The real health risks of vaping

Vaping (also known as e-cigarettes or electronic cigarettes) might seem like a “safer” alternative to smoking, but evidence shows this isn’t the case. The number of young people who vape is increasing, in NSW about 1 in 10 (10%) of young adults aged 16-24 years were daily e-cigarette users in combined years 2022-2023. With the increase in vaping, there is also an increase in concerns about the serious health risks associated with it.

What is vaping?

Vaping involves inhaling an aerosol—often called vapour or mist—from a small, battery-powered device. The device, or “vape,” heats a liquid that usually contains nicotine, toxic chemicals, and flavourings. This vapour, packed with chemicals, is then drawn deep into the lungs, where it can cause a range of health issues.

What’s the harm?

At UNE Life, we’re committed to supporting students in making informed, healthy choices. Here’s a breakdown of the key risks as identified by Cancer Institute NSW:

• Toxic chemicals: Vapes contain hundreds of chemicals, including some you’d never expect to inhale. Formaldehyde (used in disinfectants) and acrolein (a weed killer ingredient) are just two cancer-causing chemicals found in e-cigarettes. The liquid in vapes may also contain ingredients that turn into harmful substances when heated.
• Lung damage and respiratory issues: Vaping has been linked to serious respiratory issues, including lung damage and increased breathlessness. While the long-term effects of vaping are still being studied, current evidence shows that vapes can be incredibly damaging to lung health.
• Nicotine addiction and poisoning: Many vapes contain nicotine—even products labelled as “nicotine-free” can contain it in small amounts. Nicotine in vapes is not only addictive but can also cause symptoms of nicotine poisoning, including dizziness, nausea, and even seizures.
• Physical harm and burns: Vapes can overheat and have been known to cause burns. This risk may seem rare, but it’s a serious safety concern that’s landed some people in the hospital.

Health risks in the short- and long-term

Here’s what vaping can mean for your health now and in the future:

• Short-term effects: Increased heart rate, respiratory irritation, and dizziness can all come from vaping, along with nicotine cravings that make it harder to quit.
• Long-term effects: The presence of cancer-causing chemicals and toxic ingredients means that vaping’s risks could include lung disease, heart disease, and various cancers.
