id="article-body" class="row" section="article-body"> San Francisco-based e-cigarette company Juul makes headlines left and right due to its explosive surge in popularity (especially among teenagers) and market share.

Even after the company was forced to shutter its social media presence while the FDA investigated concerns that Juul was promoting underage use of tobacco products, iqos kibris Juul continues to prove popular with rising sales and affectionate nicknames, such as the "iPhone of vaporizers."

But what exactly is Juul, and is it safe to use one? Here are all the details you need to know about Juul.

What is it?
Juul is like many other e-cigarettes, iqos kibris but with a couple caveats that set it apart. First, this vape is sleek and hardly noticeable: It's USB-drive design can be enclosed in the palm of a hand, and it doesn't produce a massive plume of vapor like some other e-cigarettes. Second, the nicotine content in its cartridges or "pods" set a new precedent for the e-cigarette market.

E-cigarettes work by converting liquid nicotine into a vapor that the user inhales. They're battery operated and intend to provide a similar stimulus to that of smoking regular cigarettes.

Juul is small and discreet

One way the company encourages the switch from cigarettes to Juul is with their Juul calculator, where people can estimate how much money they'd save if they used a Juul instead.

How does Juul compare to other e-cigarettes?
Juul's high nicotine content used to be an anomaly in the e-cigarette market, but now researchers note it seems to be the rule. After Juul's surge in popularity, other e-cigarette manufacturers began bumping up the nicotine content in their products.

Juul uses a closed system, which means users can't refill the pods themselves, a helpful factor for quality control.  Some e-cigarettes, such as the Suorin Drop, use open systems that allow users to refill the vape themselves with bottles of e-liquid or e-juice.

Juul's small size, compact design and minimal plume make it more discreet than many other brands. With no buttons or switches -- just disposable, snap-on cartridges -- Juul is simple, and its built-in temperature regulation prevents you from experiencing a "dry hit." Dry hits occur when vape cartridges get too low on liquid or when they overheat, and produce a burnt taste and throat irritation.

The Washington Post/Getty What is in the liquid that the Juul turns to vapor?
The Juul comprises two parts. There's the e-cigarette itself, which contains the battery, temperature regulator and sensors that read the charge level. The pod contains Juul's patented e-liquid formula. A mixture of nicotine salts, glycerol, propylene glycol, benzoic acid and flavorings.


Glycerol serves as a humectant, which means it adds moisture to the solution. Glycerol is classified as "generally recognized as safe" by the FDA, so it's approved for consumption.

Propylene glycol is a synthetic compound commonly used in polyester production, but it's also approved as an additive for food, cosmetic and Heets cesitleri pharmaceutical products.

Benzoic acid occurs naturally in many plants, iqos ukrayna but its synthetic form is also widely used as a food additive and preservative. It's "generally recognized as safe" for those uses, but can be an environmental and health hazard in large quantities.

Flavorings is an ambiguous term, but most often refers to various natural and synthetic ingredients that companies use to flavor their products. For example, Juul doesn't specify what's in it's mint-flavored pod, but it probably contains peppermint extract or oil. 
The nicotine salts in Juul pods are a type of nicotine that supposedly feels more like a cigarette when inhaled, as opposed to other vapes that use freebase nicotine. Freebase nicotine, heets cesitleri which can cause coughing and leave a film in people's throats, is harsher and commonly used in cigars.
