Understanding Vaping

The term “vaping” pertains to inhaling and exhaling the aerosol, commonly called vapour, generated by an electronic device called an e-cigarette or vape. These devices heat a liquid mixture containing nicotine, flavourings, and other chemicals, transforming it into an inhalable aerosol. Unlike smoking, vaping does not entail tobacco combustion, leading some individuals to consider it a less detrimental alternative.

Vape devices, also known as e-cigarettes or vapes, come in various shapes and sizes. These devices generally comprise a rechargeable battery, a heating component, and a tank or cartridge designed to contain the vape liquid. The heating element, or coil, heats the liquid, causing it to vaporize, which the user inhales. Vape devices can range from small, discreet “pod” systems to larger, more advanced devices with customizable features.

Contents of Vape Liquids

The contents of vape liquids, also known as e-liquids or vape juice, play a crucial role in the overall vaping experience. These liquids typically consist of a combination of ingredients that create an inhalable aerosol when heated in a vape device. 

The main components found in vape liquids are:

  1. Propylene Glycol (PG)

Propylene glycol is a colourless, odourless liquid commonly used as a base for e-liquids. It is a synthetic substance with a slightly sweet taste used in various industries, including pharmaceuticals, food, and cosmetics. In e-liquids, PG produces a strong throat hit, similar to that experienced while smoking a traditional cigarette.

  1. Vegetable Glycerin (VG)

Vegetable glycerin is another base ingredient used in e-liquids, often in combination with propylene glycol. VG is a natural, plant-based substance derived from vegetable oils. It is thicker and has a sweeter taste compared to PG. VG is responsible for creating larger and denser vapour clouds in vape liquids.

  1. Nicotine

Nicotine is an optional but common ingredient in e-liquids. It is an addictive stimulant found in tobacco plants and can be extracted for use in vape liquids. Nicotine levels in e-liquids vary greatly, ranging from nicotine-free options to high concentrations. Some e-liquids use nicotine salts, allowing higher concentrations of nicotine to be absorbed more quickly into the bloodstream, providing a more potent and satisfying nicotine hit.

  1. Flavourings

Flavourings are added to e-liquids to create various tastes and aromas. These flavours range from tobacco and menthol to fruity, dessert-like, and exotic blends. Most e-liquid flavourings are food-grade and generally recognized as safe for consumption, although the long-term effects of inhaling these flavourings are not yet fully understood.

One of the dangers of vaping lies in the ultra-concentrated hit of nicotine that some vape devices deliver. Nicotine salts in some e-liquids allow higher nicotine concentrations to be absorbed more quickly into the bloodstream. It can lead to a stronger and more addictive nicotine hit than traditional cigarettes. Additionally, vape devices’ variety of flavours and discreet nature may encourage more frequent use, increasing the risk of nicotine addiction.

Vaping in the UK

According to the latest available data, there are approximately 3.6 million vapers in the UK, with the majority being current or former smokers. Since the introduction of e-cigarettes in the mid-2000s, this figure has risen significantly, primarily due to the growing belief that vaping is a safer substitute for conventional tobacco usage.

Vaping is more prevalent among younger age groups in the UK, with the highest percentage among adults aged 18-34. However, vaping is not limited to younger adults, as it is also used by older age groups seeking an alternative to tobacco or looking to quit smoking. A concerning trend is the increasing number of adolescents experimenting with vaping, which has raised alarms about the potential for nicotine addiction and long-term health consequences among this vulnerable population.

A decline in traditional smoking rates has accompanied the growing popularity of vaping in the UK. Many smokers have turned to e-cigarettes as a tool for smoking cessation or to reduce the harm associated with tobacco use. In recent years, Public Health England has endorsed e-cigarettes to help smokers quit, stating that vaping is significantly less harmful than smoking. However, concerns remain about the potential risks associated with long-term vaping and its effectiveness in helping smokers quit completely.
