A substance-related disorder is an umbrella term used to describe several different conditions (such as intoxication, harmful use/abuse, dependence, withdrawal, and psychoses or amnesia associated with the use of the substance) associated with several different substances (such as alcohol or opiods).
Substance-related disorders can be subcategorized into “substance use disorders” (SUD) and “substance-induced disorders” (SID).
Though DSM-IV makes a firm distinction between the two, SIDs often occur in the context of SUDs.
