The annual survey was released on Friday by the Substance Abuse and Mental Health Services Administration (SAMHSA) and includes data on mental health and substance use among Americans. Serious mental illness is also reportedly increasing among adults 18-49 years old. The report concluded that substance abuse and mental disorders are common among throughout the U.S. Those with serious mental illness are more likely to misuse substance, as individuals misusing substances are likely to experience mental health issues, according to the survey. “Increases in marijuana and methamphetamine use and in serious mental illness are very concerning, and we expect that these challenges will be exacerbated by this year’s pandemic," Azar said. “The NSDUH data provide a foundation that helps to focus resources to address the important areas of mental health and substance use issues in our nation,” said Dr. Elinore McCance-Katz, assistant secretary for Mental Health and Substance Use.
