How Strong Is 2mg Nicotine? Unpacking the Numbers Behind Your Vape
Jessica Tyson
17/10/2025 • 5 min readIf you’ve ever spotted “2%” or “20mg” on your vape and wondered what that actually means, you’re not alone. Whether you’re new to vaping or just exploring different nicotine strengths, understanding the amount of nicotine in your e-liquid is crucial. Let’s break it all down — no jargon, just the facts.
What Is Nicotine?
Nicotine is a substance found in tobacco products, including cigarettes and e-liquids. For those transitioning from smoking to vaping, understanding how much nicotine is in your vape is crucial. Nicotine strength in e-liquids is expressed in milligrams per milliliter (mg/ml), or as a percentage.
For example, a 20mg/ml nicotine strength is equivalent to 2%. To determine the total nicotine content, simply multiply the nicotine strength by the volume of e-liquid in your vape. This calculation helps manage your nicotine intake effectively, ensuring you get the right amount to satisfy your cravings without overdoing it. Whether you’re using a high-strength e-liquid or a bit lower, knowing the nicotine content can make a significant difference in your vaping experience.
What Does 2% Nicotine Mean?
When a vape says 2% nicotine, it simply means it contains 20 milligrams of nicotine per millilitre (mg/ml) of e-liquid. This 20mg of nicotine is the highest nicotine strength legally allowed in the UK — a cap set by the Tobacco and Related Products Regulations.
You’ll usually see this strength in nicotine salt e-liquids (also known as nic salts), which are popular because they offer a smooth experience and fast satisfaction. For anyone switching from smoking, this can feel familiar and effective — but more on that in a moment.
How Does It Compare to Cigarettes?
It’s a common question: How many puffs of a 20mg vape equal one cigarette?
On average, the nicotine yield of the average cigarette is around 1.5 mg to 12 mg, depending on the brand. So, it generally takes around 10 to 20 puffs of a 20mg vape to match the nicotine you’d get from one cigarette, although this can vary depending on your vape and how deeply you inhale.
Here’s another fun fact: Most disposable vapes in the UK come pre-filled with 2ml of e-liquid. That’s 40mg of nicotine in total, but not all of it is absorbed. Typically, a smoker absorbs around 1-2mg of nicotine per cigarette, and you’ll end up getting around 20mg delivered from a vape — roughly the same as a pack of cigarettes.
Is 2% a Lot?
In short — yes, it’s considered strong. But strength isn’t necessarily a bad thing. If you’re a heavy smoker making the switch to vaping, a 20mg vape might feel just right. It’s designed to mimic the nicotine hit you’re used to, helping with cravings and making the transition smoother. However, individual tolerance plays a significant role; what feels strong to one person might be just right for another based on their previous experience with nicotine and personal sensitivity.
However, if you’re a light smoker or more of a casual vaper, this level may feel overwhelming. Lower strengths like 3mg or 6mg might be a better starting point.
Nic Salts. vs Freebase Nicotine
Nicotine salts — which are usually what you’ll find at the 20mg strength — have a smoother throat hit and get into your bloodstream more quickly than freebase nicotine due to their higher concentration. That’s why they can feel “stronger,” even if the mg count is the same.
This makes nic salts a solid option for those looking for fast satisfaction without harshness. But again, if you’re not used to higher concentrations, start low and work your way up if needed.
E-Liquid Options
E-liquids come in a variety of nicotine strengths, ranging from 0mg to 20mg/ml, catering to different smoking habits. If you’re a light smoker, you might find lower nicotine strengths like 3mg or 5mg more suitable. On the other hand, heavy smokers transitioning to vaping may prefer higher strengths like 10mg or 12mg to manage their cravings effectively.
Nicotine salts, often available in higher strengths such as 20mg, provide a smoother throat hit and quicker nicotine absorption, making them a popular choice for those looking to quit smoking. It’s essential to choose a nicotine strength that aligns with your smoking habits and helps you manage your cravings. Always check the label for nicotine content to ensure you’re getting the right strength for your needs.
Nicotine Levels at a Glance
Nicotine Strength | Percentage | Best For |
---|---|---|
3mg/ml | 0.3% | Light or casual smokers |
6mg/ml | 0.6% | Moderate smokers |
12mg/ml | 1.2% | Regular smokers |
18mg/ml | 1.8% | Heavy smokers |
20mg/ml | 2.0% | Very heavy smokers or recent switchers |
The table above shows the range of nicotine strengths available in e-liquids. This variation allows users to select the right nicotine strength based on their personal preferences and vaping habits.
Vaping Safety and Regulations
Vaping safety and regulations are critical for ensuring a safe and enjoyable experience. In the UK, e-liquids are regulated with a maximum nicotine content of 20mg/ml, ensuring products meet safety and quality standards. Understanding nicotine content is vital for safe vaping, as nicotine overdose, though rare, can occur. Symptoms of nicotine overdose include nausea, vomiting, and dizziness. If you suspect an overdose, seek medical attention immediately.
Choosing the right nicotine strength can help prevent such risks. The UK’s Tobacco and Related Products Regulations 2016 (TRPR) ensure that e-cigarettes and e-liquids are safe for use. Vapers should be aware of these regulations and take steps to ensure their safety, such as proper storage of e-liquids and responsible disposal of devices.
Final Thoughts on Nicotine Strength
2% or 20mg nicotine isn’t for everyone — but it’s a useful tool for smokers who want an alternative that delivers comparable satisfaction. What works for one person in terms of nicotine strength may not be suitable for another, highlighting the personal nature of nicotine consumption. With UK regulations keeping things standardised and safe, it’s easier than ever to find what works for you.
