The Tobacco Products Directive 2014/14/EU (TPD) introduced new rules for nicotine-containing electronic cigarettes and refill containers (Article 20) from May 2016. MHRA is the competent authority for the notification scheme for e-cigarettes and refill containers in the UK and is responsible for implementing the majority of provisions under Article 20 The TPD introduced new rules which ensure:
• minimum standards for the safety and quality of all e-cigarettes and refill containers (otherwise known as e-liquids)
• that information is provided to consumers so that they can make informed choices
• an environment that protects children from starting to use these products.
There are various new requirements set out by the Tobacco Products Directive that will affect the consumer,
The new requirements are;
• restrict e-cigarette tanks to a capacity of no more than 2ml
• restrict the maximum volume of e-liquid for sale in one refill container to 10ml
• restrict e-liquids to a nicotine strength of no more than 20mg/ml
• require nicotine-containing products or their packaging to be child resistant and tamper evident
• ban certain ingredients including colorings, caffeine, and taurine
• include new labeling requirements and warnings • require all e-cigarettes and e-liquids be notified to MHRA before they can be sold
Electronic cigarettes are often known as e-cigarettes or vaporizers are battery powered devices are used to mimic the action of smoking combustible tobacco without production of the toxins found in tobacco smoke although often still containing the addictive substance nicotine.
This is a question the has been highlighted among skeptics of vaping and smokers looking into quitting or cutting down the amount of cigarettes they smoke, recently public health England (PHE) released a report stating "E-cigarettes are 95% safer than smoking”. Although there is no definitive answer to the question as of yet, we can be almost certain that vaping significantly reduces the health risks compared to smoking tobacco smoke due there being fewer chemicals inhaled into the lungs and is becoming the most successful and effective way for tobacco smoker to quit.
E-liquid is made up from four different main ingredients;
1: nicotine - which is the addictive substance also found in traditional cigarettes this is a crucial part of the e-liquid that satisfies ex-smokers addiction to the substance and comes in many strengths to help ex-smokers cut down on their dependence on the substance
2: Propylene Glycol (PG) - is also used in various edible items such as coffee-based drinks, liquid sweeteners, ice cream, whipped dairy products and soda.
3: Vegetable Glycerine (VG) - is a simple polyol (sugar alcohol) compound. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. Glycerol is sweet-tasting and generally considered non-toxic.
4: Flavourings - These are the component of E-liquid which tend to be more complex, some flavors use just one or two ingredients to create a distinct flavor, whilst others use several different ingredients to create multi-layered and sophisticated flavors.
An atomiser is the device used to store and burn e-liquid for the user to inhale, there are many different types of atomisers for example cartomizer or sub-tank all will house a coil made up from a relatively small gauge of wire often based on user preference that is used as the element to heat up the liquid saturated around the coil by a wicking material most commonly found are silica or cotton. The atomizer will be screwed on a device containing a battery which is used to heat the coil.
There are many different devices used to produce vapor,
Pen Style Reachable Device - Mostly pen style devices are made up of two parts, a battery used to power the device with a switch for turning the power on/off and for operating the device most often the same button and a atomiser screwed onto the top of the battery device and is used to store the device and also heat the e-liquid up using heating elements inside the device. These devices are often known as vape pens because the majority are relatively small compared to other vaping devices and are often about as long as a pen. These often are the deices most smokers start vaping on whilst cutting down or quitting smoking tobacco.
Box Mod or Advanced Personal Vaporizer (APV) - These devices are often used by the more experienced vaping community and are known to enhance the user experience of vaping by delivering more flavor and vapor. Most are variable voltage or temperature the e-liquid is vaporized at so the user can control their vaping experience and make it more personalized vape. They come in many different styles, sizes, colors and power outputs. Such devices often are powered by either replaceable batteries often from one to four depending on the device most commonly an 18650 battery or a built in litho battery pack.
Mechanical Mod (Mech Mods) - These devices are to be used by only experienced vapes that have good knowledge of Ohms law and battery safety as well as building coils. Mechanical mods are not regulated which mean a connection is made straight from the battery to the atomizer with no safety features and can cause serious damage if not fully understood but are known by vapers as one of the best devices for vapor and flavor production. They are a few different types of mechanical mods often revolving around the amount of batteries the device can handle for example a tube mod is the smallest but will only hold one battery unless stacked with an extension tube or a box mech mod which popularly house from two to four batteries more than often an 18650 battery, they can be house in the mod by either being in a parallel circuit or in series.
Maintaining your device can be a simple process and if done regularly will prolong the life of your device as well as helping maintain its performance and can be achieved by a few simple steps;
- Do not allow your device to get hot or overheat, taking small puffs of your device pausing in-between can help achieve this.
- Do not allow liquid in atomiser to run out, it will prevent the cotton inside the atomiser from burning and producing a burning taste when vaping.
- If batteries are removable charge them with an external charger this will also prolong the device's lifetime.
- Coils in atomisers should be changed every 2-4 weeks minimum.
- Keep your mouthpiece clean and clear Keep your battery terminal clean.
- Store Your E-Cig Right, away from direct sunlight and high temperatures, Upright and away from water.
- Store E-Liquid in a cool dry place away from direct sun light.
- Dont Screw your atomizer to tight only hand tighten
Use extreme caution when working with Li-ion cells, they are very sensitive to charging and if mishandled may explode or burn. Make sure the user has enough knowledge of Li-ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. Never continue to use an e-cigarette type device if you can feel the battery get hot. If your battery gets hot to the touch, or if it begins smelling: Do not use it anymore. Let it cool down in a safe environment preferably outside, and then dispose of correctly according to your local council guidelines, or make arrangements to return if under warranty. If your e-cigarette or device begins activating itself, immediately remove your atomizer and disconnect the battery. Do not trust the battery, or the atomizer anymore from this point on. This means never leave either of the components connected in your pocket, on your nightstand, or out of visibility where you can not immediately separate the two components.
You are allowed to take your e-cig device and e-liquid on a flight but you should check with individual travel providers before your journey and by following a couple of rules should ease your way through customs at your local airport, by putting your e-liquid into a clear plastic bag with other liquids and making sure they are in containers that hold no more than 100ml and also make sure there is no liquid in your atomiser. Devices should be carried on board as it is safer due to the cabin air pressure being at a normal rate this is not the same for the hold and could cause Li-on batteries to be damaged.
The difference mainly lies in the heating element inside the tank known as a coil in a regular tank the coils resistance will be 1 ohm or over, when heated it requires less power or wattage to produce vapor and produces less dense vapor. In a sub ohm tank the coil is under 1 ohm and produces a high-density vapour swell as more flavour these coils require a more power to heat up and burn through liquid faster therefore often have higher capacity tanks than the standard tank although under the TPD thanks cannot hold over 2ml of juice most manufacturers are producing extension kits separate to the tanks to comply with the regulations but also make it easy for vapers not to have to constantly be filling up their sub ohm tanks.
