Vaping FAQs

Vaping FAQs

We tend to get asked the same questions over and over – some are more advanced and technical queries; others are more generic questions about e-cigarettes that will resound with every person and company in the vaping industry.

  1. Are e-cigarettes safe to use?

In August 2015, Public Health England released a study that put all previous debates and confusion to rest. Their findings were that e-cigarettes are 95% healthier than smoking conventional cigarettes. They are now to be endorsed by the NHS on prescription as a way to help people quit smoking, after demonstrating to be as, if not more effective than nicotine patches and gum. Vaping in the media has been given a bad reputation due to a number of reasons – all of which have been techniques of scaremongering and have since been dismissed. 

  1. Do e-cigarettes contain anti-freeze?

No. Illustrating our point above, this myth was created by a 2009 FDA press statement regarding electronic cigarettes. The FDA tested 18 cartridges from 2 companies. Of those 18 cartridges, 1 tested positive for a non-toxic amount of diethylene glycol (approximately 1%). While diethylene glycol is occasionally used in anti-freeze, the chemical is not a standard ingredient in e-cigarette liquid and it has not been found in any other samples tested to date.

The base liquid for e-cigarette liquid is usually propylene glycol. Propylene glycol is considered GRAS (Generally Recognised As Safe) by the FDA and EPA. While it is also sometimes found in anti-freeze, it is actually added to make the anti-freeze less toxic and safer for small children and pets. Propylene glycol is a common ingredient found in many of the foods we eat, cosmetics we use and medications we take. It is also used in the fog machines used in theatres and night clubs. 

  1. Can e-cigarettes help me to quit smoking?

After the study from Public Health England was announced, the NHS stated that they were going to start selling e-cigs on prescription as a way to help quit smoking. Supporting this decision is a lot of real-world evidence and even some studies that strongly indicate that e-cigarettes are an effective alternative to smoking. Surveys show that up to 60% of e-cigarette users quit smoking traditional cigarettes while using e-cigarettes. One study showed e-cigarettes worked at least as well as the nicotine patch for nicotine replacement therapy.

  1. My battery doesn’t seem to be charging, what do I do? 

If your battery is not charging it may be due to a number of different factors. Firstly, ensure that the charger you are using is the correct charger for the battery. We recommend that you only purchase chargers from our website to ensure that they work correctly and safely. Next, make sure that you are charging the battery the correct way. Some batteries are charged via the top connection (510 charger), others such as the AQWA V3 are charged from the bottom via a micro USB. Mods that take external batteries require an external charger for the battery cells.

Sometimes the contact on the battery may be depressed due to over tightening – a simple fix for this is to raise the pin. Please see video link below:

  1. What are mechanical and non-mechanical mods?

Mechanicals Mods are in essence electronic cigarettes stripped to its ‘barebones’. These mods contain battery cells that when activated via a switch, complete a circuit that fires the atomiser/clearomiser which is attached to the mod. On the other hand, non-mechanical mods offer many more features such as variable voltage and/or wattage and have safety protection.


  1. Why should I buy a mechanical mod?

Mechanical mods are very versatile and are great to use with rebuildable atomizers (where you have to build your own coils and wick). For example, if you are building dual or quad coils, the resistance of the atomizer is often below 1ohms. On a non-mechanical mod this would not fire but on a mechanical mod it will. Mechanical mods are not aimed at new users, as they can be dangerous if used inappropriately. However, they are a must-have for an intermediate/advanced vaper.


   10. What is the lifespan of the atomiser and how do I tell it needs replacing?

‘Atomiser' refers to the atomiser head that is in all clearomisers and tanks. The atomiser head refers to the element, which is heated when the battery is activated and this is responsible for producing the vapour.

Typically, atomiser heads last for about two weeks but this is not the case all the time. As they are very fragile they can stop working after a few days if they are used excessively or if the voltage is too high. All atomisers have a Dead on Arrival warranty, this means that as soon as you receive the product you need to test it to see if it works, as soon as it works the warranty period ends. Atomiser heads are referred to as disposable goods and are not meant to last longer than a few weeks.

The majority, of clearomisers/tanks we sell are replaceable units; this means that the only part that needs to be changed within the unit is the atomiser head. You can tell if the atomiser head needs to be replaced when there is a significant lack of vapour or if you get a burning almost smokey taste.
