I need some help.. I am trying to get a woman who has been smoking most of her life to switch to ecigs.. Right now she has a blu and doesn't like it.. She currently smokes new port lights.. Any good recommendations for a beginner and a juice that would work good for someone who smokes new port lights? She also seems sensitive to vapor.. Makes her cough.. Not sure if that is the PG or the VG. Any suggestions would be great
