I wasn’t aware that smoke creates a barrier that stops nicotine from absorbing. I would’ve thought that a larger dose of nicotine per puff and more often would allow a higher amount of free nicotine absorption per puff/amount of puffs. That’s interesting.For me, that’s not exactly true. The slower I smoke, the more time the nicotine has to absorb into the small blood vessels in my mouth and throat. The faster I smoke, the faster the smoke coats and prevents absorption. The slower, the more the smoke has time to work its magic.
