I have a 510 and a stick and they both irritate my lungs worse than cigarettes. I have been trying to do this, but it's like taking a huge b**g hit to vape versus having a regular analog which doesn't cause me to cough (as much). I am a 2 pack smoker. I don't get it, this is supposed to be more healthy but it's so much more punch to the lungs that I don't see how it can work. I have bad smokers cough from smoking. I was hoping to get rid of that, but this makes me cough MORE. What am I doing wrong? I normally inhale to the mouth and then into lungs. I have tried just directly breathing it in and it doesn't make a difference. I gack like a teenager. Any ideas? thanks.
