I smoked to about 20 years 20 cigs per day. I tried many methods for quitting tobacco with no effects. Cold turkey, nicotine patches, medical therapy, hypnosis and Chanpix. Each method has its secondary effects. None of them works on me for a long period. My blood cholesterol and triglycerides was so high, my doctor recommend me to stop smoking. Also my wife got pregnant, I was worried about second hand smoke an the effects on my baby. I started vaping with disposables and then eGo style batteries. It was so easy for me to make the switch, It took w one day, it was like changing the brand of my cigs. I will never look barck. My blood tests normal, now. I am feelings better every day
