Analog Cigarettes – refers to regular tobacco cigarettes

Adapter – small piece that allows cartridges from one style of e-cig to fit onto another style of battery. The adapter lets users mix and match cartridge brands with the battery of their choice.

Atomizer – the electronic component in an e-cigarette that converts the nicotine solution into a vapor that the user inhales.

Automatic – a kind of e-cigarette that comes on when the user puffs on the device rather than requiring a button to be pushed in order to activate the e-cig. This is the most popular version of e-cigarettes that most closely resembles a tobacco cigarette.


Battery – the piece of the e-cigarette that provides power to activate the heating element. E-cig batteries are rechargeable unless you use a disposable e-cig.

Bridge – a tiny piece in the atomizer that is shaped like a U. It absorbs the nicotine solution and sends it to the heating element where it is converted into a vapor.


Cartomizer – the combination of a cartridge and a disposable atomizer.


Disposable E-Cigarette – an e-cig that is designed to be thrown away after all of the liquid inside the cartridge is used.

Drip Tip – an e-cig accessory with a larger opening to make it easier for the user to add new e-liquid into the atomizer. Drip tips can be used with atomizers or cartomizers.

Dripping – adding new liquid to the atomizer. The user adds a few drops of e-liquid to the bridge before vaping. Many e-cig users believe dripping creates better vapor because there is no filler material involved.

Dry Smoking – when the atomizer floods with solution. You should remove the mouthpiece and cartridge, then replace the mouthpiece and inhale. Use caution to avoid overheating the atomizer.


Electronic Cigar – works in the same way as an electronic cigarette, but gives the user the style and flavor experience of a cigar.

Electronic Cigarette – a battery powered cigarette which uses an atomizer to turn nicotine solution into an inhalable vapor. Eliminates smoke and tobacco as is used in analog cigarettes. Also called the e-cigarette, e-cig, and electric cigarette.

Electronic Cigarette Starter Kits – a complete kit that includes everything the smoker needs to begin using e-cigarettes. Most kits contain atomizers, batteries, chargers, cartridges, and a manual.

E-Juice – the liquid solution containing nicotine that is used in the e-cigarette.

E-Liquid – another phrase used for e-juice, as defined above.

E-Pipe – a personal vaporizer that looks like a pipe

E-Smoking – using an electronic cigarette


Flooding – when too much e-liquid enters the atomizer. Flooding results in a decrease in the amount of vapor and in the flavor.

FDA – The Federal Food and Drug Administration, a United States agency that regulates the food and tobacco industry.

Filler – absorbent material inside of the e-cig cartridge. Filler helps contain the juice within the cartridge so that it flows to the atomizer without flooding. Most filler is made from Polyfill.


LED – the light on the tip of the e-cigarette that comes on when the user inhales. The LED also gives the user information concerning the battery’s charge when it flashes or changes to green.

Leaking – when e-liquid comes out of the bottom of the atomizer and hits the battery, causing damage to the e-cig. This most often happens when the user adds to much e-liquid.

Low-Resistance – a low rated OHM level that sometimes causes the atomizer to heat quickly and produce vapor at a rapid pace. Often abbreviated as LR.


Manual – e-cigarettes that are activated with a button rather than coming on automatically when the user inhales. A manual e-cig usually has a button on the top or side which must be pressed to begin vaping. Some users prefer manual e-cigs because the seal protects from damage against leaks.

Milligrams – the measurement of nicotine found in e-liquid. Abbreviated as mg. Typical nicotine levels range from 0 mg to 48 mg. The medium nicotine content is 18 mg.

Mini-Cigarette – an e-cigarette that is smaller than the standard model. Mini E-cigs are comparable to the size of an analog cigarette.

Mod – an e-cigarette that has been modified from its original condition.

Mouthpiece – the piece where the e-cig user places his or her mouth to inhale


Personal Charging Case – Often abbreviated as PCC. A case that the user can take with them to charge e-cig batteries while away from an electric outlet. These are popular for e-cigs with lower battery life.

Personal Vaporizer – another name for the e-cigarette. Sometimes abbreviated as PV or used to refer to a modified e-cig.

Propylene Glycol – Abbreviated as PG, the liquid base used to create nicotine solution for electronic cigarettes.

Pen-Style – an electronic cigarette that looks like a ballpoint pen. Used for discreet e-smoking.


Smoke Juice – another term to refer to e-liquid.

Smokeless Cigarette – refers to an electronic cigarette, sometimes used as an alternate name to explain that the e-cig produces no smoke and only emits a harmless vapor.


Throat Hit – the feeling the vaper experiences when e-cigarette vapor hits the throat. Sometimes called a Throat Kick instead.

Topping – adding e-juice to the cartridge to be sure it is full. Sometimes called “Topping Off”.


Wick – a small piece of cotton inside the e-cig cartridge, holds the e-liquid


Vape – the act of using an e-cigarette; inhaling e-cig vapor

Vaper – a person who uses electronic cigarettes

Vaping – inhaling e-cigarette vapor

Vegetable Glycerine – used as an alternative to propylene glycol by people who make their own e-liquid. It is clear and odorless with a sweet base. Some believe it causes vapor production to increase.
