Guide to Vaping – Everything You Need to Know Before You Start

Vaping has quickly become one of the most popular alternatives to smoking. Whether you're trying to quit cigarettes, cut back on tobacco, or just looking for a less harmful option, vaping offers a wide range of choices. But with so many devices, liquids, and terms out there, getting started can feel confusing.

This guide is here to clear things up. We’ll walk you through everything you need to know, from how vaping works and what types of devices are available, to nicotine strengths, safety tips, and what to expect as a beginner.

What Is Vaping?

Vaping is the act of inhaling vapor produced by a device that heats a liquid known as e-liquid or vape juice. Unlike traditional cigarettes, which burn tobacco, vapes use heat to create vapor. This process is cleaner, produces no ash or tar, and usually smells better than smoke.

Most e-liquids contain four main ingredients: propylene glycol (PG), vegetable glycerin (VG), flavouring, and nicotine (optional). The liquid is stored in a tank or pod, which connects to a coil that heats the liquid and turns it into vapour when you inhale.

Types of Vapes

Not all vapes are the same. There are several types of devices, each suited to different needs and experience levels.

Disposable Vapes

These are small, ready-to-use devices that come pre-filled with e-liquid. You simply open the pack and start vaping. Once it runs out, you throw it away. Disposables are ideal for beginners, people on nights out, or those who don’t want to deal with charging or refilling.

Pros:

• Easy to use

• No maintenance

• Compact and lightweight

Cons:

• Not environmentally friendly

• Limited flavour and strength options

• More expensive over time

Pod Systems

Pod systems are small rechargeable devices that use pods instead of tanks. The pods may be pre-filled or refillable. These devices are a popular choice for ex-smokers and anyone who wants a compact vape with good performance.

Pros:

• Easy to carry

• Suitable for nicotine salts

• Quick to charge

• Good for beginners and regular users

Cons:

• Some use proprietary pods which cost more

• Smaller battery than larger devices

Vape Pens

These are slim tube-style devices that usually come with a small tank and replaceable coils. Vape pens are slightly more powerful than pods and often used with regular freebase nicotine liquids.

Pros:

• More vapour than pods

• Affordable and easy to find

• Beginner-friendly

Cons:

• Coils need to be changed

• Not as compact as pods

Box Mods

Box mods are larger, more powerful devices used by experienced vapers. They have more customisation features like adjustable wattage, temperature control, and larger tanks.

Pros:

• Big clouds and strong flavour

• Long battery life

• Custom settings

Cons:

• Bulkier design

• Steeper learning curve

• More expensive upfront

E-Liquid Basics

The liquid used in your vape is just as important as the device. E-liquids come in many flavours, nicotine strengths, and PG/VG ratios.

Nicotine Strengths

If you're quitting smoking, choosing the right nicotine strength is key. Too strong, and you might feel dizzy. Too weak, and it may not satisfy cravings.

• 20mg – Suitable for heavy smokers

• 10mg – Medium strength, good for light to moderate smokers

• 5mg – Low strength, best for casual use or those cutting back

• 0mg – No nicotine at all

Salt Nicotine vs Freebase Nicotine

• Salt Nicotine: Smooth on the throat and absorbs faster. Best used in pods and low-power devices.

• Freebase Nicotine: Stronger throat hit, used in standard liquids and vape pens or box mods.

PG/VG Ratios

• Higher PG (e.g. 70/30): Stronger throat hit, better for flavour and smaller clouds.

• Higher VG (e.g. 70/30 VG/PG): Smoother hit with bigger clouds, more suited to powerful devices.

How to Use a Vape Device

Most vapes follow the same basic setup, though each type may vary slightly.

1. Charge your device fully before using it for the first time.

2. Fill your tank or pod with your chosen e-liquid if it’s not pre-filled.

3. Let it sit for a few minutes (called priming the coil) to avoid burning it out.

4. Turn on the device with the fire button or draw-activation.

5. Inhale slowly and steadily, holding the vapour briefly before exhaling.

Take short breaks between puffs if you’re new to vaping. Too much too quickly can cause light-headedness.

Common Vaping Mistakes to Avoid

Like anything new, beginners often run into small issues. Here are a few common ones and how to avoid them.

• Vaping too fast: Chain-vaping can overheat your coil and burn the liquid.

• Using the wrong strength: Start with a medium level and adjust as needed.

• Not priming the coil: Always give your coil a few minutes to soak before the first puff.

• Mixing flavours too often: Flavour ghosting happens when you switch e-liquids without changing coils or cleaning the pod.

• Overcharging your device: This can damage the battery over time.

Is Vaping Safer Than Smoking?

Current evidence suggests that vaping is significantly safer than smoking traditional cigarettes. While not entirely risk-free, vaping eliminates many of the harmful chemicals found in tobacco smoke such as tar and carbon monoxide.

Public health bodies in the UK and Ireland have recognised vaping as a useful harm-reduction tool for adult smokers. That said, vaping is not recommended for non-smokers or young people.

Can Vaping Help You Quit Smoking?

For many people, vaping has played a big role in finally quitting cigarettes. One of the biggest advantages is that it gives smokers nicotine without the tar, smoke, and thousands of harmful chemicals found in tobacco. You still get the familiar hand-to-mouth action and a satisfying hit, which helps ease the transition.

In fact, studies have shown that vaping can be more effective than nicotine patches or gum for some smokers trying to quit. The key is choosing the right setup and using it consistently. You can start with a nicotine strength that matches your smoking habit and then gradually reduce over time if that’s your goal.

Some people stop using nicotine altogether but continue vaping with 0mg liquids. Others move away from vaping completely once they no longer feel cravings. There’s no one-size-fits-all, but vaping gives you more control over the process.

Vaping Flavours – What to Expect

One of the biggest things that sets vaping apart from smoking is the variety of flavours. You’re not limited to just tobacco. Whether you like fruity, minty, creamy, or even drink-inspired tastes, there’s something for every palate.

Popular flavour categories include:

• Fruity: Mango, strawberry, blueberry, watermelon

• Menthol or Mint: Ice mint, spearmint, menthol blast

• Dessert: Vanilla custard, donut, cheesecake

• Tobacco: Rich tobacco, smooth blend, caramel tobacco

• Drinks: Cola, energy drink, lemonade, coffee

Some vapers like to stick to one favourite. Others rotate between a few different ones depending on their mood. Flavour is also a big part of why vaping can help you quit smoking, it gives a much more pleasant experience.

Is Vaping Legal in Ireland?

Yes, vaping is legal in Ireland, but it is regulated. All e-liquids and vape devices must follow EU rules under the Tobacco Products Directive (TPD). That means maximum nicotine strength is capped at 20mg, bottle sizes are limited to 10ml for nicotine-containing liquids, and all products must be properly tested and labelled.

You must be at least 18 years old to buy vape products in Ireland. Most reputable shops and websites carry out age checks to ensure compliance.

Ireland does not currently tax e-liquids, but this could change in the future as vaping becomes more widespread. For now, prices remain lower than in countries where heavy vape taxes exist.

Looking After Your Vape – Simple Maintenance Tips

Vape devices don’t need a lot of maintenance, but a little care goes a long way. Keeping your device in good shape means better performance and a longer lifespan.

Basic maintenance checklist:

• Keep it clean: Wipe down the outside and mouthpiece regularly

• Replace coils when needed: If you taste burning or the flavour drops, it’s time for a new coil

• Store upright: This prevents leaks and keeps liquid flowing properly

• Avoid overcharging: Unplug when fully charged to protect battery health

• Use the right liquid: High VG liquids can clog small pod systems

If you look after your kit, it will last longer, perform better, and save you money on replacements. Pod systems usually need new pods every few days or weekly, depending on use. Vape pens and mods just need coil changes when the flavour drops or the liquid starts tasting burnt.

Side Effects and Safety

Vaping is considered safer than smoking, but like anything involving nicotine, there are still side effects to watch out for.

Common short-term effects:

• Dry mouth

• Throat irritation

• Coughing (especially when starting)

• Mild dizziness if nicotine is too strong

These effects usually settle after a few days as your body adjusts. If the symptoms continue, try a different nicotine strength or liquid blend. Some people are sensitive to high PG or strong flavours, so switching to a smoother option can help.

Long-term safety

No one can say for certain what the effects of vaping will be over decades. However, compared to smoking, the risk appears to be much lower. Public Health England reported that vaping is likely 95 percent less harmful than smoking. That number may change over time, but the current science is clear, vaping is a far better option than cigarettes.

Vaping and Travel

You can bring your vape with you while travelling, but there are rules you need to know.

Airport tips:

• Always pack your vape device in carry-on, not checked baggage

• Liquids must follow the 100ml rule and be placed in a clear plastic bag

• Turn your device off during flights

• Never vape on the plane (it’s illegal on all airlines)

Vape laws also vary by country. Some places like Thailand, Singapore, and India have banned vaping completely. Always check local regulations before flying abroad with vape products.
