I think the cigalike has a better success-rate, lol, and you don't require therapy or support-groups to go with it.... Unless you need a "buyers-group" to help you work through why you are paying $7-10 for a disposable, landfill-banned battery, and inferior e-liquids which support big-tobacco,
Chantix is horrible, but FDA approved because it has the backing of big-pharma lobbyists' dollars, and the tobacco industry knows it doesn't work (and has horrible side-effects), which is why they also support it!
