Make an initial investment in a high-powered, 4-battery sub-ohm e-cig. And something like a TFV-12 tank. Get 24 mg nicotine juice. Turn it up to about 150-200 watts. Take a hit or two. Your head will be spinning from the massive nicotine rush like you never got from a cigarette. You'll have to sit down for a few minutes till you come to your senses and the dizziness subsides.
You could smoke a cigarette after doing that. But it would do
nothing for you, nicotine-wise. Not after taking that strong of a vape hit. Therefore, quitting cigarettes would be the easiest thing in the world. You'll never look back.
Nicotine, in and of itself, is not a carcinogen. Its no more dangerous than caffeine. Your lungs will immediately begin healing from all the smoke damage. And during this months-long process, you can vape to your heart's content and it won't interfere with your lungs healing at all.
