Thank you, I've been looking at something called a vim.If you want to replicate smoking then you want a mouth to lung set up ( MTL ) & 18mg of the flavour of your choice, this should need to be a 50/50 mix of PG/VG or 60/40. There are so many options to chose from. Nowadays pods are all the go to , even 20mg nic salts would be worth trying.
Have a look at pods and others will be along shortly, Personally I like the vaporesso podstick.
The most important first question really is:
Do you want to directly replicate the action of smoking?
Many do, but when I switched from smoking, I didn't.
