A vape shop owner says the long-term impact of the new disposable vape ban will be seen in years to come.
The ban on the sale of single-use disposable vapes was introduced on Sunday, aimed at protecting children's health and the environment.
Matt King, from Vapers Online in Street, Somerset, said he welcomes the ban and told the BBC he believes it has already started to make an impact.
"You're not seeing as many batteries on the street," he said. "In a year or so you're definitely going to see a big impact."
The new ban means that shops and supermarkets will no longer be able to sell disposable vapes but they can sell rechargeable or refillable devices.
While it is illegal to sell vapes to anyone under 18, disposable vapes, often sold in smaller, more colourful packaging have been cited as an important factor in the rise of youth vaping.
Currently one in seven 18 to 24-year-olds vape but have never smoked.
Mr King, who has worked in the vaping industry for around 20 years, said young people may be more likely to take up smoking due to the "smoother" experience vaping provides, compared to smoking.
However, he said he does not believe the colourful packaging is what has caused many young people to take up vaping.
"There's plenty of flashy packaging all over the place," he said.
"We see it in our supermarkets with alcohol, with everything."
Tara, who works in a Bristol vape shop, said: "When they first came out on the market, I felt like they were aimed at young children.
"All too often, I've seen young children with them, and trying to come into the shop to buy them as well.
"I actually had a parent come in here and ask for a box of disposable vapes for his child to take to school and sell. I've got kids of my own [and I thought] that's just disgusting."
