Where in the World Can I Vape?

What Does PG Mean?

Thursday, 21 April 2016  |  Admin

PG - you've probably heard it mentioned in vaping circles, but you might not know exactly what it is, and how it relates to vaping. And no, it doesn't mean you need your parents to accompany you every time you vape. PG is, as many of you know, an ingredient in e-liquid, and is one of the most important ingredients along with VG. Read on to get a more detailed idea of what's actually in the stuff you're vaping.

So, What's PG?

PG, or Propylene Glycol, is an organic compound. It is a colourless liquid which is almost odourless, but has a slightly sweet taste. PG has several uses outside of vaping, and can be found in asthma inhalers, medical products and beauty products, such as make-up, shampoo and baby wipes. It is also used in various edible items such as cofee-based drinks, sweeteners, ice cream, soda and dairy products. 

Is it Safe?

Studies have already found that PG is safe to ingest orally, at least, though most studies look at ingestion of PG rather than inhalation of it. A 2010 study looked at the effects of PGEs (a mixture of PG and glycol ethers), and found that they may cause an increased risk of respiratory and immune disorders in children such as asthma, hay fever and eczema. However, it was judged that the glycol ethers rather than the PG were most likely responsible for this.

PG in Vaping

Now that we've got the science out of the way, what about the actual experience of vaping PG, and what percentage to use in your e-liquid? Well, it depends on what your priorities are. A high proportion of PG leads to more of a 'throat hit'. This kick at the back of the throat is a feeling is something that smokers often crave, so if you're an ex or current smoker you might prefer more PG than VG, which has a smoother feel. PG also carries flavour better than VG, meaning there's a wider range of taste varieties you can enjoy. 

In terms of vapour, less is more with PG. It doesn't produce large clouds in the same way VG does, so if you want to 'stealth vape' and keep it inconspicuous in public then PG is definitely the way to go. 'Cloud chasing' is off the cards if you choose a high PG e-liquid, so those dreams of becoming a professional vaper will have to wait.

What Ratio Should I Use Then?

Well, this is going to depend on the individual and your priorities as mentioned above, but if you're new to vaping then a good suggestion would be to try a 50-50 ratio of PG to VG. If there's not enough of a throat hit, up the percentage of PG, and if it's too strong or the clouds aren't as big as you'd like, just lower the dose. One thing to remember, though, is that some set-ups are specialised for certain ratios so make sure you've researched this before you risk an unpleasant experience.
