Well after all this there is no nicotine intake from e-cigs maybe a simple test could draw more light onto this.. why not forum users pick up a test kit.. online they are $4 probably $10 in the stores..
this would only be accurate for people that only use e-cigs and everyone post there average usages and the test results
