It does sound like this worrying at a particular scene is what is driving him to the cigarettes. Perhaps some sort of relaxation therapy might help. something that will teach him to recognise the things he can do nothing about and stop fretting.

There is a saying by St Francis.. (not that I am religious)

Lord, grant me the serenity to accept the things I cannot change, courage to change the things I can, and the wisdom to know the difference.

It seems that perhaps he worries and works himself up about things he can do nothing about, so perhaps some sort of relaxation, anti stress type therapy would be of benefit. There are people on here who would know what might be suitable. Perhaps someone can advise.

Maybe Yoga or some sort of simple meditation, to soothe his restless mind?
