QIs vaping bad for your health?

A recent study at the University of St. Andrews in Scotland found that the cancer danger of vaping is almost as low as for nicotine replacement therapies like patches and gum — less than one percent. “This study should put to rest any doubt within the tobacco control movement about whether vaping greatly reduces health risk compared to smoking,” wrote Boston University’s Dr. Michael Siegel.

QWhat strength nicotine do I need
AYou should choose your nicotine strength based on the “throat hit” it gives you. Our recommendation is for ultra light smokers, try 6mg. For heavy smokers, 18mg is usually the sweet spot. This varies with each person, but these are general guidelines to help get you in the right direction.
QHow is nicotine measured

Nicotine in e-liquid is measured in milligrams (mg) per milliliter (mL). Compared to cigarettes, you will take in much less nicotine, but still feel satisfied.

QWhat is Sub-Ohm
ASub-Ohm is what people refer to when your resistance is below 1.0ohm. Sub-Ohm has become very popular with vapers looking for the biggest clouds of vapor. It usually requires a Max-VG liquid with very low nicotine (0mg-6mg) concentration. Sub-Ohm is a good idea for vapors looking to customize their own personal device and get very large vapor clouds. Please make sure you have an understanding Ohms Law and follow all recommended battery safety practies before deciding to take the leap into the Sub-Ohming circle.  
QWhat is resistance
AThe resistance of a replacement heads is broken down in “ohm”. The lower your ohm, the faster the liquid will heat up. So a 1.8ohm will heat up faster than a 2.1ohm coil. Most people prefer the 1.8ohm coils because it is just warm enough without burning out the coil too fast.
QWhat is 510 Threading
AThis is the threading that is used on the inside of your battery. It is referred to most often with mechanical mods.
QWhat does MAH mean?
AThis means milliampere hour. In simple terms, the bigger the number, the longer your battery will last. So a 1,000mah battery lasts longer than a 500mah battery.
QWhat should I look for when buying a device
AThere are hundreds of vaping devices in all shapes and sizes available today. When deciding on your first vaping device purchase, you will most likely be making your decision based on the design, price, and performance. It’s difficult to give generic advice on this due to these reasons.

However, please keep this in mind: You will always need a device charged up and available. For example, if you decide to buy a second-generation device (e.g. an Ego) you will probably want to consider having a few extra batteries you can keep charged up and on hand.

Secondly, you will always want to make sure you have e-liquid in your inventory. You don’t want to run out when you want to vape the most! Many vapors keep a small bag with all their accessories inside.
QCan you save money vaping?
AYes, you can! But how much you will save will depend on several factors: How much you were smoking. How much cigarettes cost where you are living. The amount you spend on devices. For some vapers, this becomes quite an interesting hobby! With that being said, with a good setup you can save a considerable amount of money versus traditional cigarettes.
QWhat strength juice should I buy?
AThe general rule on this is that the heavier the smoker you are, the stronger the e-liquid you should purchase. It is important to note though that depending on how much you vape, you may want to consider a lighter e-liquid if you are vaping a lot to help reduce the chance of throat irritation.
QWhat is PG & VG Liquids
APG (propylene glycol) and VG (vegetable glyerine, or glycerol) are flavor carriers in your e-liquid that create the vapor. Both PG and VG are very popular in products of all kinds fit for human consumption. PG is know for having a stronger “throat hit” but produces less of a vapor cloud. VG has a slightly sweet flavor and produces a very noticeable cloud of vapor. Many e-liquids contain a combination of both ingredients to help even out the cons of each.
QHow does vaping work
ANearly every vaping device functions with the same basic features. A battery charges a coil which in turn heats up a e-liquid to a temperature where it becomes vapor. This vapor is them inhaled.
QWhat is vaping
AVaping is a short form on referring to the use of a device such as an e-cigarette, personal vaporizer, mod, or APV. Any device used to produce a vapor for consumption. There are hundreds, if not thousands of vaping devices on the market today.
QWhat does PG & VG do to my lungs?

Vegetable Glycerin (VG) is a thick, sweet liquid, extracted from plants, and is primarily responsible for the vapor produced. It is traditionally employed in the following industries: Food, Pharma, Botanical, and personal care products. Propylene Glycol (PG) is a colorless, non-toxic, odorless liquid, that is responsible for assisting in the delivery of the active ingredient(s), in our case this would be nicotine. The US FDA approves both compounds as GRAS (Generally Recognized As Safe).

QMy vape tastes burnt
AIt sounds like you might be in need of a replacement coil head. Normally your replacement head will last roughly 2 weeks, but it is possible they can burn out much more quickly. When installing the new replacement head, be sure to allow the device 5-10 minutes before use. This gives the new coil head time to soak up the liquid, preventing a burnt taste and ensuring your new coil head does not burn out as quickly.
