Non-smoker myself, but there are various people at work who have had great success with vaping - there is a small team of people at work who have all began vaping together - which is nice as it means they keep the social aspect of a cigarette break going for themselves, but also see the health benefits and encourage each other and obviously don't bring a god-awful smell back into the office with them.
I understand that there are several flavours you can purchase - anything from strawberry to whisky?!
