 The e-cig industry had a run-in recently with Girl Scouts of the USA and Tootsie Roll Industries over e-liquid flavors that taste like their respective cookies and candy. But while cease and desist letters may force those flavors off the market, vapors still have a ton of options. That's actually a big part of the appeal of vaporizers. Choice. We're not talking about the enjoy type e-cigs that look and taste like regular cigarettes. This is about more elaborate vaporizers that can be taken apart, modified, and accessorized to produce what those in the community call mods. First, there's the liquid. There are more than 1,500 companies making e-liquid in ever more creative flavors. Cinnamon toast crunch. Cinnamon red hots. Buttered popcorn. Bam! Dried bacon. Crab juice here folks. Mother's milk. Carrot cake. I can taste the frosting. And a cake. Some people mix their own varieties by combining liquid nicotine, artificial flavoring, and a base of propylene glycol or vegetable glycerin, all of which can be bought online. You can actually get the glycerin at Walmart because it's also used to make cake icing. Propylene glycol can be bought on Amazon, where it's advertised as an ingredient in shampoo. A warning. Adding alcohol to your e-liquid will not get you drunk. It will just make your throat hurt. Many vapors don't stop at plain chemistry, however. There's also the device itself, which consists of a battery, atomizer, and other hackable components. This may tamper with the atomizer to ensure a more satisfying puff or alter the heating coil to change the temperature of the vapor. These tweaks supposedly produce a better flavor and smoother drag. One popular goal is to make the cloud of vapor as big as possible. Some people will even use a reader to check the vaporizer's ohms, which will tell you how much power you can use without burning all the flavor out and permanently frying your vaporizer. e-cigs and e-cig liquid aren't regulated by the FDA, and modifying the devices at home carries risks. There have been more than a dozen documented cases of e-cigarette explosions in recent years, which makes the thought of messing with the battery a little scary. Meanwhile, e-liquid can also make you sick if it comes in contact with your skin, and please, please don't swallow it. Other than that, hack at it.
