I know I’ve dealt with smoking before, but the problem persists.
Today’s invention is an ashtray which detects the presence of a cigarette and surreptitiously blows air through it in order to ‘smoke’ it faster. Ashtrays often have a directional niche into which the offending weed is placed, which makes puffing a stream of air directly at, and through, it much easier.
The smoke generated would be sucked into the body of the device and passed over some activated carbon. This would have the effect of reducing somewhat the damage which people do to themselves and others -if only by finding that they were mysteriously having to spend a great deal more, suddenly, to support their habit.
