Leading U.K. doctors urged the government Wednesday (August 28, 2024) to pass legislation to tackle “a vaping epidemic”, in particular among young people, by banning disposable e-cigarettes and all flavours apart from tobacco.

The call came alongside the publication of a British Medical Association (BMA) report which it said was a “blueprint” for the “bold actions needed”.

The previous Conservative government unveiled plans earlier this year to eventually phase out smoking, alongside banning disposable e-cigarettes and restricting their flavours and packaging.

The new Labour administration – which swept to power early last month – has revived the draft legislation but is yet to detail its exact approach.

The BMA report noted that vape use among children and young people has increased almost six-fold in the last decade.

It implored the government not to “shy away from taking brave action” in order to “stem the trend”.

“There is no denying we are living in a vaping epidemic,” Professor David Strain, chair of the BMA’s board of science, said in comments accompanying the report’s release.

He noted one in 10 ten adults now vape, while calling the six-fold increase in those aged between 11 and 17 who now vape “far more worrying”.

“As a doctor, I understand the role vapes can play in helping people to stop smoking, but they have no rightful place in our children and young people’s lives,” Mr. Strain added.

“An industry so obviously targeting children with colours, flavours and branding, to push a product that can lead to nicotine addiction and potential further harms cannot be allowed to happen any longer.”

The report recommends banning all disposable vape and non-tobacco flavour sales, as well as using imagery, colouring and branding on packaging and devices.

That would mirror current restrictions on cigarettes.

The BMA also wants curbs on advertising and marketing, and rules keeping vapes behind retail counters and not on display.

Meanwhile, it is recommending government education campaigns on the dangers of vapes to reduce their appeal, especially among youngsters.

“We are calling on ministers to take bold and brave actions that will make a real difference,” Penelope Toff, the BMA’s public health medicine committee head, said.

A Department of Health and Social Care spokesperson said marketing vapes to children and young people was “utterly unacceptable”.

The spokesperson said planned legislation will outlaw the practice while “regulating flavours, packaging, and changing how and where they are displayed in shops”.

While vapes or e-cigarettes first appeared around 20 years ago as an alternative to smoking, their prevalence and use have increasingly become problematic.

Governments and regulators are now catching up to what is widely seen as an addictive and unsafe product. Australia has just passed a world-first bill that will ban all vapes from general retail later this year.

Currently, the most predominant vapes on the market are single-use, disposable products designed to appeal to younger people. Despite their short lifespan, vapes are complex products that contain several valuable resources.

However, there are no practical means to collect or recycle vapes. Most end up as electronic waste or e-waste in landfill. Some are simply thrown on the street as litter. So what’s really inside vapes?

How do vapes work?

Vapes can be categorised as either reusable or disposable (single use), the more prevalent option.

Reusable vapes have a rechargeable battery and cartridge or liquid refills offered in a bewildering selection of flavours. More elaborate vapes contain microprocessors that offer customisable features, coloured LEDs and even small coloured screens.

In their simplest configuration, single-use disposables have the common components found in all e-cigarette types. Vapes contain a battery, a pressure sensor (like a modified microphone), an LED light, a heating element and a reservoir with e-liquid (the “juice”).

When the sensor is activated by taking a drag on the device, the battery provides power to a heating element that vaporises or atomises the liquid.

Tearing down a single-use vape

Analogous to the study of anatomy, teardowns are a technique used by industrial designers and design engineers to systematically disassemble a product.

This allows us to identify and describe the internal components and their relationships within a product. It can provide useful information about materials, manufacturing processes, assembly and technology.

Equally, it can provide insights into repairability, upgradability and ease of disassembly for end-of-life recovery for potentially valuable or harmful materials.

We obtained a random selection of commonly found, depleted, single-use vapes to teardown, identify and describe what is inside.

Housing

Disposable vapes are not designed to be disassembled. The main housing is made out of aluminium and covered in a paint finish and graphics, closed at the ends with plastic parts.

Once the housing end caps are removed, which is often not a straightforward task, the internal assembly slides out.

These internal parts are wedged or taped together within the main housing, and battery terminals are soldered to wires connecting to a pressure sensor and a heating element embedded in an e-liquid reservoir.

Battery

Despite disposable vapes being non-rechargeable, the ones we disassembled all contained a lithium battery. Although much smaller, they are not dissimilar to the bundles of batteries found in products like power drills and electric vehicles.

These cells have high-power density: they can store lots of electrical energy in a relatively small package. This is needed to supply periodic bursts of energy to the heating element, and to outlast the supply of e-liquid in the reservoir.

All the batteries we tested during the teardown of depleted single-use vapes still maintained a charge that could power a test light bulb for at least an hour.

Pressure sensor

An air pressure sensor is a semiconductor switching device. Not unlike a microphone that converts vibrations into electrical energy, the pressure sensor detects a drop in pressure and closes an electronic switch.

This occurs during the action of taking a drag on the vape, which creates a partial vacuum within the device. When the switch is closed, a simple (short) circuit illuminates an LED and supplies current to the heating element.

Heating element: vaporiser

The heating element is embedded in a cap at one end of the e-liquid reservoir and connected to a wick. When the device is activated, an electrical current heats a metal strip that vaporises some of the volatile e-liquid.

The e-liquid reservoir

Disposable vapes contain an absorbent foam material saturated with e-liquid and contained in a plastic tube with silicone endcaps.

In the centre of the reservoir is a wicking material that draws in the surrounding e-liquid to be in contact with the heating element.

The e-liquid itself contains a range of ingredients such as propylene glycol, nicotine and flavourings, many of them with unknown health impacts.

Designed for the dump

The consumption of vapes has been skyrocketing in recent years, and they now represent a significant proportion of an alarming new category of e-waste.

Single-use e-waste results in a significant loss of valuable materials – notably aluminium and lithium.

Worse, when a disposable vape is thrown in the bin, the energy-dense lithium batteries pose a fire danger for waste management workers.

The materials in vapes also have toxic effects on the environment when released.

Having potentially valuable metals mixed with other, low-value materials such as plastic makes vapes difficult to separate and recycle. Overall, single-use vapes are clearly wasteful of resources and dangerous in the environment.
