There are many common questions when it comes to e-liquid. Whether you are curious about our most popular flavors, ingredients, storage, or return policies, we hope to answer any questions with our e-liquid FAQ.

How safe is vaping? Can I quit smoking by vaping?

Public Health England (PHE) concludes that e-cigarettes are significantly less harmful to health than tobacco and have the potential to help smokers quit smoking. E-cigarettes are around 95% less harmful than smoking. Learn more about vaping's impact on public life

What is PG and VG?

VG is Vegetable Glycerol, a safe food additive used in most of the food and also naturally exists in most of the organic food. It is sweet in taste and helps to produce more vapor. PG is Propylene Glycol, a similar component to VG, it's used as a safe food additive and while less sweet, it makes more a more balanced taste. VG is derived by extraction from plants as raw material. PG can be derived from VG, but normally as most of the organic chemicals, it's derived initially from fossil fuel (oil/gas).

Where does the nicotine come from? What is the difference between nicotine used in LIQUA and others?

Nicotine comes as an extract from tobacco leaves. The level of purity differs, but LIQUA uses the purest available nicotine. Some competitors use a lower grade industrial use nicotine.

Is nicotine a poison? What are the risks of using nicotine, the amount of overdose and the lethal amount for an adult?

A large number of materials can be considered a poison (bring harm) to a human at a certain level of consumption over time. However, when used as directed by the safety information provided, the reasonable consumption in of Nicotine in an e-cigarette doesn't make poisoning effect. 

Most of the risks of using Nicotine associated with a temporary change of heart rate and blood pressure. For people in normal average health condition, there are no known long-term health side effects. Nicotine availability to the blood is very quick, so taking too much Nicotine by vaping is associated with visible neurological effects (fast pulse, the spinning head, weakness). Tobacco users mostly rely on increased CO2 in blood effects (not enough air feeling) to control cigarette consumption. Since e-cigarette doesn't contain CO2/CO - this trained protection doesn't work and it takes time for new vapers to use Nicotine associated mild effects to control consumption. 

Overdose is very individual for each person, but since effects are coming fast, most people can avoid overdose after mild nicotine effects. 

A lethal momentary amount is believed to be between starting from 30mg, but during vaping >90% of e-liquids exhaled and from the rest >80% is oxidized in the air before reaching the blood. Normal consumption is around 2.5ml/day. So daily consumption would be less than 1mg. Nicotine becomes 2 times less potent in the blood after 20 minutes, so at the single moment, the nicotine content will be at least hundreds of times less than minimum lethal dose.

How can we compare nicotine in cigarettes and e-cigarettes?

It's hard to compare directly the nicotine delivery from a tobacco cigarette, patch, chewing gum with the e-cigarette. But at a 2.5ml daily consumption of 1.8% nicotine e-liquid average person will get a comparable amount of nicotine as 10 lightest cigarettes (1mg). Nicotine patches and gums target around the same amount of nicotine.

What are the ingredients of LIQUA e-liquids?

Propylene Glycol(PG), Vegetable Glycerol(VG), Nicotine(Optional) and Flavoring(s)

Which flavor do you recommend starting vaping?

We recommend Traditional Tobacco or American Blend which are closest to the normal cigarette. Most smokers switching to caping typically purchase 2X Tobacco juice in 2 nicotine level + 2 X juice flavor to try what works best for them.

What nicotine level should I choose?

For cigarettes per day up to 10pcs, we recommend 6mg. For 20 pcs/day, 12mg would be a good choice. For 30 pcs/day, it will be 18mg.

How should I store LIQUA e-liquids?

Please out of direct sunlight in a dry condition at 15 to 25 ºC.

How can I check the authenticity of LIQUA?

Every bottle of LIQUA has a united QR code located on package/bottle. Scan the code with any suitable application on your smartphone and you'll automatically verify the authenticity. Also you may enter authenticity code manually 

Do you use natural extracts?

It is popular in the vaping industry to claim ‘made with natural extracts’. The fact is that many natural extracts, when inhaled, contain impurities and harmful (though naturally occurring) chemicals such as diacetyl or acetoin. These levels can be anywhere from 1000 to 10,000 times the limits we set for ourselves. For this reason, we do not specifically flavor natural extracts unless they meet our purity requirements. For us, this often requires a more complicated compounding formulation from basic components to avoid unwanted materials in the final product, but we believe this method is worth it.

Do you use water in LIQUA e-liquids?

We don’t routinely use water in our products. We discovered very early in our careers that the atomization process is much worse with high water content, so we try to keep water content to a minimum. Some flavors do contain a small amount of water when particular components require its solving property.

Do LIQUA e-liquids contain alcohol?

Some of our flavors do contain alcohol, but not enough to have any effect on the consumer. Alcohol is normally used as a solvent for some of our raw materials, so it is a necessary part of the production process. In some cases, it’s a small part of the original natural extract that doesn’t pose any risk or perceivable effect.

What is the quality of nicotine in LIQUA e-liquids?

Nicotine quality is of the utmost importance to us. People often don’t realize that bad nicotine can ruin the vaping experience. We only use nicotine with 99.9% purity, which is above USP pharmaceutical standards. Further, our nicotine has been treated to additional stages of distillation, lowering residual alkaloids and odor, resulting in the highest possible quality and best possible vape.

What are Diacetyl, Diethylene glycol (DEG), Acetoin and Acetyl Propionyl? Do you use them or other harmful ingredients in your products?

Diacetyl is a common flavor component that many brands use and which has been in the news quite a bit recently. Diacetyl is generally found in milky, vanilla-type flavors. It’s actually a natural extract that provides these distinct flavors. However, it has been found to have a negative health impact when inhaled over long periods of time. This is why we never put it in our products! 

Other flavor components with potentially adverse health effects include Acetoin and Acetyl Propionyl. These are chemicals that can give an e-liquid a pleasant buttery flavor and are common in many other brands. However, they adversely affect respiratory health (lung irritants) and we do not use them in our products. 

Diethylene glycol (DEG) can often be found in lower quality PG; It has been proven to be harmful to your health when vaped. Because we use only very high-quality raw materials, our products do not contain DEG, but we routinely test for the presence of it in every batch to ensure the highest quality. 

We pay very close attention to the latest research on e-liquid ingredients and their potential health effects. As new information comes to light, we incorporate those findings into our methodology and our recipes to ensure that vaping LIQUA is as safe as possible.

How do you prevent the presence of undesirable chemicals in LIQUA e-liquids?

Over the years, we’ve invested heavily in our R&D department. We have our own fully-equipped laboratory validated for maximum precision, an investment most other e-liquid manufacturers do not bother with. It’s an expensive endeavor, but we feel it’s worth it to get the best quality product to our customers. 

All raw materials are subjected to GC-MS & UPLC research to test for volatile organics, and ICP-MS research to test for heavy metals. Because we develop our flavors in-house, we run our tests on the pure raw materials rather than the final e-liquids, allowing us to find even the tiniest contaminations. This level of fidelity is simply impossible for most other producers. 

Many times a chemical which is perfectly safe to eat may cause adverse health effects when inhaled (such as Diacetyl). This is why we use international standards of the occupational hazard for chemicals present in the air as our ultimate guide for determining the limits of chemicals we put into our products.

How do you select reliable suppliers?

We have our own very strict standards for supplier selection and a rigorous validation process to ensure potential suppliers meet these requirements. We always check the history of our suppliers and personally visit almost all of them to verify their 9001/GMP standards. We run routine tests of all of our batches of e-liquid to ensure that the quality meets our standards. All quality control is done in our own fully-equipped laboratory.

How and in which environment do you handle with ingredients?

Our cleanroom environment is GMP food industry level and ISO Level 7. Certified to ISO9001 standards. We wash all of our bottles, nozzles, and caps in 5 stages of ultrasound cleaning and ultrapure compressed air drying. Different materials require different storage solutions. Most of them are contained in industrial refrigeration units with specific, ideal temperatures for each ingredient. 

We use a Zero Cross Contamination protocol for all materials to ensure 100% quality during the entire manufacturing process. That protocol ensures that different products never contact the same surface, tubings or tools. Dispensing is done through gravimetric measurements with 0.1% USP precision levels. Mixing results are controlled by multi-sampling from batches to ensure an even spread of material across the batch.

How does LIQUA ensure the quality of PG/VG?

We only use the USP standard, Kosher certified PG and VG in our e-liquids. These provide minimum odor, which can influence the overall taste. Most manufacturers are not concerned with the smell of these ingredients, but we think it’s very important as these odors interfere with the taste perception of the e-liquid.
