In a recent study in the journal Scientific Reports, researchers comprehensively evaluated the effects of heavy smoking across a range of oxidative stress, inflammatory, vascular dysfunction, and hematological biomarkers. They analyzed and compared bronchial biopsy samples and blood samples of male heavy smokers (n = 104) against their age and body mass index (BMI)-matched non-smoking counterparts (n = 94) in Erbil, Iraq.
Biomarker analyses revealed that heavy smokers…
