you are part right. the single most effective influence that results in
underage smoking is peer pressure.
the second most influencing factor is if your parent or parents smoked.
the flavors,the advertising have little if any effect. this has been proven
because when they eliminated flavors(6% of the market share excluding regular and menthol)
there was no reduction in usage in underage smokers.
the same with advertising.when advertising restrictions were
introduced our buddy Joe Camel had 30% market share in the
underage category. after the restrictions no decrease in cigrette
usage in the underage category.
so why the steady decline over the years? the message.
smoking is bad for you. i am not addressing if smoking was,
or is is bad as we have been led to believe. i am just
saying kids started believing it.
over time as less kids started smoking and more adults quit
or didn't start in the first place and we are right back to square one.
kids now days do not smoke because of (if you have been paying attention
you know the answer) peer pressure.(the antithesis of being cool)
the second most influencing factor,their parents don't smoke.
