It generally comprises two stages: screening and assessment. The screening process determines the extent, scope and severity of the addiction, and the assessment process is to develop a suitable plan.
