<dons firefroof suit> I've thought a lot about this, too, and have formulated some half-baked, completely unscientific thoughts on the high level of tobacco use in Germany:
1) I am convinced one reason for higher tobacco usage is low brain serotonin levels ... more people in Germany are self-medicating for depression. Beer clearly helps, too.
2) There seems to be a baseline view that more favorable genetics (seriously ... I've heard people lumping it in with the lower AIDS incidence related to ancestors' Black Plague survival), lower body weight, a sensible diet and a modicum of daily exercise allow one to get away with a little bit of what one fancies. Outside of a few hard-cores, I have observed that daily consumption is probably <10 ... very few 80-a-day Kate Moss specials.
3) You-know-who was such a rabid anti-smoker that in the post-war era lots of people (notably women) jumped on the "let's make a complete break from the terrible past by lighting up in public" bandwagon. I also think that since it was so tightly rationed, it acquired panache as a luxury item.
4) Remember, cigarettes are a WWI-era American invention. People forget that everyone in the US smoked like truckers WWII through the 60s, and they all look great on photos because few were overweight. Of course, considering cigarettes only became mass-consumption items in the 1920s and mean lung cancer onset is at age 66, that means that 1966 would've been about the time that people would've started dropping like flies. Perhaps no coincidence that the US Surgeon General's report was 1964 ... it took that long for the epidemiology to show up. If cigarette smoking only became widespread in Germany in 1950, then the 66-year-old cohort would have been hitting the median point in 1996. Ergo, less collective consciousness/familial memories of grandparents/parents on oxygen in their final years.
5) They're cheap! Compare a pack of smokes in New York or London at c. EUR 8/pack to EUR 3-4 in Germany.
6) Medical, insurance and governmental authorities are much more accepting. I received a "rate your lifestyle" questionnaire from our
health insurance provider in which you only got an off-baseline score for tobacco use is you were >10/day! Plus, I think
life insurance companies might even grant similar-cost policies for for smokers and non-smokers [need a fact check on this]. My conspiracy theory is that they all know that smoking whacks people c. 10 years earlier than otherwise, which will keep the retirement/healthcare systems remotely solvent.
7) It's socially accepted to the degree that people are less stressed out about smoking themselves ... not the nervous pariah furtively sneaking a smoke behind the dumpster. Maybe the stress is as big a risk factor as those who happily puff away on few a day?
One clearly shoudn't smoke .. or live in Hong Kong, London or New York, or breathe German
Firmenwagenfeinstaub, either. I'm not a doctor, nor do I play one on TV.
