All the following describe substance use disorder except:

Substance use disorder (SUD) is characterized by patterns of substance use that lead to significant impairment or distress. The correct answer highlights that not 20% of the general population has been diagnosed with SUD; in fact, estimates typically indicate lower prevalence rates, often around 8-10% in various studies. This figure can fluctuate based on specific populations and definitions used, making the 20% claim misleading.

The other aspects described are consistent with the characteristics of SUD. Physical dependence often occurs, where individuals develop tolerance and experience withdrawal symptoms. Moreover, professional treatment is typically necessary for recovery, as SUD can be complex and difficult to overcome without support. Finally, social consequences are a hallmark of SUD, as the disorder often leads to strained relationships, legal issues, and occupational challenges. Thus, the statement regarding the prevalence of diagnosis stands out as incorrect in the context of SUD definitions and what is commonly observed in the population.
