Smoking is bad in that it is h.mp3ful to one's health. In spite of the fact that doctors have even warned
that it causes cancer, people still keep on smoking.
In some Western countries, however, people are beginning to kick the bad habit. They realize that health
should come first. To help them quit smoking, there are laws against cigarette advertising and smoking in
public places. This is praiseworthy except that Western countries are now selling cigarettes in the East
in greater numbers than ever. That they are doing this is immoral, don't you think?
