- Phencyclidine use continues despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of phencyclidine use (e.g., arguments with a spouse about consequences of intoxication; physical fights).
- Important social, occupational, or recreational activities are given up or reduced because of phencyclidine use.
- Recurrent phencyclidine use takes place in situations where it is physically hazardous (e.g., driving a car or operating a machine)
- Phencyclidine use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to be caused or exacerbated by the drug.
- Tolerance has been built up, as defined as either of the following:
- A need for markedly increased amounts of phencyclidine to achieve intoxication or desired effect.
- A markedly diminished effect with continued use of the same amount of phencyclidine.
