of the 10 diagnostic criteria in the past year.
Inhalant-induced disorders (i .e., inhalant-induced psychotic disorder, depressive dis-
order, anxiety disorder, neurocognitive disorder, other inhalant-induced disorders)
without meeting criteria for inhalant use disorder. Criteria are met for a psychotic, de-
pressive, anxiety, or major neurocognitive disorder, and there is evidence from history,
physical examination, or laboratory findings that the deficits are etiologically related to
the effects of inhalant substances. Yet, criter ia for inhalant use disorder may not be met
(i.e., fewer than 2 of the 10 criteria were present).
Other substance use disorders, especially those involving sedating substances (e.g.,
alcohol, benzodiazepines, barbiturates). Inhalant use disorder commonly co-occurs
with other substance use disorders, and the sy mptoms of the disorders may be similar and
overlapping. To disentangle symptom patterns, it is helpful to inquire about which symp-
toms persisted during periods when some of the substances were not being used.
Other toxic, metabolic, traumatic, neoplastic, or infectious disorders impairing central or
peripheral nervous system function. Individuals with inhalant use disorder may pre-
sent with symptoms of pernicious anemia, su bacute combined degeneration of the spinal
cord, psychosis, major or minor cognitive d isorder, brain atrophy, leukoencephalopathy,
and many other nervous system  disorders. Of co urse, these disorder s also may occur in
the absence of inhalant use disorder. A history of little or no inhalant use helps to exclude
inhalant use disorder as the source of these problems.
Disorders of other organ systems. Individuals with inhalant use disorder may present
