Statistics and other data regarding drug use and other risk-taking behavior among young people, as well as drug policies related to young people including prevention, education, social development, healthcare, mental health, and criminal justice.

Lifetime Marijuana Use Among Students in the US, by Race and Gender

"Nationwide, 35.6% of students had used marijuana (also called grass, pot, or weed) one or more times during their life (Supplementary Table 106). The prevalence of having ever used marijuana was higher among black (42.8%) and Hispanic (42.4%) than white (32.0%) students, higher among black female (44.9%) and Hispanic female (42.7%) than white female (32.1%) students, and higher among black male (40.5%) and Hispanic male (42.1%) than white male (31.7%) students.

Mortality Among High School Students in the US

"In 2016 in the United States, 74% of all deaths among persons aged 10–24 years resulted from four causes: motor vehicle crashes (22%), other unintentional injuries (20%), suicide (17%), and homicide (15%) (1). Among persons aged 15–19 years, 209,809 births (2); 488,700 cases of chlamydia, gonorrhea, and syphilis (3); and 1,652 diagnoses of human immunodeficiency virus (HIV) (4) were reported. Among persons aged ≥25 years, 54% of all deaths in the United States resulted from cardiovascular disease (31%) and cancer (23%) (1).

Perceived Availability of Drugs Among Young People in the US

"• In 2017, 46% of 8th graders and 63% of 10th graders thought that cigarettes would be fairly easy or very easy for them to get if they wanted some. In 2017 for the first time we asked about availability of cigarettes among 12th graders; 78% reported they would be fairly easy or very easy to get. A growing interest among state and local governments to increase the minimum age to 21 for the purchase of tobacco products suggests that availability may decrease for this age group in the coming years.

Risk Factors for Substance Use by Young People

Risk Factors for Substance Use by Young People: "The risk factors were stronger predictors of substance use outcomes compared to the protective factors, regardless of grade level or substance use type. In particular, the individual and peer risk factors were strongly related to lifetime and recent use of cigarettes, alcohol, and marijuana. Among the protective factors, the strongest associations with substance use were found in the community domain. Several age-related differences in the associations were also found, suggesting that family and community factors were more salient among younger grades whereas peer and school factors were stronger among older adolescents."

Alcohol and Tobacco Use by Young People as Gateway Factors for Eventual Use of Other Drugs

"• In 2013, the rate of current illicit drug use among youths aged 12 to 17 who smoked cigarettes in the past month was approximately 9 times the rate among youths who did not smoke cigarettes in the past month (53.9 vs. 6.1 percent). Also, the rate of current marijuana use in 2013 among youths aged 12 to 17 who smoked cigarettes in the past month was about 11 times the rate among youths who did not smoke cigarettes (49.5 vs. 4.6 percent).

Cannabis and Adolescent Motivation

Cannabis and Adolescent Motivation: "The apparent strength of these relationships in cross-sectional studies (e.g. Kandel, 1984) has been exaggerated because those adolescents who are most likely to use cannabis have lower academic aspirations and poorer high school performance prior to using cannabis than their peers who do not (Newcombe and Bentler, 1988). It remains possible that factors other than the marijuana use account for apparent causal relations.
