Prevalence of Marijuana Use in Lifetime, Past Year, and Past Month among Persons in the US Aged 12 or Older, by Demographic Characteristics: Number in Thousands
" Marijuana/hashish was reported as the primary substance of abuse by 14 percent of TEDS admissions aged 12 and older in 2015 [Table 1.1b].
" The average age at admission for primary marijuana/hashish admissions was 26 years [Table 2.1b]. Thirty-one percent of marijuana/hashish admissions were under age 20 (vs. 7 percent of all admissions combined), and primary marijuana/hashish abuse accounted for 78 percent of admissions aged 12 to 14 and 75 percent of admissions aged 15 to 17 years [Table 2.1c].
Estimated Prevalence of Cannabis Dependence or Abuse in the US
"In 2016, 28.6 million people aged 12 or older used an illicit drug in the past 30 days, which corresponds to about 1 in 10 Americans overall (10.6 percent) but ranges as high as 1 in 4 for young adults aged 18 to 25. Regardless of age, the illicit drug use estimate for 2016 continues to be driven primarily by marijuana use and the misuse of prescription pain relievers. Among people aged 12 or older, 24.0 million were current marijuana users and 3.3 million were current misusers of prescription pain relievers.
" In 2013, among the 20.2 million persons aged 12 or older who were classified as needing substance use treatment but not receiving treatment at a specialty facility in the past year, 908,000 persons (4.5 percent) reported that they perceived a need for treatment for their illicit drug or alcohol use problem (Figure 7.10). Of these 908,000 persons who felt they needed treatment but did not receive treatment in 2013, 316,000 (34.8 percent) reported that they made an effort to get treatment, and 592,000 (65.2 percent) reported making no effort to get treatment.
