Abstract
Plain Language Summary
High school students in the U.S. face the effects of using substances like alcohol, tobacco, and illegal drugs. Our study looked at national survey data to understand how many high school students use these substances and what factors might influence their use. We found that about one in three high school students had used these substances in the past year, and the rate of use increased as students moved from freshman to senior year. Students who argued or fought with their parents, or who were involved in school or group fights, were more likely to use these substances. On the other hand, students who participated in religious activities or held religious beliefs tended to use fewer of these substances. Based on these findings, we believe it is important to create programs that help reduce negative behaviors, like fighting, and provide positive support for students, like participation in religious groups or other community-based programs. By focusing on reducing conflict and promoting healthy, supportive environments, schools and communities can work together to guide students toward better choices and improve their overall well-being.
Introduction
Substance use is a significant public health concern in the United States (U.S.). Data from the 2020 National Survey on Drug Use and Health (NSDUH) indicate that approximately 37 millions of American aged 12 and older reported using illicit drugs within the past month (NCDAS, 2023). Despite concerted efforts by policymakers and prevention organizations, nearly 47% of high school students report using an illegal drug before graduation (NCDAS, 2023). Among adolescents, substance use poses severe risks, impairing cognitive function and reducing the size of critical brain regions such as the hippocampus (Medina et al., 2007). Substance use during adolescence increases the likelihood of future substance use disorders (SUDs) and long-term health complications (Squeglia et al., 2009). Alarmingly, adolescent drug and alcohol use rates continue to rise, underscoring the limitations of existing interventions and the urgent need for further research into risk and protective factors influencing substance use among high school students.
Adolescence represents a critical period of physical and mental development characterized by significant neurological, psychological, and social changes (Bava & Tapert, 2010). During this stage, the brain undergoes substantial growth, including maturation of the prefrontal cortex and white matter connectivity, which are vital for cognitive and behavioral regulation (Bava & Tapert, 2010; Squeglia & Gray, 2016). Adolescents are particularly susceptible to external influences during this phase of neurological development. Increased sensitivity to social perception, emotional stimuli, and external stressors, such as bullying, peer pressure, and parental expectations, can lead to impulsive decision-making and increase the likelihood of substance use (Bozzini et al., 2021).
The factors influencing adolescent substance use are diverse, including individual, familial, and environmental domains. For instance, adolescents exposed to substance use in their households are at a heightened risk of developing SUDs themselves (Bozzini et al., 2021; Lander et al., 2013). Studies have demonstrated that individuals with SUDs are more likely to engage in violent behaviors toward family members, while children in such households often experience neglect and grow up in unhealthy conditions (Chermack et al., 2010; Lander et al., 2013). These conditions can impede healthy development and increase susceptibility to substance use. Although demographic and social determinants of health (SDOH) are well-documented risk factors, less is known about the influence of psychosocial behaviors, social involvement, and environmental conditions, specifically among high school adolescents.
Emerging evidence suggests that social factors, including participation in extracurricular activities, religious involvement, and community behaviors, may influence substance use behaviors among adolescents (Brennan et al., 2017; Fairclough et al., 2024; Kulis et al., 2021). However, existing studies often lack comprehensive analyses that adjust for potential confounding factors across multiple domains. Furthermore, most research does not focus exclusively on high school students, a group particularly vulnerable to the risks associated with substance use. This underscores the need for targeted studies examining specific factors such as academic performance, student behavior, parental involvement, extracurricular engagement, and religious beliefs within this population.
Substance use determinants may also vary depending on the specific substance. For instance, risk factors for alcohol use may differ from those for tobacco or illicit drug use (Gebeyehu & Srahbzu Biresaw, 2021; Le, 2023; Nawi et al., 2021). Although correlations exist among adolescents who use multiple substances, it remains unclear whether common risk factors contribute to these behaviors, particularly in high school populations (Nawi et al., 2021). Identifying shared and substance-specific risk factors is essential for developing targeted interventions to reduce substance use and enhance adolescents’ long-term well-being.
We hypothesize that common factors influence the use of alcohol, tobacco, and illicit drugs among high school adolescents. Using data from the 2022 NSDUH, this study aims to (1) determine the prevalence of substance use among high school students, and (2) identify common risk and protective factors associated with alcohol, tobacco, and illicit drug use in this population.
Methods
Study design and setting
This study employed a cross-sectional design using data from the NSDUH, a nationally representative survey administered annually by the Substance Abuse and Mental Health Services Administration (SAMHSA). The NSDUH targets the civilian, non-institutionalized population in the United States aged 12 years or older. Data for this study was drawn from the 2022 NSDUH dataset, comprising 59,069 participants. As the dataset includes de-identified, publicly available data, this study was exempt from review by the regional institutional review board and classified as non-human subject research.
Inclusion and exclusion criteria
Adolescents aged 12–17 who were currently attending or expected to attend high school (grades 9–12) as full-time students were included in this study. Exclusion criteria applied to participants who:1) were not high school students, (2) were not adolescents, (3) were not full-time students, (4) had unknown full-time student status, or (5) refused to disclose their full-time student status. A detailed flow diagram outlining participant inclusion and exclusion is provided in Figure 1. Shows a detailed study flow diagram.
Outcomes measurement: Alcohol, tobacco, and illicit drug use
The primary outcome measures included imputed data reflecting alcohol, tobacco, or illicit drug use within the past year. Alcohol use was defined from the question “any alcohol use in the past year”. Tobacco use was defined as the use of any tobacco products or nicotine vaping devices. Illicit drug use included substances such as cocaine, heroin, hallucinogens, inhalants, methamphetamine, marijuana (including hashish), and the misuse of prescription drugs such as pain relievers, sedatives, stimulants, and tranquilizers. Misuse of prescription drugs was identified through positive responses indicating use without a prescription, in greater amounts, more frequently, for longer periods, or in any manner not directed by a physician.
Risk and protective factors of substance use
The six adolescent-specific domain categories are: academic engagement and performance, student antisocial behavior, youth enrichment activities, religious involvement, parental involvement, and substance use prevention education. Table 1 summarizes the variables included in each domain and their respective measurements. A “positive” classification for a domain required at least one affirmative response within the category, whereas a “negative” classification was assigned when all responses within the category were negative. (1) Academic engagement and performance (referred to as school performance) included school engagement (liking school), teacher’s encouragement/praise, average grades, and school attendance (e.g., skipping school). (2) Student antisocial behavior (referred to as antisocial behavior) included arguing/fighting with parents, involvement in school fights, and participation in group fights. (3) Youth enrichment activities included participation in youth activities, problem-solving, communication skills, and self-esteem programs. (4) Religious beliefs and involvement (referred to as religious involvement) included attendance at religious services, the perceived importance of religious beliefs, the influence of religious beliefs on life decisions, and sharing beliefs with friends. (5) Parental involvement included checking homework, helping with homework, assigning chores, limiting TV time, setting curfews on school nights, praising youth for their achievements, and expressing pride in their accomplishments. (6) Substance use prevention education (referred to as prevention education) included discussions with parents about the dangers of substance use, participation in substance prevention programs outside of school, exposure to alcohol/drug prevention messages outside of school, and participation in drug or alcohol education programs at school.

Other explanatory variables
Other explanatory variables included socio-demographics. Socio-demographics included high school grades (9th, 10th, 11th, and 12th grades), sex (male and female), race and ethnicity [non-Hispanic White (NHW), non-Hispanic Black (NHB), Hispanic, and others], English proficiency (very well/well vs. not well/not at all), health insurance coverage (yes vs. no), household poverty level (poor, near poor, above near poor), and family assistance, which included the use of food stamps, public assistance, or the need for welfare, job, or child care. Missing data handling varied; while high school grades, sex, and English proficiency data were not imputed, other sociodemographic variables included imputed values, as NSDUH prohibits missing responses to gender-related questions since 2002. A comprehensive description and interpretation of all the variables utilized in this study (not listed in Table 1) are provided in Supplemental Table 1.
Data analysis
Weighted percentages were calculated for each variable and the association of risk and protective factors with substance use outcomes were tested using the Rao-Scott Chi-square tests. Multivariable logistic regression analyses were performed to identify factors, particularly those in the six adolescent-specific domains, associated with alcohol, tobacco, and illicit drug use in the past year. Analyses adjusted for sociodemographic variables (sex, race and ethnicity, English proficiency, insurance status, household poverty level, and family assistance). Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) and p-values were reported. All analyses, including weighted replicates, were conducted using STATA 14.2 (College Station, TX).
Reporting guideline
This study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines (Von et al., 2007).
Results
From the initial 59,069 participants in the NSDUH 2022 dataset, we excluded 51,919 individuals who were not high school students (grades 9–12), 804 individuals who were not adolescents (aged outside the 12–17 range), 217 individuals who were not full-time students, 56 individuals with uncertain student status, and one individual who refused to disclose their student status. After these exclusions, the final study sample comprised 6,072 individuals, representing a weighted population of 13,131,547 US high school students. A detailed study flow diagram is provided in Figure 1.
Numbers and Weighted Percentages of Alcohol, Tobacco, and Illicit Drug Use by Risk and Protective Factors Among Full-Time High School Students (Aged 12–17 years) in the U.S. National Survey of Drug Use and Health (NSDUH) 2022.
Based on a total of 6,072 individuals included in this study. Individuals were divided into two group based on whether they used alcohol, tobacco, or illicit drug in the past 12 months (yes vs. no). Weighted percentages were calculated for each variable and compared using the Rao-Scott Chi-square test for categorical variables. Abbreviation: n, number; wt%, weighted percentage; NHW, non-Hispanic White; NHB, non-Hispanic Black.
Students exhibiting antisocial behaviors demonstrated significantly higher substance use across all categories, with usage rates of 32.1% versus 17.5% for alcohol, 28.4% versus 12.5% for tobacco, and 27.4% versus 10.2% for illicit drugs (all p < .001). In contrast, religious involvement emerged as a protective factor against the use of all substances (Table 2).

Discussion
This study found that the prevalence of substance uses among high school adolescents ranged from 18.0% to 23.5%, with alcohol being the most used substance. Two common factors, antisocial behavior and religious involvement, were identified as influencing substance use, including alcohol, tobacco, and illicit drugs. Specifically, antisocial behavior was a risk factor, as it was positively associated with substance use, while religious involvement was negatively associated. Identifying these factors can aid teachers, parents, and policymakers in implementing effective interventions to reduce substance use among high school adolescents. Reducing substance use is essential to prevent substance-related negative outcomes, minimize mental health disorders, and avoid the development of addictive behaviors, especially during adolescence. Our study focused on high school adolescents, a vulnerable population, and provides a comprehensive analysis of factors influencing substance use, contributing valuable insights that can guide future interventions.
Substance use trends in adolescents can sometimes predict future patterns in adults, as behaviors established in adolescence often continue into adulthood (Whyte et al., 2018). According to the 2022 SAMHSA report, nearly 50% of individuals aged 12 and older reported alcohol use in the past month, approximately 25% reported tobacco use, and 16% reported illicit drug use (Administration), 2023). The prevalence of substance uses among adolescents, 20–30% for alcohol, 10–15% for tobacco and marijuana, remains lower than that among adults (Administration), 2023; Volkow et al., 2021). Our findings align with these reports, with the lower prevalence among adolescents possibly reflecting the continuation of substance use patterns established in adolescence. This trend is further supported by the increasing prevalence of substance use as grade levels rise among high school students (Table 2).
Students exhibiting antisocial behavior were positively associated with substance use, which aligns with previous studies showing this association in adolescents using illicit drugs (Brennan et al., 2017; Trucco, 2020). Our study expands this association to include all types of substance use, including alcohol and tobacco. These findings emphasize the need for early intervention and appropriate support to guide adolescents toward healthier behaviors. Conversely, religious involvement served as protective factors against substance use (Fairclough et al., 2024). Many religions explicitly discourage substance use, viewing it as harmful to spiritual well-being (Grim & Grim, 2019). Adolescents who actively engage in religious communities may benefit from peer influence and strong social support, leading to lower substance use rates (Peviani et al., 2020).
Other factors associated with substance use in this study were also identified. Generally, males are more likely to engage in substance use than females (Rehm & Shield, 2019). However, recent trends suggest that this gap is narrowing, a shift observed among high school girls as well (McHugh et al., 2018). In our study, female adolescents were more likely to use substances than their male counterparts. One possible explanation is that adolescent girls may experience higher levels of stress, anxiety, and depression compared to boys, which can increase the likelihood of substance use (Esmaeelzadeh et al., 2018; Morken et al., 2023). Studies suggest that females may develop substance dependence more quickly than males, contributing to higher rates of use (Becker et al., 2017; Bobzean et al., 2014). Additionally, NHW adolescents had higher rates of alcohol use compared to other racial and ethnic groups, possibly influenced by parental attitudes. Research suggests that cultural norms and beliefs among NHWs may be more permissive regarding alcohol use, contributing to a higher rate of alcohol use (Sudhinaraset et al., 2016). Understanding these cultural and community differences is essential for designing targeted prevention and intervention strategies.
This study has several strengths. First, it focused on high school adolescents, a vulnerable population, providing a comprehensive analysis of their substance use, an area that is less frequently studied in literature. Second, it utilized a nationally representative dataset to examine substance use among high school adolescents, yielding results that align with other studies, further confirming the high prevalence of substance use in this population. Third, the study identified substance use trends from freshman to senior years, revealing a pattern that suggests potential substance dependency development during adolescence, highlighting the need for early interventions. Lastly, by identifying two key factors influencing adolescent substance use, the study can help guide the implementation of more effective strategies.
The study also has limitations. While we conducted a comprehensive analysis of the factors associated with substance use, including six specific domains, other potential influencing factors may not have been included, which could affect the study’s findings. Additionally, we categorized substances into three broad groups without identifying the specific substances used, which limits our ability to analyze individual product use or determine factors associated with each product. This study was limited to analyzing the prevalence of substance use and did not examine the impact or magnitude of its effects on adolescent populations.
Our findings suggest that different socio-economic factors, such as sex, race, ethnicity, and household poverty level, may influence substance use. Thus, future studies should include analyses that consider cultural and community-level factors or conduct sub-cohort analyses to further explore factors associated with substance use among high school adolescents.
Conclusion
One in three high school students reported alcohol, tobacco or illicit drug use. Alcohol was the most used. Antisocial behavior by students was a risk factor for substance use across all categories, while religious involvement served as a protective factor against substance use. These findings highlight the need for early and effective interventions to reduce substance use among high school adolescents.
