I understand why the nicotine ones have an age limit, that is obvious.
Its just water vapor and it doesn't make any sense to have an age limit if it contains no nicotine.

Much love.

They're cheaper and yet again just water vapor so they have no smell and I could smoke them in my house. Why would I want to go to regular cigarettes? I smoke them when they are available but in no way am I addicted. Do you have a better answer?
