As a nation, we have turned our backs on some of America’s most vulnerable workers. Right here, in Kentucky and other tobacco-producing states, children as young as 7 years old are facing Third World conditions. Toiling in the hot sun, these child workers must don black plastic trash bags with holes poked for their head and arms to avoid contact with tobacco leaves. Without it, their skin absorbs nicotine — a lot of nicotine. On a humid day, when tobacco leaves are dripping with dew, a tobacco worker may be exposed to levels of nicotine equivalent to smoking three dozen cigarettes. Nearly a two-pack-a-day habit.
