What is caffeinated e-liquid?


Before delving into the pertinent questions about vaping caffeine, the important question to ask is, what is ‘caffeine vaping’?


Well, to put it simply, an illustration would be in order. Imagine getting that cup of coffee you drink every morning before going to work replaced by a vaping device with an e-juice that was produced from the same, or similar, ingredients used in the production of coffee. That, hopefully, does justice to the meaning of ‘caffeine vaping’.

Now, to the questions frequently asked about vaping caffeine.

How is caffeine vaping juice made?

Caffeine vapes are made to simulate coffee in such a way that it can replace the actual intake of coffee or any other majorly caffeinated drink. The condiments for producing caffeine vapes include a highly caffeinated Amazonian plant called guarana, ginseng and a supplement used in the production of energy drinks, called taurine. Various vape juice brands may however decide to approach the production of caffeine vapes from a different angle. Z-Fuel, for instance, incorporates hints of guava and orange in their caffeine flavours.

Each Z-Fuel 50ml Shorfill contains 300mg of caffeine per bottle of vape juice. 


Is it legal to sell e-liquid with caffeine in UK?

Every e-liquid that contains nicotine and sells in the UK and EU has to be approved by TPD ( TOBACCO PRODUCT DIRECTIVE) regulations. 


TPD regulations state that’s one cannot sell e-liquid that contains nicotine and caffeine together. However , if the e-liquid contains only caffeine (0% nicotine) can be sold quantities exceeding 10ml.


The production and labelling of electronic cigarettes and nicotine- containing liquids is controlled by the Tobacco and Related Products Regulations 2016.
Regulation 36(5)(a) prohibits such products from containing certain stimulant compounds
including, specifically, caffeine.
It is therefore illegal to produce or supply an e-liquid which contains both nicotine and caffeine. However, those Regulations only apply to e-liquids which contain nicotine. E-liquids with 0% nicotine content are instead regulated by the General Product Safety Regulations 2005. These


Regulations do not include an equivalent prohibition on the inclusion of caffeine. As such, it is lawful to produce and supply nicotine-free e-liquids containing caffeine as long as the safety of the product is not compromised by its presence and the product complies with all other applicable legal requirements.Further, as nicotine-free e-liquids fall outside the scope of the 2016 Regulations, the restriction on the maximum container size specified in Regulation 36(2) of those Regulations also does not apply. Therefore, e-liquids with 0% nicotine content (including those containing caffeine) may be sold in quantities exceeding 10ml.
