The researchers found that cigarette smoke and heated tobacco vapour were highly toxic to the cells both at lower and higher concentrations while e-cigarette vapour demonstrated toxicity mainly at higher concentrations.
What does higher concentrations mean?
I think for cigarettes they mean like Newport’s, marbloro reds are higher concentration/stronger. Than light cigarettes. While e cig it’s like you can get 3 mg vs 18 mg. Right??
I’m not sure actually
There’s nothing that identifies nicotine as the measure
