Zakir Naik says,
Today we have come to know that tobacco in any form smoking chewing etc, is the second largest cause of death. The first largest cause of death of is alcoholism. Several billions [sic] of people die every year. It is the single leading cause of death. More than terrorism, more than war. Every year millions of people die. The second largest cause of death is tobacco. According to the World Health Organization, every year more than four million people only because of tobacco.
Let's assume his use of billions was a mistake, and address the content of the message. Is alcoholism generally worse than smoking on a global scale?
