Choosing a nicotine level can be confusing. Vaping offers a variety of nicotine levels, including completely nicotine-free e-eliquid. Usually people chose a nicotine level based on how much they smoke or if they prefer filters, wides, lights, etc. Basically this means a higher level for heavier smokers and a lower level for lighter smokers. The truth is, most smokers have no idea how much nicotine their cigarettes deliver. Unfortunately this doesn't make choosing the right nicotine level in e-liquid any easier. That's why we've created a comprehensive guide to help you make an educated decision.
If you're trying to figure out how much nicotine is in your favorite brand of cigarettes you may find varying answers. A cigarette contains from 8 to 20 milligrams of nicotine on average. (But only about 1 milligram of nicotine is actually absorbed by the smoker. Cigarette smoking is a worldwide health crisis. It is linked to countless diseases and causes nearly six million deaths annually worldwide. But e-cigarette vapor doesn’t contain smoke. Therefore it doesn’t create the tar that causes the vast majority of the damage from regular cigarettes. The carbon monoxide and thousands of other chemicals created by the combustion process are what make smokers so prone to heart disease, cancer, and various lung conditions.. According to this research study "(...) smoking predicted cancer in this analysis and nicotine replacement therapy did not."
There is a huge difference between taking a puff on a 'mod' (higher powered advanced personal vaporizer) set at 20 watts or higher, and a tiny cigalike or pod device. The major variance is the amount of power output and the size of the coil, which equals more vapor (and more nicotine) per puff. Smaller devices usually produce less vapor, though this is changing as technology improves. With less vapor production a higher level of nicotine is required to satisfy cravings -- or the vapor must take many more puffs. High levels of nicotine are common with compact devices. More powerful devices produce more vapor. This means that the user inhales more nicotine per drag and needs fewer drags to get the same effect as smaller e-cigs. Low levels or zero nicotine are common with ”cloud-producing” devices.
Current scientific thinking tells us that an adult would have to ingest 500-1,000 mg of nicotine to reach a fatal dose. That doesn't sound like much, but with such low concentrations in vapor, it would be impossible to vape (or smoke) enough to overdose.
Nicotine overdoses are extremely rare -- and they always come from ingesting (drinking) or injecting into the blood stream. Before reaching a critical level the user would experience "nicotine sickness." The symptoms include nausea, racing heart, anxiety and clamminess. While incredibly unpleasant, none of these things are life-threatening to a healthy adult. All of them, however, serve as a warning to the user to stop their behavior. And, most importantly, nicotine cravings cease during this phase. The dangers of e-liquid are mostly to children, who may accidentally drink enough nicotine to become very sick, or even die. Vaping equipment, and nicotine-containing e-liquid should always be stored out of reach of children and pets.
Nicotine has a bad reputation because of its connection to smoking. But newer research suggests that nicotine by itself may be useful in reducing pain, stress, blood pressure, anxiety, and even possibly useful in treating Parkinson's and Alzheimer's patients. Smoking is a proven-deadly way to consume nicotine, and vaping doesn’t have more than a tiny fraction of the risk of inhaling burning plant material. But the ability to carefully control your nicotine intake is another reason vaping is a better choice.
