Here are the criteria for diagnosing drug addiction:
1. Impaired Control:
- The individual often takes the substance in larger amounts or over a longer period than intended.
- There is a persistent desire or unsuccessful efforts to cut down or control substance use.
2. Social Impairment:
- Substance use results in a failure to fulfill major role obligations at work, school, or home (e.g., repeated absences or poor performance related to substance use).
- Continued substance use despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of the substance.
3. Risky Use:
- The individual continues to use the substance despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance.
4. Pharmacological Criteria:
- Tolerance: The need for markedly increased amounts of the substance to achieve intoxication or desired effect, or a markedly diminished effect with continued use of the same amount.
- Withdrawal: The characteristic withdrawal syndrome for the substance, or the same (or a closely related) substance is taken to relieve or avoid withdrawal symptoms.
5. Compulsive Use:
- The substance is often taken in larger amounts or over a longer period than was intended.
- There is a persistent desire or unsuccessful efforts to cut down or control substance use.
