It appears that the cocain addiction is, thus far, more a particular vice of the lower classes, but as such it seems to be spreading all over the world. According to Anglo-Indian papers it has become so prevalent among the street boys and school boys in Calcutta that the government has had to take the matter up with the idea of devising means for checking the evil. While as yet it is confined to the classes mentioned, it is feared that it will spread to others. In our own country it is particularly a vice of the Southern negro, and some states and municipalities have already legislation on the subject. The policy in India as regards opium has been thus far for revenue only, and it will be interesting to observe what will be done as regards cocain.
