Even a few cigarettes a day increases risk of rheumatoid arthritis

Number of cigarettes smoked a day and the number of years a person has smoked both increase the risk of rheumatoid arthritis, finds research in BioMed Central's open access journal Arthritis Research & Therapy. The risk decreases after giving up smoking but, compared to people who have never smoked, this risk is still elevated 15 years after giving up.
