Collectively, these studies demonstrate that smokeless tobacco induces oral microbiome dysbiosis characterized by enrichment of pro-inflammatory taxa (e.g., Fusobacterium and Prevotella ), depletion of symbiotic species (e.g., Lactobacillus and Neisseria ), and activation of carcinogenesis-linked metabolic pathways (nitrogen metabolism and LPS biosynthesis), with dose-dependent effects and product-specific virulence

In Bray-Curtis distance-based PCoA of smokeless-tobacco-consuming and non-consuming healthy samples, PCo-1 explained 26% variation among healthy samples and significantly separated the two groups (PERMANOVA R 2 = 0.0634, p -value = 0.001, Figure 1D )
Effects on the Unborn Child Smoking during pregnancy increases the risk for: Low birth weight Premature birth, which in turn increases the risk for many other health problems Stillbirth Birth defects (women who smoke during pregnancy have lower levels of folate, a B vitamin that is important for preventing birth defects) Obesity and diabetes Cleft lip (a split lip that has not closed during the fetus' development) Some women have genes that may make them especially likely to deliver low-birth-weight infants if they smoke, although newborns of all female smokers are at greater risk for low birth weight
