I am not a "full-time" vaper. I usually puff on an e-cigarette just a couple of times throughout the week. Because I am not addicted to nicotine, and don't want to ever go back on that route, I use e-cigarette cartomizers that don't have any nicotine in them (0mg). In the car There are times when I want to smoke, so I reach for my e-cigarette instead. Chicago isn't the most pleasant place to drive, so every once in a while, I'll grab an e-cig from my lavender carrying case, and after a few drags, the traffic doesn't seem that bad. When I started using them I wondered if anyone would give me weird looks. It turns out, other drivers never even noticed I was vaping. All eyes were on the road (good job guys). The most convenient way to vape in the car is a USB passthrough. I use an automatic because it's the easiest. At a restaurant Most smokers have a cigarette after eating. When I smoked, I had one after every meal. It made my stomach feel less full. Now when I go out to eat I will occasionally vape after eating. Since I don't really need to do it, I do take in consideration the company I'm with. Some of my friends seem slightly put off about it. They'll ask "Are you sure you can use that thing here?," and I'll tell them yes, it's fine. Pretty soon they get over it.
