Alcohol Use v Marijuana Use - US Youth and "The Displacement Hypothesis"

(Alcohol Use v Marijuana Use - US Youth and "The Displacement Hypothesis") "Alcohol and marijuana are the two most commonly used substances by teenagers to get high, and a question that is often asked is to what extent does change in one lead to a change in the other. If the substances co-vary negatively (an increase in one is accompanied by a decrease in the other) they are said to be substitutes; if they co-vary positively, they are said to be complements.

Prevalence of Substance Use Among Youth in the US, by Race/Ethnicity

"For a number of years, 12th grade African-American students reported lifetime, annual, 30-day, and daily prevalence levels for nearly all drugs that were lower – sometimes dramatically so – than those for White or Hispanic 12th graders. That is less true today, with levels of drug use among African Americans more similar to the other groups. This narrowing of the gap between African Americans and other racial/ethnic groups is also seen in 8th and 10th grade, indicating that this narrowing in 12th grade is almost certainly not due primarily to differential dropout rates.

Illegal or Improper Use of Prescription Drugs by High School Students in the US, by Gender

"Nationwide, 14.0% of students had taken prescription pain medicine (counting drugs such as codeine, Vicodin, OxyContin, Hydrocodone, and Percocet) without a doctor’s prescription or differently than how a doctor told them to use it one or more times during their life (Supplementary Table 127)). The prevalence of having ever taken prescription pain medicine without a doctor’s prescription or differently than how a doctor told them to use it was higher among Hispanic (15.1%) than black (12.3%) students and higher among Hispanic female (16.1%) than black female (12.5%) students.

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.
