GENERAL VAPING TERMS
Dry puff/burn/hit - If there is not enough e-liquid in the device, the remaining e-liquid may overheat causing a dry-puff. Almost all new vapers will experience this nasty phenomenon a few times in the early days, but it's easily avoided by ensuring sufficient e-liquid is present and coils are replaced often.
Lung Hit/Direct lung inhale - Alternative to mouth to lung hits, lung hits are inhales of vapour straight to the lungs.
Mouth to Lung hit (MTL) – Vapour is pulled into the mouth first and then inhaled into the lungs, Ie the same as when drawing smoke from a cigarette.
Throat hit - The sensation you get in the back of your throat when you vape (or smoke). You can increase the throat hit by adjusting the nicotine strength, PG/VG ratio and by the type of vape device you use.
Vape / Vaping - The e-cig version of 'to smoke,' the act of vaping.
Vapour - The steam-like vapour that is exhaled when vaping.
VAPING TERMS RELATED TO HARDWARE/EQUIPMENT/ACCESSORIES
510 Connector - The 510 connector is the industry standard threading type for connecting the top atomizer section of an e-cig to the bottom battery component.
Advanced Personal Vaporizer (APV) – An APV usually consists of a bigger battery and features such as variable voltage or variable wattage than a PV. Also referred to as a modified e-cig (MOD) or a third generation e-cigarette
Atomizer (aka Atty) - This is the top part of device that vapourizes the liquid creating the vapour that you inhale. It consists of a small heating element (usually a wire coil) as well as a wick to draw the liquid to the heating element. This component is central to the operation of any e-cig. The electrical resistance of the coil, the voltage output of the device, the quality of the wick, and the airflow of the atty all play significant roles in the quality and quantity of vapour produced.
Box Mod - A box mod is any APV that comes in a box shape, and are often times electronic variable-voltage or variable-wattage devices.
Cartomizer (or Carto) - This is a combination of a cartridge with a polyfill filling (which acts as the wick) and an atomizer. Both of these elements have been compressed in to a single piece that's easier to use and are typically disposable. Cartomizers are not known for producing robust flavor or an abundance of vapour but can be cheaper.
Cig-a-Like – An e-cig which very closely resembles a traditional cigarette in size and function. Also referred as a first generation e-cigarette because these were the first type of e-cigarettes to come out.
Clearomizer (or Clearo) - Somewhat similar to a cartomizer, a clearomizer has a clear or opaque plastic or glass tank, making it easy to see how much juice you have left in your vape. Also, clearomizers use a silica wick instead of polyfill filling.
Coil - The coil is the most important part of the atomizer. This is what the electricity from the battery runs through, subsequently heating the liquid on the wick to the point of vaporization.
Drip tip - Any mouthpiece accessory that you place on top of the atomizer.
Mod - A custom built, or modified Advanced Personal Vaporizer
O-ring - The small rubber rings that create an air-tight seal to prevent juice from leaking from an atomizer.
Personal Vaporizer (Abbreviated as PV) – Another name for an Electronic Cigarette.
Pass-through (aka PT) - This is a type of PV that plugs directly into a power source (usually some type of USB charger) and can be used while charging.
Priming - This involves dripping a few drops of e-liquid onto the cotton inside your coil to allow it to saturate with liquid. Each time you replace your coil, it's important to "prime" it and wait a few minutes before use. Be careful not to overfill.
RBA - Rebuildable Atomizer, a type of atty which has a tank or large juice well that does not require dripping liquid directly onto the wick.
RDA - Rebuildable Dripping Atomizer, a type of atty that does not use a tank, instead the juice is dripped directly from the bottle onto the wick.
RTA - Rebuildable Tank Atomizer, an atty that uses a tank reservoir to contain the juice.
Sub-ohm - This term refers to coils that are wrapped below 1.0 ohms and can produce a large amount of vapour. It is very important that you know what you are doing when wrapping a sub-ohm coil as it can over-stress your battery causing it to leak or worse.
Tank - A shorthand term for a rebuildable tank atomizer (RTA).
Vape Pen - An e-cig or personal vaporizer in the shape of a pen. A popular device for those first making the change from smoking to vaping. Also known as a second generation e-cigarette.
Variable voltage (VV) - Variable voltage devices allow you to control how many volts you're vaping at. This is usually controlled with a click-ring or button selector.
Variable wattage (VW) - Similar to variable voltage devices, but you control how many watts your devices pumps out while you use it.
Wick - The part of any atty that draws liquid from the juice well or tank up to the coil for vaporization. This component is usually made of organic cotton or silica. When you are vaping and start to get a bit of a burning taste to the vapor that usually means its time to replace the wick of your RDA, refill the tank of your RBA/RTA, or replace the cartridge of your cig-alike. Most wicks will last upwards of a week with normal use, but will eventually start to burn due to the heat of the coil.
Wire - Generally refers to the wire that is used to wrap coils for an atomizer.
VAPING TERMS RELATED TO E-LIQUID/NICOTINE
Acetyl Propionyl & Diacetyl are chemicals known as Diketones that are commonly found in the flavourings of many e-liquids. The concern around Diacetyl originated from popcorn factory workers who developed “popcorn lung” (an irreversible lung problem) found to be caused from inhaling high amounts of Diacetyl used to make buttered popcorn. Acetyl Propionyl is a substitute for Diacetyl and research suggests that it can contain or convert itself to Diacetyl. This chemical is considered a lung irritant and is potentially as harmful as Diacetyl. The levels of Diacetyl and Acetyl Propionyl found in e-liquids are many degrees less than what the popcorn factory workers were exposed to.
Doublers - are e-liquid bottles designed to make it easier for people to add nicotine to their e-liquid. These bottles come half filled, but the flavour is double concentrated (hence the name doubler).
mL - A measurement of volume applied to eLiquid products. The most common volumes available are 15ml and 30ml bottles, some companies also produce larger or smaller bottles.
mg - A measurement of the nicotine level in eLiquid. Most publicly available juices come in 0, 3, 6, 12, 18, and 24 milligram nicotine levels.
Nicotine - An alkaloid, psychoactive chemical in eLiquid. Caffeine is also a psychoactive chemical.
PG - Propylene Glycol, this substance is used as a base carrier for the nicotine and flavoring. Propylene Glycol has been deemed generally safe to be used in medical products as well as food products for general consumption. Some people have reported having an allergic reaction to PG. If you have issues with PG, it is suggested you look into using a product with a Vegetable Glycerin (VG) base.
Ratio - Usually used when referring to the PG/VG ratio of a specific eLiquid. Higher VG content produces bigger, denser clouds and is therefore favoured by the cloud chasing community.
Singlers - are simply a full bottle of e-juice which is ready to vape as it is.
Steeping - A term used by people that make their own e-juice to describe the act of letting newly mixed e-juice sit open to the air for a period of time to let the ingredients settle and the flavours to blend together.
Vapour production - A term typically associated with juices which indicates the amount of vapor produced during the typical use of an e-cigarette.
VG - Vegetable Glycerin, an alternative to Propylene Glycol which is sometimes used as the majority base in the E-Liquid. VG is what produces the clouds you exhale, the higher the VG content the more dense clouds you'll be able to blow. Vegetable Glycerin comes from the production of palm or coconut oils and is also used in sweeteners and in skin care products.
