Every approved "smoking cessation" treatment product/method requires you to give up nicotine. We all know how difficult that can be. How easy did you find it to stop inhaling smoke when you took up use of e-cigarettes or another smoke-free alternative (e.g. snus, dissolvables.)
Someone has pointed out that there is no category for
"quit on purpose with no effort"
Work around: If you wanted to quit and just switched with no problem, select the second option. Think of going out and buying the equipment and charging up the battery as your "very little effort."
