As a child, if you have lived in a house where smoking was prevalent, chances of you becoming a smoker as an adult are nearly doubly high.

The findings are based on data from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), the largest ongoing study of this ethno-culturally diverse population in the US The researchers looked at data collected from 13,231 adults between the ages 18-74.
Forty percent of participants reported being exposed to smoking in their homes as children and adolescents, and 20% of all participants were current cigarette smokers. Childhood exposure to household smoking nearly doubled the risk of being a current smoker compared with those never exposed to smoking within the household.
The study was published online in the journal Preventive Medicine.
