Many PSAs aim to stigmatize smokers rather than inform people of health risks of smoking. I’ve always hated New Zealand’s Not Our Future campaign for this reason. They’ve just started running some new ads. The message of one is a pretty clear: “If you smoke, you won’t get laid.” It seems to ask local two-bit celebrities (both male and female) whether they’d go out with a smoker. The responses are what you’d expect: “Hell no!” “It’s unattractive” “It stinks.”
They have a shitty site, so I can’t link to it directly, but you can watch it by going to videos (TV in lower left corner), adverts, advert 1. If anyone finds a linkable or embeddable version, please let me know in the comments.
