The Effect of Flow Rate on a Third-Generation Sub-Ohm Tank Electronic Nicotine Delivery System-Comparison of CORESTa Flow Rates to More Realistic Flow Rates.

The text discusses a study on the effect of flow rate on nicotine yield in a third-generation electronic nicotine delivery system (ENDS) or electronic cigarette (EC). The study found that both power and flow rate significantly affect nicotine yield, with nicotine yield increasing with both higher power and higher puff flow rate. The findings suggest that using the current CORESTa flow rate of 1100 mL/min to evaluate third-generation ECs may underestimate nicotine yield and overestimate pyrolysis products, which could confound epidemiological studies seeking to link nicotine delivery to product satisfaction and acceptability.
