"To estimate the prevalence of chronic pain and high-impact chronic pain in the United States, CDC analyzed 2016 National Health Interview Survey (NHIS) data. An estimated 20.4% (50.0 million) of U.S. adults had chronic pain and 8.0% of U.S. adults (19.6 million) had high-impact chronic pain, with higher prevalences of both chronic pain and high-impact chronic pain reported among women, older adults, previously but not currently employed adults, adults living in poverty, adults with public health insurance, and rural residents."
"Summarizing data from six large studies, one analysis estimated that the proportion of the United States adult population that is in remission from a substance use disorder of any severity is approximately 10.3 percent (with a range of 5.3 to 15.3 percent).29 This estimate is consistent with findings from a different national survey, which found that approximately 10 percent, or 1 in 10, of United States adults say, 'Yes,' when asked, 'Did you once have a problem with drugs or alcohol but no longer do?' These percentages
"In 2012–2013, the NESARC-III [National Epidemiologic Survey on Alcohol and Related Conditions–III], a large national survey of US adults, assessed 12-month and lifetime disorders, including DUDs, diagnosed according to the new DSM-5. The NESARC-III used rigorous survey and field methods and incorporated measures of functioning and detailed assessments of treatment use. The NESARC-III results indicate that the prevalence rates of 12-month and lifetime DSM-5 DUD were 3.9% and 9.9%, respectively, representing approximately 9,131,250 and 23,310,135 US adults, respectively.
According to the National Survey on Drug Use and Health (NSDUH), in 2008-2009, an estimated 13.37% of young people in the US aged 12 through 17 had used marijuana in the past year, falling to 12.29% in 2015-2016. The NSDUH also estimates that, in 2008-2009, an estimated 7.03% of young people in the US aged 12 through 17 had used marijuana in the past month, dropping to 6.75% in 2015-2016.
"In 2016, an estimated 44.7 million adults aged 18 or older had AMI [Any Mental Illness] in the past year (Figure 54). This number represents 18.3 percent of adults in the United States. An estimated 10.4 million adults in the nation had SMI [Serious Mental Illness] in the past year, and 34.3 million adults had AMI excluding SMI in the past year. The number of adults with SMI represents 4.2 percent of adults in 2016, and the number of adults with AMI excluding SMI represents 14.0 percent of adults.
"The joint UNODC/WHO/UNAIDS/World Bank estimate for the number of people who inject drugs (PWID) for 2014 is 11.7 million (range: from 8.4 to 19.0 million), or 0.25 per cent (range: 0.18-0.40 per cent) of the population aged 15-64.
"In 2018, an estimated 5.5 million people aged 12 or older were past year users of cocaine (Figure 10), including about 757,000 users of crack. Stated another way, about 2.0 percent of the population in 2018 used cocaine (Figure 13), and 0.3 percent used crack (2018 DT 7.2).
"In the thirteen-year (2004–2016) combined sample of young adults aged 21–30, 1.5% report having ever used any drug by injection not under a doctor’s orders, and 0.5% reported doing so on 40 or more occasions (Table 4-1a). Thus, about 1 in every 67 respondents has ever used an illicit drug by injection, and about 1 in every 200 respondents reports an extended pattern of use as indicated by use on 40 or more occasions. There is a fair-sized gender difference -- 2.3% of males vs. 0.9% of females indicate ever injecting a drug.
"In these initial investigations, we found no evidence that I-502 enactment, on the whole, affected cannabis abuse treatment admissions. Further, within Washington State, we found no evidence that the amount of legal cannabis sales affected cannabis abuse treatment admissions.
"The bulk of outcome analyses in this report used the within-state approach to focus on identifying effects of the amount of legal cannabis sales. We found no evidence that the amount of legal cannabis sales affected youth substance use or attitudes about cannabis or drug-related criminal convictions.
" In 2013, 4.7% of Australians aged 14 or older had misused a pharmaceutical in the previous 12 months, which was a significant rise from 4.2% in 2010. This increase was only significant for males (from 4.1% in 2010 to 5.1% in 2013 and from 4.2% to 4.4% for females).
" The rise in pharmaceutical misuse was mainly due to an increase in males in their 30s (4.5% in 2010 to 6.9% in 2013) and females in their 40s (3.1% in 2010 to 4.5% in 2013) misusing these drugs.
