Italian flavoring company FlavorArt posted an interesting snippet on its blog recently. Apparently, doctors in Italy encouraged a patient to quit smoking to relieve his idiopathic neutrophilia. The patient was unable to quit with traditional methods for several years. Finally the patient switched to ecigs and was able to get off cigarettes after just 10 days. Subsequent tests found his condition had cleared up.
If you're not sure what chronic idiopathic neutrophilia is, don't feel alone. I had to look it up in Wikipedia. The condition is a blood disorder that can lead to chronic infections of various types. Now you know, and knowing is half the battle!
