I put it in the same category as Ambien - works for most but OMG the dangers for the not so lucky few. Chantix's been under scrutiny by the FDA for a while and they gave it an escalated risk warning. One of my coworkers used it to stop smoking and he got the full run down, had to sign waivers, and said his wife was sleeping with one eye open for months I think littlerock's trying to ease her dad off the cigs so an e-cig might be easier than trying to convince him to take a drug for several months if he's not entirely committed to quitting. I've got my fingers crossed for her!!!
