I am writing a term paper on smoking behavior among Latinos in the
U.S.  My teacher said that there is a good article by Stable in some
journal but he wasn't sure if that was the complete last name.  Can
you help me find this article?

This is probably the person your teacher meant:
Eliseo J. Pérez-Stable, MD 
Professor, Medicine, UCSF 
Program Member, UCSF Comprehensive Cancer Center, San Francisco
web page: http://cc.ucsf.edu/people/perez-stable_eliseo.html

If you look at his list of publications on the web page, there are a
number which deal with this topic.  However, the most comprehensive
one seems to be:
Pérez-Stable EJ, Ramirez A, Villareal R, Talavera GA, Trapido E,
Suarez L, Marti J, McAlister A. Cigarette smoking behavior among U.S.
Latinos: A National Survey. American Journal of Public Health 2001 in
press.

I went to the journal’s web site at http://www.ajph.org and searched
the archives for this paper, but it was not there (perhaps it has
still not yet been published – you could try contacting Prof Stable
through his web site to ask him for a preprint).   However, I did find
one on a very similar topic :
Eliseo J. Pérez-Stable, Amelie Ramirez, Roberto Villareal, Gregory A.
Talavera, Edward Trapido, Lucina Suarez, José Marti, and Alfred
McAlister
Cigarette Smoking Behavior Among US Latino Men and Women From
Different Countries of Origin
Am J Public Health 2001 91: 1424-1430

There were a number of other papers by Stable on the same theme in the
same journal.  If you go to http://www.ajph.org/search.dtl and search
on Stable in the author field and Latinos smoking in the keywords
field you can see them.  You can look at the abstracts (summaries) for
free, but it costs $7 to get access to the full text for 24 hours. 
You could try asking your library to help get you the articles for
free.

Search strategy on Google: Stable + smoking + Latinos

This is excellent.  Exactly what I was looking for.  Thank you.
