This accompanies cessation of cannabis use that has been heavy and prolonged (i.e., usually daily or almost daily use over a period of at least a few months). Three or more of the following signs and symptoms develop within approximately 1 week after cessation of heavy, prolonged use:
At least one of the following physical symptoms causing significant discomfort: abdominal pain, shakiness/tremors, sweating, fever, chills, or a headache.
The signs or symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
The signs or symptoms are not attributable to another medical condition and are not better explained by another mental disorder, including intoxication or withdrawal from another substance.
Cannabis-induced Psychotic Disorder
Presence of delusions or hallucinations.
Evidence from the history, physical examination, or laboratory findings of either one of the following:
The symptoms in the first criterion developed during or soon after cannabis intoxication or withdrawal.
The disturbance is not accounted for by a psychotic disorder that is not substance-induced.
Evidence that the symptoms are accounted for by a psychotic disorder that is not substance induced might include the following:
The symptoms precede the onset of substance use (or medication use).
The symptoms persist for a substantial period (e.g., about a month) after the cessation of acute withdrawal or severe intoxication or are substantially more than what would be expected, given the type or amount of the substance used or the duration of use.
Other evidence suggests the existence of an independent nonsubstance-induced psychotic disorder (e.g., a history of recurrent nonsubstance-related episodes).
The disturbance does not occur exclusively during delirium.
The disturbance causes clinically significant distress or impairment in social, occupational, or other areas of functioning.
Cannabis-induced Anxiety Disorder
Panic attacks or anxiety predominate in the clinical picture.
Evidence from the history, physical examination, or laboratory findings of either of the following:
The symptoms in the first criterion developed during or soon after substance intoxication or withdrawal.
The disturbance is not better accounted for by an anxiety disorder that is not substance-induced. Evidence that the symptoms are better accounted for by an anxiety disorder that is not substance induced might include the following:
The symptoms precede the onset of substance use.
The symptoms persist for a substantial period (e.g., about a month) after cessation of acute withdrawal or severe intoxication or are substantially more than expected given the type or amount of the substance used or the duration of use.
Other evidence suggests the existence of an independent nonsubstance-induced anxiety disorder (e.g., a history of recurrent nonsubstance-related episodes).
The disturbance does not occur exclusively during delirium.
The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.
