"In 2018, an estimated 164.8 million people aged 12 or older used a substance (i.e., tobacco, alcohol, or an illicit drug) in the past month (Figure 1). This number of current substance users corresponds to 60.2 percent of the population. About 2 out of 5 people aged 12 or older (108.9 million, or 39.8 percent) did not use substances in the past month.
" Among pregnant women aged 15 to 44, 5.4 percent were current illicit drug users based on data averaged across 2012 and 2013. This was lower than the rate among women in this age group who were not pregnant (11.4 percent). Among pregnant women aged 15 to 44, the average rate of current illicit drug use in 2012-2013 (5.4 percent) was not significantly different from the rate averaged across 2010-2011 (5.0 percent).
"As noted in the illicit drug use section, an estimated 24.0 million Americans aged 12 or older in 2016 were current users of marijuana (Figure 15). This number of past month marijuana users corresponds to 8.9 percent of the population aged 12 or older (Figure 17). The percentage of people aged 12 or older who were current marijuana users in 2016 was higher than the percentages from 2002 to 2015.
"In 2016, 71.8 percent of youths aged 12 to 17 who were enrolled in school in the past year reported having seen or heard drug or alcohol use prevention messages at school (Figure 10). This percentage was lower than the percentages in 2002 to 2013, but it was similar to the percentages in 2014 and 2015. In 2002, for example, 78.8 percent of adolescents who were enrolled in school reported exposure to substance use prevention messages at school.
"In 2016, about 1 in 9 youths aged 12 to 17 (11.4 percent) reported that they had participated in alcohol, tobacco, or drug use prevention programs outside of school in the past year (Table A.4B in Appendix A). This estimate was similar to the percentages in 2004 to 2015, but it was lower than the percentages in 2002 and 2003. Nevertheless, in any given year since 2002, the majority of youths did not participate in prevention programs outside of school in the past year."
"In 2017, about 1 in 4 people aged 12 or older (24.5 percent) were current binge alcohol users (Figure 7). This percentage corresponds to about 66.6 million binge drinkers who were aged 12 or older (Figure 5). About 1.3 million adolescents aged 12 to 17 were past month binge drinkers, which corresponds to 5.3 percent of adolescents. Thus, about 1 in 20 adolescents aged 12 to 17 in 2017 were current binge drinkers. An estimated 36.9 percent of young adults aged 18 to 25 were binge drinkers in the past month, which corresponds to about 12.7 million young adults.
"In 2017, 140.6 million Americans aged 12 or older were current alcohol users, 66.6 million were binge drinkers in the past month, and 16.7 million were heavy drinkers in the past month (Figure 5). Thus, nearly half of current alcohol users were binge drinkers (47.4 percent), and 1 in 8 current alcohol users were heavy drinkers (11.9 percent). Among binge drinkers, about 1 in 4 (25.1 percent) were heavy drinkers.24
