Teen Vaping in NSW: What the Data Really Shows

The report “Turning the Tide on NSW Teen Vaping” from the Cancer Council NSW presents itself as evidence that Australia’s strict pharmacy-only vaping model is working and that youth vaping is declining. But when the data and methodology are examined closely, the conclusions are far less convincing than the headline claims suggest.

One of the first limitations is the methodology itself. The findings come from repeated cross-sectional online surveys of around 700 teenagers aged 14–17 in NSW per wave.  While surveys like this can provide useful snapshots, they are not designed to establish cause and effect. Because the respondents change between waves, the study cannot definitively say the decline in reported vaping was caused by the new pharmacy-only laws introduced in 2024. Many other factors could be influencing behaviour over that period.

The headline statistic in the report is that the proportion of teens who have ever used a vape declined from 29.6% in April 2024 to 20.1% in October 2025.  On the surface that sounds dramatic, but the way this figure is constructed is important. The “ever used” category includes teenagers who may have only taken “a few puffs” once in their life. In other words, much of the reported decline appears to be in experimentation, not regular use.

In fact, the report’s own data shows that frequent vaping among teenagers was already very low. By the final survey wave, only 2.6% reported vaping 100 or more times.  That raises an important question about the framing of the issue. If regular vaping is already rare among teens, presenting experimentation as evidence of a widespread crisis may exaggerate the scale of the problem.

Perhaps the most revealing finding in the report directly undermines the narrative that strict supply controls are working. Even after the introduction of the pharmacy-only system and bans on retail vape sales, most teens who had vaped still said it was easy or very easy to obtain vapes.  Although the percentage describing access as “very easy” declined somewhat, the majority continued to report relatively few barriers to getting them. This suggests that restricting legal access has not eliminated availability, but instead shifted supply to informal networks or illicit markets.

The findings on smoking are also notable. Despite the dramatic policy changes targeting vaping, teen smoking rates remained essentially unchanged across the survey waves.  If the policy goal is to protect youth health overall, the absence of any meaningful decline in smoking is significant. Public health policy must ultimately be judged by whether it reduces the most dangerous behaviour, which remains cigarette smoking.

The surveys show that while vaping experimentation changed over time, teen smoking remained essentially stable across the same period. The report itself states that smoking patterns among NSW teens were “largely stable” with no statistically significant change. 

If vaping were strongly acting as a gateway to smoking, you would expect to see smoking rates rise as vaping increased or fall sharply when vaping declined. But that’s not what the data shows. Instead:

Vaping experimentation fluctuated.

Smoking stayed very low and largely unchanged.

In other words, the report unintentionally undermines one of the most common claims used to justify strict vaping restrictions. It shows that even during a period when youth vaping was a major focus of public debate and policy intervention, there was no corresponding increase in youth smoking.

At minimum, the findings suggest the relationship between vaping and smoking is far more complex than the simple “gateway” narrative often presented in policy discussions.

Another important result concerns risk perception. The study found that large majorities of teenagers already believe vaping is harmful, with more than 80% agreeing that vaping can damage the lungs or harm the developing brain.  This is particularly interesting because it challenges a common assumption used to justify anti-vaping campaigns: that teenagers vape because they think it is harmless. According to the report’s own data, most teenagers already believe vaping is risky, yet some still experiment with it. This suggests that behaviour cannot be explained purely by lack of knowledge.

The policy recommendations at the end of the report also reveal its broader agenda. The authors call for stronger enforcement of the pharmacy-only system and suggest expanding tobacco licensing schemes to reduce the number of tobacco retailers.  In other words, the solution proposed is simply more restriction and tighter control, even though the data already shows that access remains easy despite existing bans.

This reflects a broader pattern in parts of tobacco control policy where supply-side restrictions are repeatedly intensified, even when evidence shows that consumers and markets adapt quickly. When demand exists, tighter restrictions often shift activity into unregulated or illicit channels rather than eliminating it.

The report also largely ignores the wider harm-reduction context. While it frames vaping exclusively as a youth problem, it does not meaningfully discuss the role that vaping can play for adult smokers attempting to move away from combustible cigarettes, which remain far more harmful. Treating vaping solely as a threat rather than part of a risk continuum oversimplifies the issue and risks distorting policy priorities.

Taken together, the findings tell a more complicated story than the report’s headline suggests. Experimentation among teens may have fluctuated, but regular use remains low, access remains easy, and smoking has not significantly declined. These are not the signs of a policy that has definitively “turned the tide.”

Instead, the report may illustrate the limits of a strategy built primarily on restriction, enforcement and messaging, without addressing the underlying dynamics of youth behaviour, nicotine demand, and illicit supply networks.

Declaring success based on modest shifts in survey responses risks overlooking the deeper question: whether the current policy framework is genuinely reducing harm or simply moving the problem into different spaces where it is harder to measure and regulate.
