Ernest S. Bishop, The narcotic drug problem (1920)
“ The idea that narcotic drug addiction should be accorded a basis of weakness of will—neurotic or otherwise, inherent or acquired—and should be classed as a morbid appetite, a vice, a depraved indulgence, a habit, has been generally unquestioned and the prevailing dogma for many years. It is very unfortunate that we have paid so little attention to material facts and have made so little effort to explain constant physical symptomatology on a basis of physical cause, and that there has not been a wider recognition and more general acceptation of scientific work that has been done. ”
