Other peer-reviewed studies provide support for these findings.[3] A 2018 study in Public Finance Review examined littered packs of cigarettes across 132 communities in 38 states, finding that 21 percent of packs did not have proper local stamps.[4] As noted by LaFaive and Nesbit, primary authors of the Mackinac Center study, smuggling comes in different forms: casual smuggling, where smaller quantities of cigarettes are purchased in one area and then transported for personal consumption, and commercial smuggling, which is large-scale criminal activity that can involve counterfeit state tax stamps, counterfeit versions of legitimate brands, hijacked trucks, or officials turning a blind eye.[5] The Mackinac Center has cited numerous examples over the many editions of this report, including stories of a Maryland police officer running illicit cigarettes while on duty, a Virginia man hiring a contract killer over a cigarette smuggling dispute, and prison guards caught smuggling cigarettes into prisons

A 2024 systematic review found some positive results (66.7% of studies reported positive impact), but methodological issues in those studies (small sample sizes, lack of biochemical validation, poor randomization) make it hard to draw firm conclusions
While this study found that sales of non-flavored versions of those products increased (5% for cigars, and 4% for pipe and RYO), it also found that teens in 2013 had lower odds of ever trying flavored tobacco products (37%) and or using any type of tobacco product (28%) compared to teens in 2010.50 Another study looking at scanner data both before and after the policy was in place found that sales of flavored tobacco products declined among several products (a 22.3% decline in flavored cigar sales, a 97.6% decline in flavored smokeless tobacco, and a 42.5% decline in flavored RYO)
