Last night I attended an extended family celebration in a restaurant.
The temperature was below 3deg Celsius. (as indicated on the warning system of a Car.)
The dedicated smokers went to the smokers section only shielded from the elements by a thick plastic curtain. In the group were a smoking pair with 3 kids (6, 3 and a baby in a carry seat)
My proposal is roughly:-
Develop a nicotine rich fluid or gel that can release nicotine when exposed to air flow.
Manufacture dowel like imitation cigarettes and even paint the tip red and the base / filter.
There should be a chamber where the air could do its trick and release sufficient nicotine to satisfy the addiction.
The "smokers" can then attend the normal sections without being criminals.
While you are at it you may give the "smokers" a choice between lung and other cancers.
I don't want to have a share in the business (although a lot of money will be made) but I would be satisfied to receive the Tax savings.
