Moreover, smoking can speed up the normal aging process of several tissues increasing the biological age. Changes in methylation due to smoking have been demonstrated at several loci across the genome, particularly in long-term smokers (Figure 1). The most consistent association reported in different populations has been decreased methylation in smokers in comparison with non-smokers at the CpG cg05575921, located in the gene for the aryl hydrocarbon receptor repressor (AHRR) located in chromosome 5
