Smoking And Psoriasis

Smoking has long been thought of as a risk factor for psoriasis. A new study published online by the American Journal of Epidemiology followed about 186,000 men and women for 12 to 20 years and found that current smokers had nearly double the risk of developing psoriasis, compared to those who had never smoked. In addition, past smokers' risk was 39% higher than that of non-smoking participants for developing psoriasis in the study.
