Hi:
I would say, especially if you have access to several of them, that working out some sort of program, using two (or at the most, three) of them at a time would be very beneficial.
"Smoke-free", while it deals mainly with quitting smoking, can be used to address the same sorts of issues as involved in addiction to cigarettes. New Behavior Generator and New History Generator would be helpful, especially if the addiction was the result of abuse in earlier life.
Generally, an addict cannot be "pushed" into doing something they do not want to do, so if you are writing on behalf of someone else, your first job (IF you decide to take it on) is to present this in such a way that it becomes "their" idea. Otherwise you are swatting at invisible flies.
Another suggestion would be to explore having at least a good talk with a local hypnotherapist - there is much that can be accomplished toward eliminating addictions in just a few short sessions with hypnosis - and THEN use the paraliminals (NBG in particular) - to assist in modifying behaviors related to the addiction.
Hope this helps.
Cheers!
