To the Editor:
I write with reference to the paper by Stanley Schoenfeld and Philip C. Hoszberger entitled "Palatal Leukokeratosis Secondary to Candela pa Den" [Arch Derm 90:89 (July) 1964].In keeping with the exotic flavor of local dialects, I use the term from Southern India, "Adda Poga," meaning "reverse smoking." I wish to point out to the authors that this habit of smoking with the lit end inside the mouth has been reported in the literature:
Reddy, D. G.; Reddy, D. B.; and Rao, P. R.: Experimental Production of Cancer With Tobacco, Tar, and Heat, Cancer 13:263, 1960.
Reddy, D. G., and Rao, V. K.: Cancer of Palate in Costal Andhra Due to Smoking Cigars With Lit End Inside the Mouth, Indian J Med Science 11:791, 1957)
