Article by Kenneth Quinnell at Crooks and Liars: Tobacco Laborers Denied  Basic Human Rights in the U.S. 

Includes this video:

Excerpt: "The report [by Oxfam and Farm Labor Organizing  Committee], 'A State of Fear,' shows that one in four tobacco farm workers  is paid less than the federal minimum wage. Many suffer from nicotine  poisoning after absorbing nicotine through their bare skin." Link to Oxfam report

An excellent comment: "I'll bet those workers only have  $400,000 after feeding their families and paying all their expenses, too.  What kind of life is that?"
