"On average, 7% of the ESPAD students stated that they had used marijuana or hashish during the past 30 days. As a proportion of the group reporting lifetime use, this corresponds to roughly four in ten. The highest rates of past-30-days cannabis use are found in the two neighbouring countries of France and Monaco (24% and 21%, respectively), followed by the United States (not an ESPAD country) (18 %) and the Czech Republic and Spain (not an ESPAD country) (15% each).
"In 2017, 30.5 million people aged 12 or older used an illicit drug in the past 30 days (i.e., current use), which corresponds to about 1 in 9 Americans (11.2 percent). About 1 in 4 young adults aged 18 to 25 were current illicit drug users. Regardless of age, the estimates of current illicit drug use for 2017 were driven primarily by marijuana use and the misuse of prescription pain relievers.
"The decline in the U.S. correctional population from January 1, 2016 (6,676,200 persons), to December 31, 2016 (6,613,500), continued a downward trend that began in 2008 (table 1). Persons supervised in the community on either probation (3,673,100 persons) or parole (874,800) continued to account for the majority of the U.S. correctional population at year-end 2016. Nearly 7 in 10 persons under correctional supervision were supervised in the community (4,537,100) on December 31, 2016, and 3 in 10 (2,162,400) were incarcerated in state or federal prisons or local jails.1
