The evils of morphinism are even greater than those of alcoholism, and their transmission no less sure. Especially is there loss of moral power. Dr. Robertson says: "No matter how honorable, upright and conscientious a man's past life may have been, let him become thoroughly addicted to morphine, and I would not believe any statement he might make, either with reference to the use of the drug or on any other subject that concerned his habit. This extends further, and clouds his moral perceptions in all relations of life." 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.
