Before this turns into a thread war, which it probably will, let me assure you that
vaping is better than smoking. There is not conclusive proof of anything that was said in that article, on way or the other. What I can tell you is that other nicotine replacement therapies (patch, gum, inhaler(not ecigs, like asthma inhalers)) have a 90% failure rate after 6 months. That is, the users go back to smoking. Ecigs seem to be the opposite. They have probably around a 90% success rate. On top of that they are pure so they create an aversion to smoking, and smokers for that matter. If you vape for a couple months you will lol at smokers who you will pity.
Is nicotine safe to use all day every day? Is
vaping safe? The answer is very complicated. The consensus is that no one knows 100% for sure. Limited tests have been done on NRT (Nicotine Replacement Therapy) and most of it revolves around Snus (smokeless tobacco), Nicotine Patches, Nicotine Gum, and Nicotine Inhalers, and very little has been done on the ecigarette itself. Scientists can't even agree on what the absorption rate is of the nicotine you vape. Some say 10%, others 40%. What I can tell you with confidence is three things: it's MUCH safer than smoking which has 4000+ chemicals (43 of which are known carcinogens), nicotine levels were found to be very similar in the blood tests among smokers and vapers, and nothing is better than being free of all addictions. A nonsmoker/nonvaper is the healthiest you can be. One should eventually endeavor to wean themselves off of nicotine by decreasing their ejuice to 0mg of nicotine and quit when the physical dependence no longer exists.
Is Propylene Glycol dangerous to vape? It can be to some people. There is a very real chance that people can be allergic to it. The fact is, it is found in MANY of the products you use daily, from mouthwash, toothpaste, shampoo, conditioner, inhalers, and even personal lubricants. It has been used in the movie and theater industries in their fog machines for many decades and is considered by the FDA as GRAS (Generally Recognized As Safe). It's also found in food products. Some people point out that its flashpoint is lower than Vegetable Glycerin and that it produces the biocide Acrolein. The safe oral consumption rate of acrolein is 7.5 mg per kilogram (2.2 lbs) of body weight per day, according to the WHO (World Health Organization). That is many times more than you even vape in ml of
juice a day. So is it a threat? Not really.
They found diethylene glycol in one out of the 10 cartdridges they tested at random. So what? They found lead and melamine in our kids toys and baby formula but we still use those do we not? China sucks. They cut corners, but the people who got caught doing it didn't get fired, they were executed. Lesson to be learned here? Fearmongering is dumb, and don't live in China.
So before the battle ensues, know that a non-smoker non-vaper is the best thing you can be, but if you can't be one of those yet then being a vaper is far superior to being a smoker.
