Hi and welcome to the planet.
all it takes is one cig and your hooked again especially at the begining.
so yes you have done the right thing especially when you have a kid around the house.
instead of always smelling like an ashtray you will have sweet odours of strawb,melon or whatever you are vaping. and the most important thing is its 95% safer than smoking and its been proved there is no risk of second hand vape.
there is so much kit out there now and quite a few are advertised as starter kits but they actually arent.
a few questions first.
how many cigs did you smaoke and for how many years and what brand. this will help us advise what nicotine strength you will need.
there are two main styles of vaping. mouth to lung just like smoking and direct to lung to blow massive clouds.
to give up i personally say mouth to lung is best. low wattage with high 12 or 18mg nicotine.
it will take 2-3 weeks to detox all the shite out of your lungs and the higher nic will help ween you off the cigs.
direct to lung is used at much higher wattage average 50-100watts but some tanks and coils can go upto 200watts. this is best with low nicotine like 3mg or a max 6mg. anything more and you will be coughing your guts up.
