Choosing a Nicotine Strength – Refills & E-Liquids

If you are new to vaping, you may be wondering which nicotine strength you should start with.

Everyone is different and you may find you need to adjust the strength you use to begin with or over time, however please click the tabs below to find out more information about the different products and nicotine strengths available for each type of product.

Cigalike E Cig Refill Nicotine Strengths

20mg Nicotine These are usually suitable for those who smoke the stronger nicotine strength cigarettes such as Benson & Hedges Gold, Lambert & Butler Silver and Superkings.
If this strength makes you feel nauseous or lightheaded, try 18mg refills instead.

18mg Nicotine This strength is usually a good place to start. They tend suit users of cigarettes such as JPS Blue, Pall Mall Red, Superking Blue, Marlborough Red or Mayfair. If you find that this strength doesn’t satisfy your cravings, try the Extra High strength.
If 18mg makes you feel nauseous or lightheaded, move down to 12mg.

OK NicSalt E Liquid Nicotine Strengths

Our NicSalt e liquid range is the perfect middle ground when it comes to vaping. This range has a balanced 50/50 PG/VG ratio which makes them suitable for use with both standard vape kits and lower powered sub ohm kits. Nicotine salt vape juices are a great choice for beginners as they allow you to vape with higher nicotine strengths but don’t give the harsh throat hit you often get with PG based e-liquids at higher nicotine strengths. With this in mind, our NicSalt flavours all contain 18mg of nicotine.

Another benefit to nicotine salt e liquids is that they tend to provide a faster nicotine hit, helping to stave off those cravings. Read our guide to nicotine salts if you’d like to find out more.

18mg Nicotine New vapers using classic kits such as the OK Ego Vape Pen or Aspire K2 Kit. NicSalt liquids may also work well with lower powered sub ohm kits such as the Aspire PockeX or Innokin EZ Watt (with 0.8 ohm coil).

NicSalts should work well with any vape tank with an above-ohm coil or sub-ohm tanks using a mod at lower power settings.

3mg Nicotine Our full sub ohm range is available in 3mg nicotine as this is the most popular strength with sub ohm tanks. The reason for the low nicotine content being that sub ohm produces larger clouds of vapour which provides more nicotine delivery in one go than less powerful kits. Cherry Sherbet
