Three out of every ten smokers are under the mistaken impression that cigarette butts are biodegradable, according to a recent study.

The research, which surveyed 1,000 smokers, found that 38 per cent have discarded a cigarette stub down a drain, with three in ten considering this an ‘appropriate’ method of disposal.

Over a third believed that disposing of them in drains would speed up the breakdown of the cigarettes. Key reasons for discarding cigarette ends in this manner include being in a hurry (23 per cent) or simply feeling that if everyone else does it, they might as well do the same (15 per cent).

The study was commissioned by Keep Britain Tidy, who are collaborating with a London pub to raise awareness about the issue of cigarette-related litter, after their data showed that hospitality venues see some of the highest volumes of discarded butts.

‘The White Swan’, located in Twickenham, is being renamed to ‘The Poisoned Swan’ to emphasise the impact that dropping cigarette butts down drains has on wildlife.

New patron, Johnny Vegas, commented: “It seems a lot of smokers don’t realise they’re doing more harm than good by disposing of their butts in drains. I was once fined for throwing my ciggie down a drain.”

Data from the environmental charity revealed that 47 per cent of smokers are unaware that dropping cigarette butts into drains can cause environmental damage as they end up in waterways, seas or on beaches.

Experts warn that cigarette butts are made of plastic and never break down. Research has revealed that a single cigarette end can pollute up to 1,000 litres of water, while the toxins can also be consumed by small animals, birds, and fish.

Allison Ogden-Newton OBE, Chief Executive of Keep Britain Tidy, said: “Cigarette butts are the country’s – and the world’s – most widespread litter problem with billions being thrown on the ground or dropped down drains every year.

“Our interventions have so far reduced cigarette litter in drains by 57 per cent, and we are thrilled that the White Swan and Johnny Vegas are joining us to educate, change behaviours and substantially reduce cigarette litter.”
