I vaped 24mg for a long time before I transitioned down to 11mg. Whenever I'd feel a need to light up, I'd just vape heavy for a few minutes and it would go away. Remember, it takes a few minutes for vaping to produce the satisfaction. Tobacco smoke penetrates deep into the lungs. Vapor is mostly absorbed by the mucous membranes in your mouth and sinuses. Little of it gets very far out into the lungs. Tobacco smoke particles are tiny. Vapor mist is composed of droplets that are too large to enter the alveoli. Lots of the mist ends up wetting the bronchial tubes with little absorption.
If you want the most nic absorption, vape a mouthful and inhale it just enough to be able to slowly exhale through the nose. It's a noticeable difference you can feel. Heavy hits into the lungs produce nearly as much satisfaction as exposing it to the mucous membranes. If anything, you will begin to experience irritation in your lungs with thick clouds and high PG juice.
