An electronic cigarette or e-cigarette make look like a typical cigarette, but it's actually an alternative to typical cigarettes containing tar and carbon monoxide. An electronic cigarette runs on a small battery and has a small cartridge filled with a liquid containing nicotine, as well as an atomizer which attaches to the battery. The atomizer heats the cigarette and turns the liquid into a vapor that's non-toxic. Smoking an e-cigarette might be a difficult transition to make, as the entire experience, while similar to smoking, isn't identical. The less you cough when you smoke e-cigarettes, the more enjoyable the experience will be.
Charge the battery of the e-cigarette before using it. A fully charged battery will produce the greatest amount of vapor and will make the entire experience more familiar, which is the optimum starting point when beginning to smoke e-cigarettes.
Select a cartridge flavor that you are used to. Many e-cigarette manufacturers produce a wide variety of cartridge flavors, from vanilla to cherry to mocha. If you're not used to these flavors but choose to smoke from an e-cigarette with such a cartridge, it could cause a coughing reaction. All e-cigarette manufacturers make a tobacco and menthol flavor, if that's what you're used to.
Select a level of nicotine in the cartridge that you are used to. For example, if you smoked ultra-light cigarettes in the past, select an ultra-light cartridge.
Take slow, shallow drags from your e-cigarette to acclimatize yourself to the taste and process. This will get your throat and lungs used to the experience and prevent you from coughing.
