Does it matter where my e-liquids come from?

It shouldn’t as all products should meet the same safety standards, but be aware there will be exceptions as not all will have the same high level quality procedures and safety compliance, particularly of those associated manufacturers in Europe or North America. Another consideration is on whether you are purchasing an e-liquid with nicotine already mixed in or a zero-nicotine e-liquid. A liquid with nicotine pre-mixed will have had to have provided a significant amount of data in the registration process, where as zero-nicotine (or short-fills) e-liquids can be less regulated at this point. I’d suggest purchasing pre-mixed e-liquids and check for an ECID number which is used to register the product in the EU.
