How much tobacco plant/leaves is needed to extract X amount of nic?
[the answer may be known, but i do not know the answer]
I ask because i am guessing that extracting nic in a lab is far more efficient that extracting it in trillions of small fires being lit every hour the world over. Basically, even if big-smokie is profiting from nic extraction, are they profiting less because of efficiency? But then is that efficiency nulled by the inefficiency of vaping?
[yes the 'trillions' of cigarettes per hour was likely an exageration]
