Objectives:
We assessed the effect of the New York City (NYC) policy restricting sales of flavored non-cigarette tobacco products on retail sales using a quasi-experimental comparison design. We also studied possible cross-border purchasing and product substitution by consumers.
Methods:
We compiled retail scanner data for January 2010-January 2014 for NYC, a proximal comparison area (PCA) surrounding NYC, and the US. We used regression models to assess trends in sales of flavored cigars, smokeless tobacco (SLT), loose tobacco (RYO), and total cigars in all areas.
Results:
Sales of flavored cigars (-22.3%), SLT (-97.6%), and RYO (-42.5%) declined following policy implementation (all ps < .01). Flavored cigar sales declined nonsignificantly in the comparison areas. An average 7.4% reduction in total cigar sales was seen in NYC following the policy (p < .01), as cigar sales increased 12% nationally, suggesting that NYC consumers did not substitute flavored cigars with non-flavored varieties.
Conclusions:
Implementation of the NYC policy was associated with significant reductions in sales of all restricted products, both absolutely and relative to comparison areas. Despite persistent sales of flavored cigars, overall cigar sales in NYC declined following the policy, although more intensive enforcement is needed to ensure greater policy compliance.

Dot Product
In engineering, the dot product of any two vectors is the product of the magnitudes of the vectors and the cosine of the angle between them. It is denoted by a dot symbol between the two vectors.
Consider a vehicle pulling an object along the ground using a rope. If the rope makes an angle with the horizontal axis, the work done can be calculated using the dot product of the force applied and the object's displacement.
The dot...
Cross Product
The magnitude of the cross product is obtained by multiplying the magnitude of both the vectors and the sine of the angle between them. This means that a larger angle between the vectors will lead to a greater magnitude of the cross product.
