Hum - science or TC twististics? Kids addicted to nicotine in SHS?

I was interested in this study (below) only because I would love to blow it out of the water! Just the title shows the bias. I would like to have seen the questionnaires given to 9-12 year old never smokers. But, you have to pay! I bet the questionaires were suitably angled to achieve the correct answers - especially the ones on " 6% of never-smoking children reported symptoms of craving, 8% reported cue-triggered wanting to smoke, and 20% reported subjective symptoms in response to ETS exposure. In never-smoking children, a higher number of smokers in the child’s social environment was associated with more symptoms of cue-triggered wanting to smoke and more subjective symptoms in response to ETS."

Adults can't specifically analyse a "craving" - what is a "craving"? How do you ask about your "craving" without putting words in your mouth? Or drawing them out? 

This study makes me well suspicious of the "science" here.

 I grew up in a family where smoking, drinking and sex were frowned upon.  My sister and I smoked all our lives. A year ago I changed my brand to vaping, but my sister smokes still. So we grew up in a home where no one smoked, no relatives smoked and no friends of the family smoked. I was quite old before I saw anyone smoking. But I did spend the weekend sometimes with my granny and grandpa in their quarters at the YMCA and I loved the smell of cigarettes, pipes and cigars which I never saw being smoked as I was not allowed into any rooms besides their  living quarters. 

In comparison, all my five children grew up with both parents smoking, and in those days we smoked inside.  I smoked and drank through every pregnancy. All our children grew up healthy and well. Of five children, only my son smokes - five home rollies a day and he is wracked with guilt about that. Such guilt is very unhealthy - more unhealthy than smoking!

 So I don't know about this study below - sounds sort of Tobacco Control science to me. What do you think?

Responses to environmental smoking in never-smoking children: can symptoms of nicotine addiction develop in response to environmental tobacco smoke exposure?

 A recent line of studies has brought attention to the question whether repeated exposure to environmental tobacco smoke (ETS) is capable of producing psycho-physiological effects in non-smokers and whether symptoms of nicotine dependence can develop in the absence of active smoking. Children seem to be particularly vulnerable to the effects of ETS. We examined the occurrence of psycho-behavioural symptoms, designed to assess nicotine addiction and nicotine withdrawal, in a sample of 778 never-smoking children aged 9–12 years using cross-sectional survey data collected in 15 Dutch primary schools. In the present study, 6% of never-smoking children reported symptoms of craving, 8% reported cue-triggered wanting to smoke, and 20% reported subjective symptoms in response to ETS exposure. In never-smoking children, a higher number of smokers in the child’s social environment was associated with more symptoms of cue-triggered wanting to smoke and more subjective symptoms in response to ETS. Never-smoking children and children who had initiated smoking were equally likely to report subjective symptoms in response to ETS exposure. In conclusion, environmental smoking is associated with self-reported psycho-behavioural symptoms in never-smoking children. Future research needs to investigate whether symptoms in children exposed to ETS are physiologically based or whether they reflect other characteristics which predispose youth for smoking initiation in the future.
