Cardiff Council's Cabinet Member for Environment says today's Usual Suspects campaign, launched today, has a stark message: you will be fined for dropping litter.
Cllr Ashley Govier told ITV Cymru Wales: "Cigarette ends and chewing gum are still something we consider 'nuisance litter' and quite problematic to the authority.
"We're trying to educate people - litter does cause an issue in the streets."
Cardiff Council said 14 people were issued with a £75 on-the-spot fine today - the first day of the crackdown.
