It can backfire. I forget the year and the country but some years ago there was an anti-smoking campaign, aimed at children, whose tag line was "Never say yes to a cigarette". Research then discovered that the words which stuck in the kids' minds were those at the end of the tag line, i.e. "Yes to a cigarette". The tag was subsequently changed to "Always say no to a cigarette"
