Over the past 12 months the council's Trading Standards team has seized more than 120,000 counterfeit or illicit cigarettes in the city.
The haul, which also includes 300kg of illegal hand rolling tobacco, was used to demonstrate the dangers of illegal tobacco as part of a roadshow in the city centre earlier today.
The cigarettes and tobacco will be destroyed in the coming weeks.
The roadshow raises awareness of the risks of illicit cigarettes and tobacco. Members of the public got to see a sniffer dog in action, demonstrating the skills used to help detect hidden tobacco when working with Trading Standards.
Councillor Diane Lamb, cabinet member for public health for Peterborough City Council, said: "Children and young smokers are often targeted by people who sell illegal cigarettes. All tobacco is harmful but cheaper illegal tobacco makes it easier for young people to start smoking and get hooked.
"Smoking remains one of the biggest risks to health and therefore free support to help you quit is available through the city's stop smoking service."
One to one support and advice is available from Peterborough City Council’s Stop Smoking Service. Call the freephone number 0800 376 56 55 to get an appointment with a specialist smokefree advisor at a range of locations in the city.
During October, the Healthy Peterborough campaign will be focused on ways to kick the habit and residents should visit the campaign's website for more information.
Councillor Irene Walsh, cabinet member for communities and environment capital, said: "People can make a real difference to help keep more illegal tobacco off the streets by reporting it. We'd encourage anyone who has any knowledge of suspected illegal tobacco sales to report it to Peterborough Trading Standards. Reports can be made anonymously.”
