Is that in the plant or the fruit. Just asking.
We can do the math together.
According to Health New Zealand, a 16 mg. Ruyan e-cigarette delivers 0.053 mg of nicotine per puff, and 98% of that is absorbed, leaving 2% to be exhaled.
Source: http://www.healthnz.co.nz/2ndSafetyReport_9Apr08.pdf
0.02 * 0.053 mg = 0.00106 mg nicotine exhaled per puff
The nicotine contents of vegetables100g of eggplant contains 0.01mg of nicotine, and 10kg of eggplant is equivalent to one cigarette. However, absorbtion rates from ingestion are low and nicotine is quickly metabolised, so the effect isn't nearly the same.
100 grams = 3.52739619 ounces (which would be an average serving for eggplant)
0.01 mg nicotine in one eggplant serving divided by 0.00106 mg nicoitne per puff = 9.4339 puffs
So to equal the nicotine from one serving of eggplant, a bystander would need to lock lips with an e-cigarette user and inhale the entirety of 9.4 of their exhaled puffs. The amount of nicotine a bystander might be able to inhale from e-cigarette exhalations in the ambient air is probably miniscule to the point of disappearance.
The logical way to test this would be to recruit a volunteer and check their cotinine blood levels. Send them into a room with an e-cigarette user who is using 16 mg. liquid. Have the e-cigarette user take puffs at his or her usual pace and have the non-user count the number of puffs until a specified number is reached -- say 30 puffs?
Remeasure the cotinine blood levels of the non-user.
Good luck getting an Internal Review Board (IRB) to approve this experiment. They would claim that it exposes the non-user to too much potential danger.
Any scientific study involving human subjects that will be published in recognized scientific journal must have the design pre-approved by an IRB. Otherwise, you can conduct the experiment, but won't be able to have the results recognized as legitimate.
