I am a 56 year old male that has smoked since the age of 15. I averaged a pack to a pack-and-a-half per day for most of that period. During that 40 years I tried many times to quit using pretty much every option known to man; hypnosis, patches, Chantix, group therapy…… Approximately 6 months ago I started playing with e-cigs. I started with the rechargables that look like a normal cigarette with disposable cartridges. Tried many different brands but finally settled on 21st Century Smoke. I went through what I called a transition period giving myself time to get use to the e-cigs. The main thing I learned during this period was that disposable cartridges can get pretty expensive, but I was able to totally quit the analog cigs while using them. Shortly after going 100% e-cigs, I started testing the refillable tank e-cigs. I started with a very bulky model that I purchased at my local mail, but found it a pain to carry around. I then switched to a pen-size model from E-Smart. Kept a good charge and the tank was sufficient to last most of the day. Been using that model ever since. The most difficult part of the whole thing was finding a fluid I could live with for the long haul. Tested many different brands, and finally settled on the Red and White brand from VaporKings.com. Actually I mix the Red and White with their Turkish blend, 2 to 1 respectively. Gives me the perfect flavor, and I’ve been on it ever since. Have now been a vaper/non-smoker for 4 months and 14 days. Could not have done it without the e-cigs. Health is great and have experienced no side-effects. Going back to analogs IS NOT AN OPTION, and not necessary as long as e-cigs are around. Tell the feds to keep their damn noses out of our business!!!
