I will be brief. Started smoking at 15 and continued for the next 25 years. Hit 40 and put the analogs down. Got introduced to e-cigs at 47 and have been enjoying ever since. The nicotine was never my concern. It was the thousands of toxic and deadly chemicals (all of which I am sure occur naturally) I wanted to get away from. Many of the beneficial properties of nicotine, when used in moderation, are ignored due to its connection with the use of analog tobacco products.
