Vaping is the process of inhaling vapour from an electronic cigarette or vape device. The vapour is created by heating an e-liquid, which usually contains nicotine, flavourings, and a mix of propylene glycol (PG) and vegetable glycerine (VG).

Vaping gives a similar sensation to smoking but without burning tobacco, making it a popular alternative for smokers in the UK.

According to Public Health England, vaping is estimated to be around 95% less harmful than smoking.

Unlike cigarettes, vapes don’t produce tar or carbon monoxide – the two most dangerous chemicals in tobacco smoke. While not risk-free, vaping is considered a significantly safer option for adult smokers looking to quit.

Most e-liquids contain four main ingredients:

1. Propylene Glycol (PG) – carries flavour and gives a throat hit.
   
2. Vegetable Glycerine (VG) – creates thicker vapour clouds.
   
3. Flavourings – food-grade flavour concentrates.
   
4. Nicotine – optional and available in various strengths.

Choosing the right PG/VG ratio affects how smooth or strong the vapour feels.

If you’re switching from smoking, choose a nicotine level based on your cigarette use:

• Light smoker (under 10 a day): 3–6mg
  
• Moderate smoker (10–20 a day): 6–12mg
  
• Heavy smoker (20+ a day): 12–20mg
  

You can always lower the strength gradually to reduce your nicotine intake over time.

Yes, nicotine-free e-liquids are available and widely used. Many people vape without nicotine purely for the flavour or to satisfy the hand-to-mouth habit. These e-liquids are ideal for those who have already quit nicotine but still enjoy vaping.

On average, a vape coil lasts 1–2 weeks depending on how often you use your device and the type of e-liquid.

You’ll know it’s time to change the coil if you notice:

• A burnt or unpleasant taste
  
• Less vapour production
  
• Gurgling or leaking

Sweet or dark e-liquids can shorten coil lifespan, so regular maintenance helps.

Disposable vapes are pre-filled, pre-charged, and designed for single use. They’re perfect for beginners or short-term use.

Refillable vape kits allow you to add your own e-liquid, replace coils, and recharge the device — making them more eco-friendly and cost-effective long term.

Disposable vapes were banned in the UK from June 1, 2025.

The ban prohibits the sale and supply of single-use vapes in shops and online to reduce environmental damage and youth vaping.

Many former smokers use vaping to quit smoking successfully.

Vaping delivers nicotine without burning tobacco, helping to manage cravings while reducing exposure to harmful chemicals. Over time, you can gradually lower your nicotine strength until you no longer need it.

There are two main vaping styles:

• MTL (Mouth to Lung) – similar to smoking a cigarette. You draw vapour into your mouth first, then inhale.
  
• DTL (Direct to Lung) – you inhale straight into your lungs, producing more vapour and stronger flavour.

Your choice depends on your preferred sensation and device type.

Yes, but there are some rules:

• Keep your vape kit and batteries in your hand luggage.
  
• Store e-liquids in bottles under 100ml.
  
• Do not vape on planes or in airport terminals.

Always check your airline’s vaping policy before you travel.

Common causes of vape leaks include:

• Overfilling the tank
  
• Damaged seals or worn O-rings
  
• Leaving the device on its side
  
• Thin e-liquid in a high-powered device

Check your coil and seals regularly, and avoid overfilling to prevent leaks.

To clean your vape:

1. Disassemble the tank and remove the coil.
   
2. Rinse all non-electrical parts in warm water.
   
3. Let them dry completely before reassembling.

Regular cleaning helps maintain flavour quality and coil life.

A shortfill is a larger bottle of nicotine-free e-liquid, usually 50ml or 100ml, that leaves space for a nicotine shot.

Simply add a nic shot, shake well, and enjoy your preferred strength. This setup is popular in the UK for cost savings and flexibility.

Yes. Just Vapes and Juices stocks a wide range of nicotine shots and nicotine salts to help you customise your e-liquids.

Nicotine salts offer a smoother hit and faster nicotine absorption — ideal for ex-smokers who want a quick craving fix.
