NEW cheap vapes flooding the market are driving up waste levels and sparking concerns over the incoming ban on single-use vapes, campaigners have warned.

Campaign group Material Focus says “big puff” vapes, which are often rechargeable and hold up to 6,000 puffs compared to the usual 600, are becoming increasingly popular, particularly among 16- to 34-year-olds.

Representing better value for money, more people are turning to the devices, which campaigners warn may circumvent the new regulations set to come into force in June.
