New research from Italy reveals that smoking cigarettes is linked to the development of psoriasis in adults.

The report found that the risk of developing psoriasis was higher in smokers than in those people who have never smoked, and this association was found to be particularly significant for women. Smoking more than 15 cigarettes a day was found to be linked with the development of pustular psoriatic lesions.
