First and new-generation e-cig devices
There was a study done where nicotine absorption from first and new-generation e-cigs devices were compared. The resuts shows that new generation devices that have higher wattage output resulted in higher plasma nicotine levels than first generations devices. Both devices were compared to tabacco cigarette and both delivered to the bloodstream far lower nicotine. The conclusion is that from the time when first e-cig devices where invented we’ve done big steps. The future of e-cigs is bright and the quality of e-cigs are going to be better and better.
