No surge in illicit cigarettes after implementation of menthol ban in Nova Scotia
Bibliographic record
Abstract
BACKGROUND: In May 2015, the Canadian province of Nova Scotia became the first jurisdiction in the world to ban menthol cigarettes specifically. The tobacco industry warned that 'the primary effect of this law will be to increase the illegal tobacco market in Nova Scotia'. This is the first attempt to examine the impact of the menthol ban on trends in illicit cigarettes. DATA AND METHODS: Data on the number of illicit cigarettes seized in Nova Scotia covering the period from 2007/2008 to 2017/2018 was obtained from the Provincial Tax Commission. Data from before and after the ban are compared. RESULTS: According to the local authorities, while the enforcement efforts in Nova Scotia have not declined, the number of seized illicit cigarettes declined significantly, from >60 000 cartons in 2007/2008 to <10 000 cartons in 2017/2018. Since the menthol ban, the seizure volume remained stable, with no statistically significant difference in the number of cigarettes seized before and after the menthol ban (t=-0.71, p=0.55). There were only a few small seizures of menthol cigarettes in the year following the ban, after which there have been no further seizures of menthol cigarettes. DISCUSSION: Contrary to the tobacco industry's assertions, there was no surge in illicit cigarettes after the 2015 ban on menthol cigarette sales in Nova Scotia. Credible, industry-independent evidence on illicit cigarette trade is desperately needed to support the implementation of tobacco control policies.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
