There are many models of e-cigarettes available. Some look like traditional cigarettes, others look similar to a pen and some even look like small flashlights. Some have LED lights, some have built-in liquid reservoirs, others have combined atomizer cartridges, some are tubular and some are even rectangular boxes. They come in all shapes and sizes and have different features for former smokers who wish to distance themselves from anything resembling a traditional cigarette or want a longer battery life and/or better performance.
The base liquid for e-cigarette liquid is usually propylene glycol. Propylene glycol is considered GRAS (Generally Recognized As Safe) by the FDA and EPA. While it is also sometimes found in anti-freeze, it is actually added to make the anti-freeze less toxic and safer for small children and pets. Propylene glycol is a common ingredient found in many of the foods we eat, cosmetics we use and medications we take. It is also used in the fog machines used in theaters and night clubs.
On April 25, 2011, FDA announced in a letter to stakeholders that it would not appeal the decision by the U.S. Court of Appeals for the D.C. Circuit in Sottera, Inc. v. Food & Drug Administration, stating that e-cigarettes and other products are not drugs/devices unless they are marketed for therapeutic purposes, but that products “made or derived from tobacco??? can be regulated as “tobacco products??? under the FD&C Act. The FDA stated that it is aware that certain products made or derived from tobacco, such as electronic cigarettes, are not currently subject to pre-market review requirements of the Family Smoking Prevention and Tobacco Control Act. It is developing a strategy to regulate this “emerging class of products” as tobacco products under the Family Smoking Prevention and Tobacco Control Act. Products that are marketed for therapeutic purposes will continue to be regulated as drugs and/or devices.
Contrary to some media reports and comments by legislators, regulation as a “tobacco product” under FSPTCA does not mean that e-cigarettes are automatically regulated in the exact same manner as tobacco cigarettes, ie., subject to PACT, flavoring prohibitions and indoor use bans nor subject to the same tax rates. However, it does mean sales of these products to minors are finally prohibited by law.
This is the most common question on e-cigarette forums. The best answer to that question is “none” and “it doesn’t matter.”
Since those considering e-cigarettes are usually seeking to replace tobacco cigarettes, they are under the assumption that having the most realistic, tobacco-flavored e-cigarette will bring the most satisfaction. The truth of it is that after switching to e-cigarettes for a few weeks, the vast majority of users discover that looks ultimately don’t matter – performance does. And the best performing e-cigarettes don’t necessarily look anything like traditional cigarettes because they require larger batteries. And the most popular flavors with experienced users are often as far from tobacco-tasting as one can get.
One problem is that none of the tobacco flavors really taste like burning tobacco – they taste more like fresh tobacco smells and slightly sweet. So, experienced e-cigarette users will tell you that nothing tastes exactly like a burning tobacco cigarette. But, we know you won’t believe us and insist on buying something that looks and tastes like a tobacco cigarette. That’s ok – we’ve all been there!

However, while some users have gradually reduced the nicotine levels down to zero, the majority of e-cigarette users treat the devices as an alternate source of nicotine and not as a nicotine cessation program. So there is not as much scientific evidence yet that show how effective e-cigarettes are when used to treat or cure nicotine addiction. Yet, anecdotal reports by users who have used e-cigarettes as a way to wean from nicotine also indicates they seem to be very effective way to break smoking triggers and dramatically reduce nicotine levels. As with pharmaceutical NRTs, it depends upon the smoker and the strength of his or her addiction and resolve to quit. E-cigarettes also appear to be a much safer option for short-term use in the event of relapse.
The good news is, nicotine by itself has very low health risks, so switching to e-cigarettes can be nearly as good as quitting altogether. The most important thing for those who cannot or will not quit nicotine to do is to stop the exposure to the harmful chemicals in cigarette smoke and e-cigarettes can help them do it.
