Dr. Brush says: "Cocaine is the only drug the effects of which are more dangerous and more slavish than the inhalation of the fumes of opium."
The danger in the fast life of this age is that we try to find something that will enable us to do our excessive undertakings with less feeling of fatigue. We fail to see in this that we are exhausting our reserve force, instead of adding to our store of force.
The Popular Science News says that kola, cocoa, chocolate, coffee, tea, and similar substances make nervous work seem lighter, because they call out the reserve fund which should be most sacredly preserved, and the result is nervous bankruptcy. Understanding that nervous bankruptcy of the parent threatens the welfare of future generations through the law of heredity, we will surely hesitate to bring ourselves under the strain produced by the use of these substances.
The most dangerous habit of the present would almost seem to be the tobacco habit, because it is considered quite respectable and is therefore almost universal. Men who are prominent, not only as statesmen and business men, but also as moral leaders, smoke with no apparent recognition of the evils, and lads can often sanction their beginning of the habit by the fact that a certain pastor or Sunday-school superintendent is a smoker.
But science has not been idle in regard to the investigation of the effects of tobacco, and the discoveries made have been published, so that we are not now ignorant of the tobacco heart, or tobacco throat, or tobacco nerves, nor of the transmission of nerve degeneracy to the children of smokers.
Girls sometimes think it is a great joke to smoke cigarettes for fun, and some grow into the habit of smoking, but the injury is not lessened by the fact that the use of the cigarette was begun in jest, nor that the user is a woman.
In fact, the Medical Times is quite inclined to assert that much of the neurasthenia, including a general disturbance of the digestive organs, now so common in that portion of the female sex who have ample means and leisure to indulge in any luxury agreeable to their taste, or which, for the time being, may contribute to their enjoyment, is due to narcotics.
During the Civil War we are told that 13 per cent. of all men examined were excluded as unfit for military service. We are now told that 31 per cent. are found to be unfit. Nearly one-third of the young men found physically incompetent to be soldiers! From what cause? Certainly tobacco must bear a large share of the blame.
Some years ago Major Houston, of the Naval School at Annapolis, made the statement that one-fifth of the boys who applied for admittance were rejected on account of heart disease, and that 90 per cent. of these had produced the heart difficulty by the use of tobacco.
Dr. Pidduch asserts that "the hysteria, the hypochondriasis, the consumption, the dwarfish deformities, the suffering lives and early deaths of the children of inveterate smokers, bear ample testimony to the feebleness of constitution which they have inherited."
