I offer to create special cigarettes using thermal paint and to apply a sign on the white part of the cigarette.
The sign might be as follows: The Ministry of Health DID alarm you and further several strokes where destructive substances would be indicated.

The fun is that at first sign it would be just a cigarette like one from the hundreds you smoke annually but the moment you light it the sign will gradually appear. Cool, isn't it?

Or time strokes can be marked with the help of thermal paint that would count time up to 5 minutes of your smoking. May be you can use it by gradually decreasing time of smoking
So...what do you think?
