So you're wondering what to get your rabid anti-smoker for Christmas? How about a "mechanical smoker," which channels tars and nicotine onto a picture of the chest X-ray of a lung cancer victim? The stained pictures are collected in a protective bag that can be passed around the room for maximum effect. Only $29 plus $9 for a package of "minilung refill bags."

Or for anti-smokers who have tired of the ordinary "no smoking" signs, there are balloons proclaiming: "Will the real smokers please cough up!" and "Orphan Annie's Parents Smoked!"

For ex-tobacco chewers, there's "Mr. Gross Mouth, a hinged model of the teeth, tongue and oral cavity showing the effects of chewing tobacco." A bottle of tobacco juice comes with each model and instructions show how to make the tongue "spit."

These are among the items featured in a catalog most consumers may have missed -- Health Edco Inc.'s treasury of health education models and morals.

For those for whom the "just say no" words of anti-drug campaigns lack vividness, there is "needle vein," a blue latex vein with a removable blood clot; a life-size yellow "stained, shrunken" liver; or "snow nose" -- complete with damaged mucuous membranes -- for $69 each.

In "Smokey Sue Smokes for Two," smoke from a lighted cigarette flows through a lifelike model of a 7-month-old fetus suspended under water. As smoke bubbles to the surface, the tars and nicotine collect at the waterline. The $89 doll is designed to get the message across that "smoking mothers have up to a 10 times increased risk of miscarriage and their babies have three times the risk of birth defects."
