Paradoxically, drug intoxications also must be ruled out, because, for example, lethargy may indicate withdrawal from one drug or intoxication with another drug.
As with all substance-related disorders, adolescent conduct disorder, adult antisocial per- sonality disorder, and other substance use disorders likely co-occur with other (or un- known) substance withdrawal.
Because the category of other or unknown substances is inherently ill-defined, the extent and range of induced disorders are uncertain. Nevertheless, other (or unknown) sub- stance—induced disorders are possible and are described in other chapters of the manual with disorders with which they share phenomenology (see the substance/medication- induced mental disorders in these chapters): other (or unknown) substance—induced psy- rocognitive disorder (”Neurocognitive Disorders”). For other (or unknown) substance— delirium, see the criteria and discussion of delirium in the chapter "Neurocognitive Dis- orders.” These other (or unknown) substance—induced disorders are diagnosed instead of only when the symptoms are sufficiently severe to warrant independent clinical attention.
292.9 (F19.99)
This category applies to presentations in which symptoms characteristic of an other (or un- in social, occupational, or other important areas at functioning predominate but do not meet the full criteria for any specific other (or unknown) substance—related disorder or any of the disorders in the substance—related disorders diagnostic class.

Specify if:
In early remission: After tull criteria for gambling disorder were previously met, none of the criteria for gambling disorder have been met for at least 3 months but for less than 12 months.

Mlld: 4—5 criteria met.
Moderate: 6—7 criteria met.
