Determining the proportion of illicit (contraband) cigarettes in a local
public health jurisdiction
Julie Stratton, Manager, EpidemiologyPeel Public Health
BackgroundSelf report surveys:
Most smokers buy their cigarettes legally
1% of Canadians might have purchased smuggled cigarettes (CTUMS)
13% of Canadians buy cigarettes from a First Nations reserve (23% of Ontarians)
Background Cigarette Butt StudiesCanadian Convenience Store Association
26% in Ontario youth (2008)38% in Peel youth (2008)
Ontario Convenience Store Association21% in Ontario residents (2014)22% in Brampton residents (2014)
Post-secondary campuses in Ontario – 14%
Peel Region• West of Toronto
• 1.3 million residents (20,000 people added each year)
•15% of Peel residents smoke
Research QuestionsWhat proportion of cigarettes in the
Region of Peel are illicit (untaxed?)
Are there differences in the proportion of illicit cigarettes by location of collection?
Methods – Sampling Frame4 types of locations within Peel Region
Regional hospitals (3 locations)Regional buildings serving the public (2 locations)
College campuses (2 locations) and university campus (1 location)
Secondary schools (random selection of 10 locations)
Methods – Pilot Study
Piloted process from one location from each venueCollectionIdentification
Methods – Sample SizeRequired 1,209 butts per venueParameters
Estimated number of cigarettes smoked per dayEstimated per cent of contraband based on pilot
studyAdjustment factor 1/0.7 - 1Precision of the estimate = 3%Statistical power = 80%Type 1 error rate = 5%Cigarette butt discard rate based on results of
pilot study
Methods – Collection and StorageHand collection from the ground or
dumped from cigarette disposal binsCollected butts until quota was metCollected on non-rainy daysStored in a fire proof cabinet in
plastic bins at an off-site location
Classification - TestingBrand name or symbolExistence of a dry patch within the

ConclusionLower percentage of contraband
cigarette butts than reported in other studies (5.3%)
The percentage of contraband cigarette butts varied by venue (highest in secondary schools)
Contraband rates are low - Peel will focus on other aspects of tobacco control
Implications for Public health practiceCollection of cigarette butts to assess
percentage of contraband cigarettes can easily be replicated in the field
Peel Health has developed the following protocols which can be shared:Cigarette Butt Study protocolCigarette Butt Collection ProtocolCigarette Butt Identification ProtocolCigarette Butt Photo Library
