I started smoking due to depression and anxiety. They said smoking can help relieve stress. Little did I know, I have been smoking 2 packs a day. It went on for a couple of years. It felt heavy.. I had to be confined because of pneumonia. After recovering from pneumonia, i suffered from nicotine withdrawal. Insomnia and tingling in my hands were the worst. I was traumatized from smoking cigarette so I gave vaping a try. I’m continuing to observe the effects of this to my body. But right now, I got no problem with it. It has already been 7 months since I starting vaping.
