My GI said it pretty much only helps ex-smokers.
Most GIs also tell us there is no benefit to diet change, but many of us here have had obvious benefits from altering our diets to some degree. They can't possibly know how any given med will affect any given individual, and they surely don't know how alternative treatments will affect each person either. We each have to weigh the risks/potential benefits and do some of our own experimenting.
I'm not a former smoker and am having great success with nicotine therapy. My GI is happy for me.
OP- hope your DH continues to feel well. And thanks for sharing.
