Definition: Percentage of public school students reporting the number of days in which they drank alcohol on school property in the past 30 days, by grade level. The grade levels included in school district-level data depend on the grades offered in each school district; for example, high school districts do not include 7th grade data. "Non-Traditional" students are those enrolled in Community Day Schools or Continuation Education. According to EdSource, nearly 10% of public school students in California are enrolled in these programs.

Measures of Alcohol, Tobacco, and Other Drugs on Kidsdata.org

On kidsdata.org, most indicators of alcohol, tobacco, and other drug use come from the California Healthy Kids Survey (CHKS) through a partnership with WestEd, which developed and administers the CHKS, and the California Department of Education. These indicators include:

Most of these indicators are available by gender, grade (7th, 9th, and 11th), race/ethnicity, and level of connectedness to school. School connectedness is a summary measure that includes being treated fairly, feeling close to people, feeling happy, feeling part of school, and feeling safe at school. 

Additionally, an indicator of children living in households with smokers is available for California, the Bay Area, and Los Angeles County based on a 2010 survey of parents.

Why This Topic Is Important

Youth alcohol, tobacco or other drug use is associated with a wide range of health, social and academic challenges. For example, teen alcohol use has been linked to risky health behaviors (e.g., unprotected sex), poor academic performance, physical and/or dating violence, motor vehicle accidents, crime, and suicide attempts (1, 2). Excessive alcohol consumption that continues into adulthood can have long-term consequences as well, including liver disease, cancer, and cardiovascular disease (3, 4). Cigarette smoking during the teen years also is related to risky behaviors, such as drinking and other drug use; cigarette smoking that is sustained over time is related to a variety of physical health problems later in life (e.g., cancer, heart disease, and respiratory illness) (5, 6). Marijuana use can adversely affect health in both the short- and long-term. Specifically, smoking marijuana can cause anxiety attacks, memory impairment, coordination loss, increased heart rate, breathing problems, and/or cognitive deficits (7). The use of marijuana by teens also is associated with poorer academic performance and delinquent and aggressive behavior (7).

According to 2011 data, 6.6% of U.S. 12th graders reported using marijuana daily, an increase from 5.8% in 2001. Youth reports of daily cigarette use are more common, with 10.3% of 12th graders reporting daily use in 2011 although this percentage has declined dramatically (by more than 45%) over the past decade. A small percentage (2.1%) of 12th graders reported daily alcohol use in 2011, but 40.0% reported any use within the past month. Both of these figures have declined since 2001; daily alcohol use dropped by 42% and any use within the past month decreased by 20% (8, 9).

Policy Implications

Public policy can promote early identification of known risk factors for youth substance use, such as aggressive behavior, poverty, lack of parental supervision, school failure, drug availability, and substance abuse by peers (1, 2). It also can promote protective factors, such as school connectedness, family economic stability, and academic success (1, 2). Early intervention can be effective, especially when specifically tailored to the population and risk factors (2). Controlling youth smoking requires particular attention to mass media and marketing (4).

According to research and subject experts, policy options for addressing alcohol, tobacco, and other drug use by youth include:

  • Ensuring adequate funding for age-appropriate treatment of heavy substance use, and ensuring that substance abuse and mental health insurance benefits are sufficient in amount and scope to be effective (1, 5)
  • Prioritizing early identification of risk factors correlated with substance use, especially among middle school-age youth, many of which can be documented by schools (1, 2, 5)
  • Developing school and community-wide policies to promote school and community “connectedness” among youth (2, 3)
  • Promoting youth-focused, mass media counter-marketing strategies to combat tobacco advertising and appealing depiction in the media; and limiting tobacco marketing and sales to keep cigarettes out of the hands of youth (4)

How Children Are Faring

Most 7th, 9th, and 11th graders in California say that they have not used alcohol, cigarettes, or marijuana in the past month. In 2008-10, about 25% of 9th graders and 34% of 11th graders reported using alcohol in the past 30 days. When asked if they had ever consumed alcohol, nearly half (46%) of 9th graders and almost two-thirds (62%) of 11th graders reported having at least one full drink in their lifetime, according to 2008-10 data. Percentages typically are lower for reported cigarette use, marijuana use, and recreational use of prescription drugs. Non-traditional students, those enrolled in Community Day Schools or continuation education, are at highest risk for using these substances. Students who report feeling less connected to their schools also report higher levels of alcohol, tobacco, and other drug use.

Although a small percentage of students report the very highest level of use of alcohol, cigarettes, and marijuana (20 days or more of use in the past 30 days), that proportion increased statewide between 2004-06 and 2008-10; this was true for nearly all grades and types of drugs, as well as for both boys and girls.

According to a 2010 survey of California parents, most children in the state (85%) live in smoke-free households. Low-income children are less likely to live in smoke-free homes than higher-income children.
