What would you equate a pack of blacks(5 cigars) to in cigarettes?
There's way more nic content in cigars compared to cigs. Which, isn't meant to be inhaled in the first place. I would suggest 24mg to see if it's strong enough for you, if not then 36mg. It is a good idea to get 10ml of each (24 & 36mg) to see which one is best suited for you.
