The below are a collection of some of the most common questions we get asked and a number of resources for more information about flavour concentrates and e-cigarettes in general.

Where do I get Started With e-Cigarettes?

Just 10 years ago, the term e-cigarette was practically non-existent. An e-cigarette is effectively a battery powered coil through which we pass an e-liquid (a.k.a.: e-juice, vape juice etc.) via a wicking system. When we heat the coil the e-liquid is vaporised and inhaled much like a traditional cigarette.

Today there are thousands of different components and options that can be considered if you are interested in starting to use an e-cigarette.

We suggest you take a look at our detailed blog posts here that will introduce you to some of the many different options available to you.

Will e-Cigarettes Help me Quit 'Traditional Cigarettes'?

In our opinion, use of e-cigarettes is not a good method in which to quit an addiction to cigarettes. While some people report success in using e-cigarettes to quit altogether, we feel that e-cigarettes are more of a replacement for traditional cigarettes than a method of quitting them.

The “benefit” of using an e-cigarette is simply that they are likely not as bad as traditional cigarettes. The inhalation of condensed vapour (and the drug Nicotine, if you are adding it) have been shown to be harmful to your health in recent studies, however it is a certainty that smoking traditional cigarettes, with their over 4,000 different ingredients and carcinogens is very harmful.

We suggest you have a look at any of the studies that have been conducted in relation to e-cigarette use, however the main limiting factor in many of these studies is that the long-term effect of using an e-cigarette is not known due to the products relatively short time in existence.

How do I Learn to Mix Flavours?

When starting out making your own flavours specifically for use in an e-cigarette there are a number of things you should consider.

You will need:

While the above is enough to get you started, it is important to note that these flavour concentrates must be mixed in suitable ratios. We suggest that for any new mix you start out with no more than 5% of the volume being flavour concentrate (i.e. in a 10ml bottle, no more than 0.5ml of flavour concentrate). Once you have tried the resulting mix you can adjust according to your taste.

A very helpful tool that we recommend are the calculators from These calculators will help you work out exacly what quantity of each ingrediant you need for your mix and the amount of nicotine you will need to add to get to your desired strength.

Where can I Find Flavour Recipes?

Starting out making your own flavours it is often helpful to see what others in the community have come up with. Some of our favourite locations for community developed recipes (and clones) can be found at:

There are also great resources to be found on the Reddit boards:


How do I Mix Nicotine Into my Juice?

Nicotine is a regulated drug in Australia and is Illegal to supply as part of a finished ready to vape juice.

All flavour concentrates and ‘ready to vape‘ flavours sold by Pro Flavours are free of nicotine.

Depending on your state’s local laws, you may be able to import your own concentrated nicotine for personal use and add it to either your own mixed flavours or our ‘ready to vape‘ flavours.

For competitive prices and usually quick shipping times, we recommend finding a New Zealand Supplier for your liquid nicotine, such as SoulBlu New Zealand.

PLEASE NOTE: Concentrated nicotine is very dangerous!! All precautions must be taken if you are handling this drug. Gloves must be worn as nicotine can be absorbed through the skin and careful consideration must be given to the amounts added to anything.

What is a Rebuildable Style Tank?

Rebuildable style tanks, commonly referred to as either:

RBA (ReBuildable Atomizer)

RDA (Rebuildable Dripping Atomizer)

RTA (Rebuildable Tank Atomizer)

RDTA (Rebuildable Dripping Tank Atomizer)

Are all types of atomizers that allow you to rebuild the coil and wicking sections using supplies such as these:

Some of the benefits to using a rebuildable style tank includes:

  • it costs much less than purchasing pre-made coils.
  • You have the freedom to easily change out your wick when you want to change flavours.
  • You have complete control over the power output and are able to create ‘sub-ohm’ coils for bigger cloud production.

We recommend you have a look at our detailed blog post on tanks if you wish to explore this further:


What is Propylene Glycol (PG)?

Propylene Glycol or “PG” is one of the main ingredients in most e-liquids, flavour concentrates and liquid nicotine.

PG is a synthetic organic compound that is used in both industrial and food applications. It is a viscous colourless liquid which is nearly odourless but possesses a faintly sweet taste.

There have been some studies on animals and humans as to the risks involved in inhaling PG vapour. We suggest you read the following summary of some of those studies here:

While some people can be allergic or sensitive to PG, the current studies available do not appear to conclude any major issues with the inhalation of PG vapour in the levels provided in typical e-juice.

Whilst we believe the above and the linked information to be true and correct, please do your own research and decide if inhaling PG vapour is appropriate for you. We also suggest consulting your doctor before you start vaping so that they can give you their opinion.

What is Vegetable Glycerine (VG)?

Vegetable Glycerin or “VG” is one of the main ingredients in most e-liquids and commonly makes up around 50%-70% of the overall volume of a pre-mixed e-juice.

VG is a colourless, odourless, viscous liquid that is sweet-tasting and non-toxic.

Most people feel that the more PG in a mix the bigger the ‘clouds’ or vapour that is generated.

Studies concerning the inhalation of VG vapour have been done since the 1940’s, including this one that states:

“The results of these experiments in conjunction with the absence of any observed ill effects in patients exposed to both triethylene glycol and propylene glycol vapors for months at a time, provide assurance that air containing these vapors in amounts up to the saturation point is completely harmless.”

These studies, however, would not have been done with the addition of flavour concentrates or even heating the liquids to the same temperature that is commonly seen in an e-cigarette which could change the results.

Whilst we believe the above and the linked information to be true and correct, please do your own research and decide if inhaling VG vapour is appropriate for you. We also suggest consulting your doctor before you start vaping so that they can give you their opinion.

What are Diacetyl, Acetoin & Acetyl Propionyl


Diacetyl was the first chemical that was found to possibly be harmful that was present in some e-juices.

Diacetyl used to be present in the manufacture of artificial flavours used on popcorn. When heated and inhaled second-hand by factory workers this could causes lung problems that are irreversible and was dubbed “popcorn lung”.

The Diacetyl amounts that were initially reported in many of the popular liquids are well above the safety limit that had been set by government safety organisations. Even the amounts shown as “trace amounts” in juices are well above the suggested exposure quantities. If possible, we recommend that you avoid e-juices of flavour concentrates that contain Diacetyl.

Acetoin and Acetyl Propionyl 

Acetoin and Acetyl Propionyl are the substitutes that have been used in flavour concentrates after Diacetyl began being removed by the flavour manufacturers.

Research suggests that these chemicals also can contain or convert themselves to Diacetyl.

These were initially used to be safer alternatives to Diacetyl, but they are still considered to be potentially harmful. These two chemicals are still considered lung irritants and their chemical composition is very similar to Diacetyl.

The above chemicals are commonly found in cream, coconut, vanilla, chocolate and other ‘dessert’ flavours. Please use your judgement and contact the manufacturer of any e-juice to acertain if they contain the above chemicals.

Whilst we believe the above and the linked information to be true and correct, please do your own research and decide if inhaling flavoured vapour is appropriate for you. We also suggest consulting your doctor before you start vaping so that they can give you their opinion.
