New Study on Smoking and Psoriasis

More bad news for current and past smokers, a article in BBC News says Smokers have a higher risk of developing psoriasis, a study suggests. US researchers found that heavier smokers have a greater risk of the skin condition and this only falls back to normal 20 years after quitting. The study of 79,000 nurses published in the American Journal of Medicine also found that people with psoriasis who smoke had more severe disease. It is thought that toxins in cigarette smoke may affect parts of the immune system associated with psoriasis.
