Disposable vapes will be banned in England starting in June under a government plan announced on Thursday, a move aimed at protecting young people’s health and reducing waste.

Single-use vapes, which are often sold in brightly colored packaging, have become the “product of choice for the majority of kids vaping today,” Andrew Gwynne, the minister for public health and prevention, said in a government statement.

An estimated five million disposable vapes are discarded each week in Britain, according to the government.

The proposed ban — which requires the approval of Parliament, where the governing Labour Party holds a large majority — would prevent plastic, lead and mercury from single-use vapes leaching into the environment, the government said.

It is also aimed at reducing problems caused by the disposal of lithium-ion batteries. Even when sent to recycling facilities, the government said, the products usually needed to be disassembled by hand, and the batteries posed a fire risk to workers in the waste industry.

“Single-use vapes are extremely wasteful and blight our towns and cities,” Mary Creagh, an environment minister, said in the statement, adding that the initiative was part of an effort to combat Britain’s “throwaway culture.”
