According to DSM-5, what are key criteria for diagnosing a substance use disorder?

The key criteria for diagnosing a substance use disorder, as outlined in the DSM-5, include impaired control, social impairment, risky use, and pharmacological criteria. These criteria provide a comprehensive framework for assessing the severity and impact of substance use on an individual's life.

Impaired control refers to the inability to cut down or control substance use despite a desire to do so. Social impairment involves difficulties in fulfilling obligations at work, school, or home, which can stem from substance-related issues. Risky use highlights engaging in behaviors that pose a threat to one's safety or the safety of others while under the influence or in pursuit of substances. Finally, pharmacological criteria include tolerance (needing more of the substance to achieve the desired effect) and withdrawal symptoms when not using the substance.

These elements together form a multidimensional view of substance use problems, encapsulating not only the behavioral aspects but also the broader social ramifications and physical dependencies that may arise. This approach allows for a nuanced understanding of an individual's relationship with substances, guiding effective treatment strategies.
