The Alarming Rise of Vaping Among South African Teens
A new landmark study has exposed a growing public health crisis in South African schools: widespread vaping among teenagers, with rates far exceeding those of traditional tobacco use. Conducted by researchers from the University of Cape Town (UCT) and published in The Lancet's eClinicalMedicine journal, the research surveyed over 25,000 high school students across 52 fee-paying schools in eight of South Africa's nine provinces. The findings paint a stark picture of nicotine addiction gripping the youth, challenging long-held perceptions that electronic cigarettes, or vapes, are a harmless alternative to smoking.
Vaping, which involves inhaling aerosolized vapor from e-cigarette devices, has surged in popularity due to flavored options, sleek designs, and aggressive marketing. In South Africa, where tobacco control measures have successfully curbed cigarette smoking, this shift represents a new frontier in youth substance use. The study's lead authors, including Samantha Filby and Professor Richard van Zyl-Smit from UCT's Department of Medicine, emphasize that without swift intervention, this trend could undo decades of progress in reducing adolescent tobacco-related harm.
Key Findings from the Largest Survey of Its Kind
The cross-sectional study, carried out between January and October 2023, utilized a mixed-methods approach combining quantitative surveys and qualitative responses to capture a comprehensive view of vaping behaviors. Out of 25,149 valid responses from grades 8 to 12, 16.83% (95% CI: 16.47–17.30) reported current vaping—defined as use in the past 30 days. This figure dwarfs other substance use: tobacco cigarettes at 2.08%, cannabis at 5.13%, and hookah at 3.16%.
Prevalence escalated sharply with grade level: 8.47% in grade 8 rising to 29.51% in grade 12, with some schools reporting up to 46%. Surprisingly, vaping was higher in lower-fee schools (19.49%) compared to high-fee ones (14.61%), indicating the issue transcends socioeconomic boundaries. Daily vaping stood at 38.34%, and over half of users vaped four or more days per week.
- Ever tried vaping: 36.71%
- Nicotine-containing vapes among users: 88.12%
- School variability: Mean 15.82%, ranging from 4.16% to 31.00%
These statistics underscore a normalized behavior in school environments, where devices are discreetly used during breaks or even hidden in classrooms. Read the full study in eClinicalMedicine.
Signs of Deep Nicotine Dependence
One of the study's most concerning revelations is the level of nicotine dependence. Nearly half (47%) of current vapers used their device within the first hour of waking—a classic marker of addiction. Additionally, 11.84% reported being unable to get through the school day without vaping, while 24.89% felt anxious or angry if delayed.
Researchers developed novel dependence scores (DS1 and DS2), revealing that 58-61% of vapers exhibited high dependence. Qualitative responses often downplayed addiction, with teens citing "enjoyment" or "stress relief," yet quantitative data told a different story. This discrepancy highlights adolescents' lack of self-awareness about their habits, complicating self-reporting.
Professor van Zyl-Smit noted, "The extent of use and dependence on nicotine is something researchers had never encountered with traditional cigarettes in the past." Samantha Filby added, "On our scoring system, 60% of the sampled adolescent vapers exhibit high vape dependence."
Health Risks: Beyond the Hype of 'Safer' Alternatives
While marketed as less harmful than cigarettes, vaping delivers nicotine—a highly addictive substance that disrupts adolescent brain development, affecting learning, memory, attention, and impulse control. In South Africa, where youth lung health is already strained by air pollution and respiratory infections, vaping exacerbates risks.
Short-term effects include wheezing, shortness of breath, and bronchitis-like symptoms. Long-term, flavored aerosols damage lung linings and blood vessels, increasing cardiovascular disease odds. Nicotine links to mental health issues: anxiety, depression, and high-risk behaviors. The study found continuation motives shifting from curiosity to coping with mental distress (27.6%) and addiction (16.2%).

What Drives Teens to Vape? Initiation vs. Persistence
Initial uptake stems from social influences (50.6%), curiosity (16.2%), and stress coping (19.6%). Flavors like mango and bubblegum lure experimentation. However, persistence pivots to enjoyment (33.1%), mental health management (27.6%), and addiction.
Co-educational schools showed higher rates, possibly due to peer dynamics. Stress and poor concentration weren't strong predictors, but individual inconsistencies suggest tailored interventions over blanket approaches.
Mental Health Connections and Hidden Struggles
Vaping intertwines with psychological distress. Teens report using it for anxiety relief, yet nicotine worsens it long-term. The study's mixed methods revealed teens minimizing dependence qualitatively while scoring high quantitatively—indicating denial or unawareness.
In SA's high-pressure school environment, with matric stress and socioeconomic challenges, vaping offers false solace. Filby urges, “Healthcare professionals should inquire about vape use during routine checkups.” Schools need counselors trained in addiction recognition.
Policy Gaps and the Pending Control Bill
South Africa's Tobacco Products and Electronic Delivery Systems Control Bill (B33-2022) aims to regulate vapes like tobacco: banning sales near schools, online ads, and flavored products. It introduces plain packaging and smoke-free zones, aligning with WHO frameworks.
Currently, vapes are unregulated, available via apps like Checkers Sixty60. The bill's delay fuels the crisis. Researchers call for its urgent passage: “Restrictions on vape marketing can aid in deglamourising vaping among our youth.” View the bill PDF.
School and Community Interventions
Punitive measures alone fail; education works better. Schools should integrate anti-vaping curricula from primary level, teaching addiction realities. Parental awareness campaigns highlight signs: fruity breath, vape devices disguised as pens.
- Debunk safety myths early
- Counseling for stress management
- Pharmacotherapy like nicotine replacement for addicted teens
- Peer-led programs
- Enforce no-vape zones

Stakeholder Perspectives and Broader Implications
Health experts like CANSA warn of lung injuries; educators report classroom disruptions. Parents express shock at accessibility. Economically, long-term costs from addiction and disease strain the health system.
The study, funded by Cambridge-Africa ALBORADA, fills African data voids, urging global action.
Path Forward: A Call to Collective Action
South Africa's teen vaping crisis demands urgency. Passing the Control Bill, school programs, and public campaigns can reverse trends. As Filby states, “We want to ignite action... shift public perception towards the reality that we do have a public health crisis.” With evidence now clear, stakeholders must prioritize youth lung and brain health for a healthier future.
