 | This is an essay. It contains the advice or opinions of one or more Wikipedia contributors. This page is not an encyclopedia article, nor is it one of Wikipedia's policies or guidelines, as it has not been thoroughly vetted by the community. Some essays represent widespread norms; others only represent minority viewpoints. |
 | This page in a nutshell: Smoking, or the use of other legal tobacco products, is not inherently important enough to mention and should not be included in biographical articles by default. |
The fact that a notable subject of a biographical article smokes cigarettes, or is attempting to quit smoking, should not be included in an article.
That a person's tobacco habit or vice is verifiable, even having multiple available citations, does not mean this detail is important enough for inclusion in a Wikipedia article. Tobacco use has no relevance to most biographical articles.
