C. Two or more of the following signs, developing 2 hours of cannabis use:

Specify if:

• With Perceptual Disturbances

• This specifier may be noted when hallucinations with intact reality testing or auditory, visual, or tactile illusions occur in the absence of a delirium. Intact reality testing means that the person knows that the hallucinations are induced by the substance and do not represent external reality. When hallucinations occur in the absence of intact reality testing, a diagnosis of Substance-Induced Psychotic Disorder, With Hallucinations, should be considered

• When cannabis is smoked, intoxication develops within minutes; however, if cannabis is ingested orally, intoxication may take a few hours to develop.
• Effects of cannabis intoxication usually last 3-4 hours. The effects may last longer if the cannabis was ingested orally.
• The behavioral and psychological changes that occur depend of the dose, the administration, and the individual. For example, a person’s tolerance, rate of absorption and sensitivity will differ greatly 23. Other (or Unknown) Substance-Related Disorders
