Clinicians must detect at least three of the following 11 symptoms to diagnose a substance use disorder:
- Growing tolerance for a substance, marked by a pattern of escalating usage
- Withdrawal symptoms that appear between dosages
- Drinking or drug use sessions that last longer or involve greater consumption than planned
- Multiple failed attempts to stop using drugs or alcohol
- Significant time spent using drugs or alcohol, obtaining supplies, or recovering from substance use episodes
- Physical and psychological cravings are experienced
- Recurrent substance use that causes the person to neglect family, work, school, or personal responsibilities
- Substance use that continues despite its role in causing social and interpersonal conflicts
- Favored hobbies and other important activities abandoned in favor of drugs or alcohol
- Drugs and alcohol used and abused in situations or contexts where it creates physical danger
- Substance use that continues even though it is implicated in the onset or worsening of mental or physical health problems
