DSM-III

A. Either a pattern of pathological use or impairment in social or occupational functioning due to cannabis use.

  • Pattern of pathological use: intoxication throughout the day; use of cannabis nearly ever day for at least a month; episodes of Cannabis Delusional Disorder.
  • Impairment in social or occupational functioning due to cannabis use: e.g., marked loss of interest in activities previously engaged in, loss of friends, absence from work, loss of job, or legal difficulties (other than a single arrest due to possession, purchase, or sale of an illegal substance).

B. Tolerance: need for markedly increased amounts of cannabis to achieve the desired effect with regular use of the same amount.

DSM-IV

For more information, see Substance Dependence

Individuals with Cannabis Dependence have compulsive use and do not generally develop physiological dependence, although tolerance to most of the effects of cannabis has been reported in individuals who use cannabis chronically. There have also been some reports of withdrawal symptoms, but they have not yet been reliably shown to be clinically significant. Individuals with Cannabis Dependence may use very potent cannabis throughout the day over a period of months or years, and they may spend several hours a day acquiring and using the substance. This often interferes with family, school, work, or recreational activities. Individuals with Cannabis Dependence may also persist in their use despite knowledge of physical problems (e.g., chronic cough related to smoking) or psychological problems (e.g., excessive sedation resulting from repeated use of high doses).
