Effect of smoking cessation on plasma ascorbic acid concentration [PDF]
BMJ, 1996 Numerous studies have shown that cigarette smokers have a lower plasma concentration of ascorbic acid than non-smokers, but only a few have considered the antioxidant status of ex-smokers.1 We report the first controlled study monitoring the early effect of smoking cessation on the concentration of ascorbic acid in plasma.

Smoking and red blood cell phospholipid membrane fatty acids [PDF]
Prostaglandins, Leukotrienes and Essential Fatty Acids, 2016 Smoking is associated with lower n-3 long chain polyunsaturated fatty acids (LCPUFA) concentrations; however, limited studies have accounted for dietary PUFA intake or whether tobacco dose or smoking duration influences this association. We measured red blood cell phospholipid (RBC) membrane concentrations of fatty acids in 126 current smokers, 311 ...
