Vapers Q & A
We decided to create a separate page for some easily accessible, basic e-cigarette answers. We’ll try to keep the questions and answers brief and to the point. For more detailed explanations you can visit our other FAQ pages, broken down by category (ie. mods, tanks, e-juice, etc.).
Q. What’s a vape?
A. Vape or vapes are a shortened term for vaporizers. Vaporizers heat a material to either release the essential components from plant material in the form of vapor (method used in heat not burn technology) or to vaporize a specially prepared mixture of flavor and liquid with or without nicotine, referred to as e-liquid or e-juice.
Q. Is vaping safe?
A. There have been no long term studies done because the vape industry is only about ten years old, but the Royal College of Physicians in England have publicly announced that their belief is that vaping is about 95% less detrimental to health than vaping.
Q. Is vaping legal?
A. In Canada and the USA governments have been busy creating guidelines and laws to protect consumers. Most vaping equipment is legal and e-liquids with nicotine are legally sold in the US and Canada. There are currently laws restricting the importation of nicotine into Canada.
Q. Will governments ban e-cigarettes?
A. All indications point to increased oversight in the manufacture and delivery of e-juice, possible taxation and possibly a ban on flavors or marketing that would appeal to people under the legal age. In Canada, Bill S-5 is currently in third reading.
Q. Is there a risk to “side-stream vapor”?
A. Currently most laws affecting smokers apply to vaping as well. No conclusive evidence of passive vaping risks have been determined. It’s best to follow the same rules you would with smoking until more science has been done.
Q. Is vaping expensive?
A. On average a vaper spends about a sixth as much as he would on smoking.
Q. What’s in e-juice?
Q. Does e-juice cause popcorn lung?
A. No, at least there’s never been an documented instance that we know of. There was a concern in the past that certain sweeteners may cause a reaction in the lungs but these ingredients have been phased out by e-juice manufacturers.
Q. How long does a 30ml bottle of e-liquid last?
A. It really depends on the type of vaping equiment, how often you vape and the blend of components (VG/PG ratio) but you can easily get a month from a 30ml bottle.
Q. What do the PG/VG numbers mean on e-juice?
A. About 90% of the ingredients in e-juice is PG and VG, with the remaining 10% flavoring and nicotine. PG (Propylene Glycol – a man made glycerin) and VG (Vegetable Glycerin – a naturally occurring glycerin) have different properties. PG is thinner (more runny), vaporizes at lower temperatures and has a drier throat hit than VG. For lower wattage use, PG dominant will vaporize more easily. For higher wattage devices (sub-ohm) a higher viscosity VG vaporizes slower and provides a cloudier vapor than a high PG. Typical for a 1.8 ohm vape would be 70/30 PG to VG, for a 0.4 ohm vape, the reverse, an 80/20 VG to PG would be preferable.
Q. Do vapes explode in your face or pocket?
A. These incidents usually occur with what are called unregulated mods, where the battery is hooked directly to the atomizer with no integrated circuit to monitor and regulate the vape. Most vapers prefer a much easier regulated setup that doesn’t require building coils or working out resistance.
Q. I want to quit smoking. What strength nicotine e-juice should I start with?
A. Nicotine strength is sold in a usual range of between 3mg. to a high of 24mg. 24mg is really very strong and could be compared to an unfiltered, full flavor cigarette. For typical beginner use start within the range of 8mg to 18mg. If you avoided “Light” cigarettes use a higher nicotine, if you preferred Light cigarettes start at 8mg.
Q. I’ve heard that sub-ohm vaping kits require less nicotine, is that right?
A. Yes. If you’re switching from an Atlantis or Kanger 1.8 ohm coil to a tank running at 30W or more, cut the nicotine amount you usually vape in half, to start.
Q. What’s the deal with MTL and DTL?
A. Smokers are used to taking a puff into there mouth and then inhaling, vapers call this mouth to lung. Most beginner kits cater to the MTL style because it’s familiar. If you decide to advance to a high wattage multi-coil system you will find that a Direct to Lung inhale with a wider open airway on the tank is preferable.
Q. Is there a lot of maintenance required for e-cigarettes?
A. No, not really. You have to 1) add e-liquid as your tank empties, probably 2 or 3 times a day. 2) You have to keep your battery charged and/or keep a spare. And 3) every few weeks you need to change the coil.
Q. Why do I need to change the coil on my vape?
A. The coil consists of cotton to absorb the juice and metal coils to heat it.The cotton will become clogged and less absorbent over time and the wire will gain resistance, resulting in less flavor and vapor.
Q. How long will a coil last.
A. Typical coils last 3 to 6 weeks. Vaper’s who “chain vape” or prefer certain flavors like cream or vanilla may experience a shorter life from the coil.
Q. What about the new “heat not burn” e-cigs?
A. Time will tell how well they’re received. In a HNB, real tobacco is heated to a temperature suitable to release the nicotine and flavor, but apparently none of the other compounds in tobacco.
Q. What do they mean about a closed or open system for vaping?
A. Disposable e-cigarettes don’t have replaceable parts so you throw them away when you’re done. There are no user changeable components and as such it is a Closed System. With the existing vape marketplace, you can buy the tank from one vendor, a coil from another and the battery mod from a third competing manufacturer. All pieces are interchangeable (except some but not all coils) between most systems, hence Open System.
