Which ethnic groups have the highest rates of illicit drug dependence?

The selection of Native Americans and Alaska Natives, along with African Americans, as the ethnic groups with the highest rates of illicit drug dependence is supported by various studies and reports addressing substance use and mental health statistics. These groups have faced numerous historical and systemic challenges, such as socio-economic disadvantages, marginalization, and unequal access to healthcare, which contribute to higher rates of drug dependence.

Research findings indicate that Native American and Alaska Native populations demonstrate significant substance use issues, often stemming from multifaceted factors, including cultural dislocation, trauma, and limited access to community resources and preventative interventions. African American communities also experience higher rates of drug dependence, affected by socioeconomic disparities and a range of systemic barriers that can exacerbate substance use problems.

Contrarily, other groups listed in the options, such as Caucasians, Hispanics, Asians, and Pacific Islanders, have varying rates of drug dependence, but the evidence points to their prevalence being lower compared to Native American, Alaska Native, and African American populations in specific contexts. It's essential to approach these statistics with an understanding of the broader social conditions and systemic issues that contribute to these trends in drug dependence.
