There are 2 groups of substance related disorders: Substance Use Disorders such as
dependence and abuse and Substance-Induced Disorders such as intoxication,
withdrawal and substance-induced other mental illnesses (delirium, sleep
disorder all due to use of substance)
Substance dependence is more classified by increased
tolerance and withdrawal symptoms if use is stopped. Abuse is when the use of
the substance impairs or distresses role obligations, the person uses in
physically hazardous conditions, leads to legal problems, and impairment in
relationships due to use/abuse.
Substance-Induced disorders are also broken down into
substance such as alcohol, caffeine, amphetamine, cannabis, cocaine,
hallucinogens, inhalant, nicotine, opioid, phencyclidine, sedative, hypnotic,
or anxiolytic, polysubstance (3 groups of substances), and other.
