The reason for this is that cigarettes are dry carbon based while ecig is water based. Your lungs balance the amount of moisture inside and when you take a puff from the ecig you have placed extra inside. The benifits of moisture is to allow you to cough the bad stuff out which is building in your lungs since regular ciggs dont help your lungs like ecig. cough I say and you will adjust to healthier lungs.
Thanks for that info! Problem is,,, I can’t handle even one puff! Will try again though.
