NewScientist's Short Sharp Science blog had a plug for this newly designed Smoking Jacket. Apparently, the idea is for conscientious puffers to blow smoke into their collars (instead of the air) to contain the smoke and curb second-hand ingestion. And while the wearable ashtray seems kind of stylish, and the idea's interesting (making a martyr of every nicotine-fiend on a smoke break, while displaying what smoking does to the lungs) it looks pretty irritating to clean.
