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:

Why This Topic Is Important

Youth alcohol, tobacco or other drug use is associated with a wide range of negative health, social and academic outcomes. For example, teen alcohol use has been linked to risky health behaviors (e.g., other drug use and unprotected sex), poor academic performance, physical and/or dating violence, motor vehicle accidents, crime, and suicide attempts (1, 2). Excessive alcohol consumption 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, and 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).

National data indicate that while the prevalence of daily marijuana use among 8th, 10th, and 12th graders increased by 14% between 2001 and 2011, daily alcohol use decreased by 42%, and daily cigarette smoking decreased by 46% (8). Of all states, California had the third lowest percentage of youth ages 12-17 who smoke, according to 2006-07 data (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, according to survey data in recent years. 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 2008-2010 data. Percentages typically are lower for reported cigarette and marijuana use. Non-traditional students, those enrolled in Community Day Schools or continuation education, are at highest risk for using all of 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 from the 2004-06 period to 2006-08; 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.
