Chemistry Class Meets Real Life: Analyzing the Contents of Vape Products

In the dynamic world of modern chemistry education, the integration of real-life applications into the curriculum is not just beneficial—it’s essential. One of the most intriguing and relevant topics for students today involves the analysis of vape products. This intersection of chemistry and contemporary issues offers a profound opportunity for educators to engage students with practical examples of how chemical analysis impacts public health, regulatory policies, and personal choices. As vaping continues to gain popularity, particularly among younger demographics, understanding the chemical composition of vape products becomes a crucial educational focus.

The Rise of Vaping and Public Health Concerns

Vaping, a practice that involves inhaling vapor produced by electronic cigarettes or similar devices, has surged in popularity over the past decade. Initially marketed as a safer alternative to traditional smoking, vape products have attracted a wide range of consumers, including those who’ve never smoked cigarettes. However, this rise has also sparked significant public health concerns, leading to a growing demand for thorough chemical analysis of these products.

The Chemistry Behind Vape Products

Vape products work by heating a liquid to generate an aerosol, commonly referred to as vapor, that users inhale. This liquid, often called vape juice or e-liquid, is where chemistry class can make a real-life impact. The primary components of most vape liquids include propylene glycol (PG), vegetable glycerin (VG), nicotine, and flavoring agents. PG and VG serve as the base of the liquid, with PG known for its ability to carry flavor and VG for creating denser vapor. Nicotine, extracted from tobacco or synthesized in a lab, is added in varying concentrations for those seeking its effects. The flavoring agents, which can number in the thousands, are what make vaping appealing to many users, offering a wide range of tastes from traditional tobacco to exotic fruits and desserts.

Analyzing these components in a chemistry class can teach students about organic compounds, solubility, boiling points, and the principles of aerosol science. By examining the specific chemicals used in flavorings, students can explore topics such as chemical synthesis, the structure-function relationship in molecules, and the safety implications of inhaling these compounds. This hands-on approach not only bolsters their chemistry knowledge but also instills a critical understanding of how substances interact with the human body.

The Role of Regulation and the Importance of Analysis

The regulatory landscape surrounding vape products is complex and varies by jurisdiction. In many regions, regulations focus on limiting access to minors, restricting certain flavors, and ensuring the safety of ingredients used in vape liquids. Herein lies the importance of chemical analysis. By identifying and quantifying the substances present in vape products, chemists can provide crucial data that informs regulatory decisions and public health recommendations. For instance, the discovery of vitamin E acetate as a harmful additive in some THC-containing vape products underscored the need for rigorous testing and regulation.

Students learning about these regulatory aspects can appreciate the vital role that chemistry plays in shaping policies that protect public health. They can also explore the ethical dimensions of chemical analysis, considering how their work might impact societal well-being.

The Controversial Ingredient: Nicotine

Within the vast array of substances found in vape products, nicotine stands out due to its addictive properties and health implications. While nicotine itself is not a carcinogen, its addictive nature can lead to dependence and increased exposure to other harmful chemicals through prolonged use of tobacco products or e-cigarettes. Analyzing nicotine content in vape liquids allows for a discussion on addiction, the biochemistry of nicotine’s effect on the human body, and the challenges of balancing harm reduction with the risk of addiction.

Real-Life Applications in the Classroom

Incorporating the analysis of vape products into the chemistry curriculum offers a multifaceted learning experience. Through practical laboratory exercises, students can engage in qualitative and quantitative analysis of vape eliquid, using techniques such as chromatography, mass spectrometry, and spectroscopy. These activities not only enhance their laboratory skills but also deepen their understanding of the principles behind these analytical methods.

Moreover, discussing the findings from these analyses in the context of public health, regulatory policies, and ethical considerations provides a comprehensive educational experience. It encourages students to think critically about the impact of chemistry on society and the environment, promoting a more holistic understanding of the subject.


The analysis of vape products presents an exemplary case of how chemistry class can intersect with real-life issues, offering valuable lessons in science, health, and ethics. By exploring the chemical composition of these products, students gain insights into the practical applications of chemistry and the importance of informed decision-making in matters of public health and personal well-being. This approach not only enriches the educational experience but also prepares students to navigate the complexities of modern life with scientific literacy and critical thinking skills.
