Higher cigarette pack-years related to smaller volumes in several subcortical regions. Magnetic resonance imaging studies of cigarette smoking-related effects on human brain structure have primarily employed voxel-based morphometry, and the most consistently reported finding was smaller volumes or lower density in anterior frontal regions and the insula. Much less is known about the effects of smoking on subcortical regions. We compared smokers and non-smokers on regional subcortical volumes, and predicted that smokers demonstrate greater age-related volume loss across subcortical regions than non-smokers. Non-smokers (n = 43) and smokers (n = 40), 22–70 years of age, completed a 4 T MRI study. Bilateral total subcortical lobar white matter (WM) and subcortical nuclei volumes were quantitated via FreeSurfer. In smokers, associations between smoking severity measures and subcortical volumes were examined. Smokers demonstrated greater age-related volume loss than non-smokers in the bilateral subcortical lobar WM, thalamus, and cerebellar cortex, as well as in the corpus callosum and subdivisions. In smokers, higher pack-years were associated with smaller volumes of the bilateral amygdala, nucleus accumbens, total corpus callosum and subcortical WM. Results provide novel evidence that chronic smoking in adults is associated with accelerated age-related volume loss in subcortical WM and GM nuclei. Greater cigarette quantity/exposure was related to smaller volumes in regions that also showed greater age-related volume loss in smokers.

Convenience store retailers should expect the next cigarette price increase to arrive sooner than the normal November cycle, according to a report by Wells Fargo Securities LLC. Wells Fargo conducted a survey of its tobacco retailer and wholesaler contacts representing approximately 60,000 U.S. convenience stores to gauge expectations for the next round of cigarette pricing increases. Bonnie Herzog, managing director – equity research, beverage, household & personal care, tobacco & c-stores for Wells Fargo noted, “According to our contacts, the next cigarette list price increase is expected to be led by PM USA during the week of Sept 18 at $0.08/pack (+2-3%). We agree as we don’t expect manufacturers to wait till the normal November cycle to take a price increase, especially given the severity of volume declines in Q2,” which were related to the outsized impact of California’s $2-per pack increase in excise tax. “As has been the case in past tax cycles, we expect the industry to further mitigate California tax-driven volume declines with list price increases, partially offset by stronger promo efforts. Longer term, we see further downside to combustible cigarette volumes if the U.S. Food and Drug Administration succeeds with its new nicotine mandate. However, we believe this could be mitigated by smokers potentially smoking more in an effort to get the nicotine levels they require—an ‘unintended consequence’—and increased conversion to reduced-risk products,” she added.
