So is there truly a difference between natural and artificial flavorings? Yes. Artificial flavorings are simpler in composition and potentially safer because only safety-tested components are utilized. Another difference between natural and artificial flavorings is cost. The search for "natural" sources of chemicals often requires that a manufacturer go to great lengths to obtain a given chemical. Natural coconut flavorings, for example, depend on a chemical called massoya lactone. Massoya lactone comes from the bark of the Massoya tree, which grows in Malaysia. Collecting this natural chemical kills the tree because harvesters must remove the bark and extract it to obtain the lactone. Furthermore, the process is costly. This pure natural chemical is identical to the version made in an organic chemists laboratory, yet it is much more expensive than the synthetic alternative. Consumers pay a lot for natural flavorings. But these are in fact no better in quality, nor are they safer, than their cost-effective artificial counterparts."
I think also that natural sweet/fruit flavorings probably have some degree of natural sugars, whereas a synthetic of that flavor may not, and I think that may be the difference in vaping this particular "shisha strawberry" as opposed to some synthetic strawberry flavoring; this natural flavoring causes an EXTREME amount of coil and wick gunking, which just illustrates why natural flavors are not necessarily vape-friendly.
