Hi everyone. Just joined the forum and wanted to introduce myself. I am a 43 year old firefighter who has smoked since I was 17. I decided to try these electronic cigarettes, (21st Century), on a whim when I saw them at a local gas station. While not an exact replica of the cigars and cigarettes I am used to smoking, they have cut down on the amount I smoke by at least 50%. I found this forum and am currently researching what to get next. I like the simplicity of the prefilled cartridges but want to start experimenting with flavors. Any suggestions on what to start with?
