I think there is no need to explain how harmful smoking is; you all know that inhaling the smoke of the dreadful combustion of tobacco is the worst thing you can do to your lungs. This is where the fraction of the smoking population that turned to e-cigarettes benefits the most; instead of combusting tobacco, e-cigarettes burn e cig juice while giving you the same pleasure just without the negative effects of tobacco. If you have just started using an e-cigarettes, you should be familiar with some basic terms and principles.
Besides having a good clearomizer, you need to use quality e cig juice as well. There are 4 main ingredients an e juice contains: a base, that can be either PG (propylene glycol) or VG (vegetable glycerine), nicotine, flavours and water. The base is the most important ingredient of the e juice. It is the element that holds the nicotine and the flavours together in suspension so that the smoke-like vapor is produced. Both types of base are non-toxic organic compounds and safe for consumption.
PG, or propylene glycol is a far more popular base than the VG is. It is relatively thin in consistency and it is absorbed by the polyfill fabric inside the cartomizer a lot easier than the VG. It is a tasteless, odorless substance which means it will not mess with the flavours you add in your e cig juice. Also, the PG is a powerful humectant, which means it will dry your mouth and throat if you use it regularly. The down side of propylene glycol is that it may be allergenic to some users and cause mild allergic reactions, like a tingling sensation in the throat or serious irritations on some parts of the body. To prevent any of this, do not use the PG too often; make it a habit to switch to another base from time to time.
VG, or vegetable glycerin is the thicker base used in the e cig juice. This ingredient is a lot sweeter than the PG, so when used in combination with various flavours, the flavours are hard to detect. Plus, after using vegetable glycerin juices, some users experience phlegm building in their throat, as opposed to users of PG that experience dry throat and mouth. The thicker consistency that the VG juices have, allows the user to experience a lot more vapor and avoid allergic reactions since vegetable glycerin is not as allergenic as PG is.
The vaping community is divided on the question which base is better. Both have their advantages and disadvantages, so to make your choice a lot easier, look at things this way: if you are finding it hard to give up on tobacco cigarettes, go with PG in the beginning. This will closely mimic the experience of smoking. Afterward, when you get used to the PG, try VG, just to see if it is the right thing for you or not. And finally, you can always get a mixture from the two and get the best of both worlds; a decent throat hit and a pillowy clouds of thick vapor.
