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).

A substance related disorder is a condition in which an individual uses or abuses a substance till a point of satisfaction where it leads to maladaptive behaviour, manifested by at least one symptom that interferes with normal life functioning within a 12 month period. [1] Diagnostic criteria for substance dependence requires at least three of the following during a 12 month period: development of tolerance to the substance, withdrawal symptoms, persistent desire/unsuccessful attempts to stop using the substance, ingestion of larger amounts of substance, declined life functioning, and persistent use of substance. [1] Substance abuse is most prevalent among people 18 to 25 years of age and is also more common in males than females and in urban residents compared to those who live in rural areas. [1] Over 50 percent of individuals with substance abuse issues have another psychiatric disorder, something that is termed Comorbid Psychiatric Diagnosis. [1] Substance abuse can manifest in a variety of ways, differing in terms of the substance abused, the pattern of use and the comorbid illness present. [1] Commonly abused substances include alcohol, stimulants, sedatives/hypnotic drugs, opioids, hallucinogens, "designer drugs", inhalants and marijuana. [1]

Substance-related disorders can be subcategorized into "substance use disorders" (SUD) and "substance-induced disorders" (SID).[2][3]

Though DSM-IV makes a firm distinction between the two, SIDs often occur in the context of SUDs.[4]

Some people can have strong drug cravings even after they have not used the drug for a long period of time. They call this being "clean". To figure out how the brain triggers these cravings they have done multiple test on mice.[5]

Substance use disorders include substance abuse and substance dependence.[8] In DSM-IV, the conditions are formally diagnosed as one or the other, but it has been proposed that DSM-V combine the two into a single condition called "Substance-use disorder"._APA_DSM-5-9|[9]
