i have to say that the reason that i, 2,5 years ago, started vaping was plain and simple to save money while still getting my nicotine.
started out with the tiny cigalike batteries but they only lasted 2-3 hours before needing a recharge so i got some ego batteries and what a change that was... 12 hours batterie life pr charge and the same day the ego-t system got on sale i purchased it, the old system with some kind of wadding was ok, even tried some of the blue foam, but the taste of the tank system was so much better, and after getting the ego-t i was a happy vaper, and then the larger tank systems started to arrive and now its genesis attys that deliveres my nicotine and flavour cravings
so the cigarets can no longer tempt me as they just plain stink and taste like a crap
so im getting my nicotine and saving money (less after i got to know cookie)
but from my point of view you should get some stronger nicotine to start with ... some 14mg would be a good start and perhaps 18mg for your hubby, and then take it from there .... but if your british you get fast delivery so you can just order and have it next day... me over in mainland euro have to think ahead and order 5-10 days before i need it
personaly i started of on 14mg and havent lowered it as i dont see the need to stop getting my nicotine and i used to smoke 25-30 unfiltered stinkies
just a little mixed info there
now back to your topic ... benefits :
takes less then 3 days to get rid of the morning cough
takes less then 1 week to get your smell and taste back to where it actualy works
and in less then 3 weeks you can taste and smell everything (even ants farting in the garden)
in less then a week your cloths no longer smell like its been soaking in the ashtray
in less then a year you have saved 1000's of pounds that would have ended up in smokey nothing
VAPING RULES !
