Why stockpiling vapes could be dangerous - as ban on disposables nears

A ban on disposable vapes comes into force tomorrow, with a warning issued about the "life-threatening dangers" of stockpiling.
From Sunday it will be illegal for any business to sell or supply, or have in their possession for sale, all single-use or disposable vapes.
Online nicotine retailer Haypp said 82% of the 369 customers they surveyed plan to bulk purchase the vapes before they are no longer available.
But the vapes contain lithium batteries and could catch fire if not stored correctly.
While more than a third (34%) of people surveyed by Haypp said they would consider buying an illegal vape after the ban, the overall number of people using disposable products has fallen from 30% to to 24% of vapers, according to Action on Smoking and Health.
Shops selling vapes are required to offer a "take back" service, where they accept vapes and vape parts that customers return for recycling - including single use products.
The Local Government Association (LGA) led the call for a ban two years ago, due to environmental and wellbeing concerns, and is warning people not to stockpile.
Cllr David Fothergill, chairman of the LGA's Community Wellbeing Board, said: "Failing to store disposable vapes correctly could cost lives, given the significant fire risk they pose."
How disposable vapes catch fire - or even explode
Figures obtained by the Electric Tobacconist, via Freedom of Information requests, found an increase in vape related fires - from 89 in 2020 to 399 in 2024.
Many disposable vapes use cheap, or even unregulated lithium-ion batteries, to keep the costs down. These batteries often lack proper safety features, like thermal cut offs, making them more prone to overheating and catching fire.
If the battery is damaged, or overheats in any way it can cause thermal runaway - a chain reaction where the battery's temperature rapidly increases, causing it to overheat uncontrollably.

Then, once these fires start start, they are very hard to stop. Water alone can make things worse if the battery is still generating heat, so they require specialised fire suppressants to put them out.
Batteries can then re-ignite hours, or even days later, making them a persistent hazard.
Disposable vapes are a hazard for waste and litter collection and cause fires in bin lorries, even though customers have been warned not to throw them away in household waste. They are almost impossible to recycle because they are designed as one unit so the batteries cannot be separated from plastic.
Some 8.2 million units were thrown away, or recycled incorrectly, every week prior to the ban.
The Department for Environment, Food and Rural Affairs (Defra) said usage among young vapers remained too high, and the ban would "put an end to their alarming rise in school playgrounds and the avalanche of rubbish flooding the nation's streets".
Circular economy minister Mary Creagh said: "For too long, single-use vapes have blighted our streets as litter and hooked our children on nicotine. That ends today.
"The government calls time on these nasty devices."
'One in five say they will return to cigarettes'
Separate research by life insurance experts at Confused.com found two in five people (37%) planned to stop vaping when the ban starts.
Nearly one in five (19%) said they would return to cigarettes once the ban comes into force.
The research was based on the answers of 500 UK adults who currently vape.
