"What’s behind this rise in lung cancer in women who have never smoked compared with men, and particularly in Asian American women? One possibility: While Chinese American women may never smoke themselves, they frequently live with partners or family members who do. (About 28% of Chinese American men smoke heavily, Dr. Li said.) “We think secondhand smoke might be one of the key risk factors, because they’re living with people who smoke,” Dr. Li said." [1]

I could see a possible scenario where a first generation (i.e. immigrant, English as a second language) Asian father/husband smoking at home in the 1990-2010 timeframe and not getting the second hand smoking messages/ads (that were primarily in English as quickly) as the rest of Americans and it's is just now that the statistics are showing up.
