Ik | Hygienic Laboratory as Washington, D.C, dune 20,1924, The Honorable George H.lMoses Chairman, Committee on Printing United States Sena tes Dear Sir: I am returning, under separate cover, the transcription of the testimony taken ot the hearing before the Committee on Printing of the Senate June 23,1924, My testimony has been corrected as requested. — There is submitted as additional evidence an article on drug addiction by AsGeDullez and meee which was pub« lished in Public Health Reports dated May 23,1924. There ig also submitted an editorial comment from tho Journal of fhe American Medical Association on this article and the one Mr,Richard ?.Hobson desires to have published, In reading over his article again, I find little in it that is accurate other than matters of commonplace knowledges The effect of the wholesale distribution of this pamphlet would be to spread misinformation, arouse unwarranted fears and excite curiosity. The fears wold produce many cases of unhappiness, nervousness and insanity, and the curiosity would produce some new cases of addiction. Sincerely yours, ' LKel | Lawrence Kolb, ! | Surgeon. USPHS
