E-liquid FAQ

E-liquid (e-juice) is about basic chemistry and, of course, what really feels and tastes good. Browse the FAQs here to get a better grasp of what goes into e-liquid and how to find what's just right for you.

What is e-liquid? 

E-liquid is a solution of propylene glycol (PG) and/or vegetable glycerin (VG), optional nicotine amounts, and food-grade flavorings. The solution vaporizes when heated and translates flavor and throat hit when inhaled. 

What's the difference between nicotine & tobacco? 

Although the FDA classifies electronic cigarettes and vapor products as tobacco products, nicotine and tobacco are not just synonyms for one thing. The two are factually and scientifically separate. Tobacco in traditional cigarettes is the dried leaves of a tobacco plant that contain nicotine naturally. Nicotine as a liquid may be extracted from many different natural sources and then added into a PG/VG base along with flavorings. Even tomatoes contain small amounts of nicotine! 

What if I get e-liquid on my hands/clothes? 

Our e-liquid is water soluble and easily washes off your hands and clothes. If you rub your eye after handling e-liquid, flush it thoroughly with cool water. Be sure to keep e-liquid away from children and pets.  

How is nicotine measured in e-liquid?  

Nicotine is measured in milligrams (mg) per milliliter (mL). 

How much nicotine do I want? 

Choose a strength based on comfort in your throat ("throat hit") when inhaling. If you're vaping too high, your throat will be irritated or you will cough. If you're directly inhaling, even zero mg will make you cough. That's why is best to try the different nicotine levels before buying e-liquids. 

What is propylene glycol (PG)? What does vegetable glycerin (VG) do? 

Wikipedia or other reference sties can give you the full lowdown on PG. You will find it in many foods, medicines, and toiletries, so you are already consuming it on a daily basis. "Smoke" at concerts and such is created by vaporizing PG. It is "generally recognized as safe" to inhale by the FDA. However, a small portion of the population is allergic to PG. 

You may be puzzled that PG is also anti-freeze. Most anti-freeze products were made of ethylene glycol many years ago. PG is now favored because it is dra-matically less toxic than EG. However, if you're still opposed to  anti-freeze in general, then by that same logic you shouldn't ingest salt either. 

PG is responsible for transporting the flavoring mainly but also contributes to throat hit. VG produces more visible vapor than PG but mutes flavor and throat hit. PG is thinner than VG; the ratio of PG and VG will affect the wicking properties of your e-liquid: too much wicking and you may get "burnt hits" more frequently; too little wicking and you will experience flooding. 

Generally, standard pre-manufactured atomizers work well with 80/20 and 50/50 PG/VG. Vapers who use more advanced gear such as RBAs and RDAs for building their own atomizers often prefer higher amounts of VG. 

What if I'm allergic to propylene glycol? 

A small portion of the population is allergic to PG. The symptoms are usually extreme throat irritation and/or ulcers in the mouth. Most people who have this allergy are already aware due to PG's prevalence in everyday foods and toiletries. However, a person can develop an allergy to something at any time in life. 

Vegetable glycerin (VG) only liquids are available, but we do not offer them at SmokeScreen. A VG base reduces throat hit and does not translate flavor as well as a PG/VG mix. It also makes e-liquid thick causing it to wick (therefore, vape) less efficiently. Keep in mind if you opt for a VG-only liquid, most flavorings are are already based in PG. Research plenty before choosing a VG e-liquid vendor. 

Am I vaping too much? 

You can still get that yucky nic stomach ache or headache by the end of the day if you puff a lot. Consider lowering your nic strength or vaping less. 

What's up with flavors? 

Nothing can exactly duplicate the taste of burning tobacco and paper. Just find a flavor you like a lot. 

Do you have marijuana flavor? 

No. E-cigs already get enough sideways glances because much ignorance about them still exists among the general public. Since marijuana is still an illegal substance in Mississippi we have no intention of associating it with e-cigs. 

What's up with cinnamon "eating" tanks?? 

Natural cinnamon, black licorice, some banana flavors, and citrus e-liquids have been known to break down plastics. Any flavorings made with essential oils may do this. Once that happens, the common chemicals used in making plastics will begin leaching into your e-liquid itself. If you intend to vape cinnamon or other "corrosive"  flavors, we recommend using metal cartomizers or a good quality glass tank such as from Aspire

If you use cinnamon in a plastic tank and notice a cloudiness/scratchiness or discoloration of the tank, replace that tank immediately. Even if you use a glass tank, check the o-rings and seals periodically as these flavors may break down those materials as well. These types of e-liquids should be stored in glass containers. If you notice a change in a plastic bottle, do not use that e-liquid any more. 

Should I use tobacco flavor? 

Each new vaper has his/her own preferences. Most settle on 2-3 favorites as you may stop tasting a flavor if you use it continuously for days or weeks.
