ECIG = electronic cigarette; TPM = total particulate matter.
The profiles represent a typical tobacco cigarette smoker and experienced ECIG users using 4 s (“average”) or 8 s (“extreme”) puff durations and slow (17ml/s) and fast (33ml/s). Each profile was tested under two voltage conditions (3.3 and 5.2V). All conditions were tested using an 8.53-mg/ml nicotine concentration liquid. The average and extreme (slow) conditions were also tested using a 15.73-mg/ml nicotine concentration liquid.
