20mg is the strongest nic salt e-liquid legally available in the UK. But strong does not mean uncomfortable. This guide explains exactly what 20mg feels like, who it is right for and whether you should be starting on it.
Quick Answer: 20mg nic salt is strong in terms of nicotine concentration but smooth in terms of feel. The benzoic acid formulation removes the harshness that makes 20mg freebase unpleasant, so 20mg nic salt is comfortable to inhale. It is the right starting strength for heavy smokers (15 or more cigarettes a day) and anyone switching directly from disposable vapes, which almost all used 20mg. It is a lot of nicotine if you chain-vape. Used in normal sessions it is designed exactly for this use case.
20mg/ml means there are 20 milligrams of nicotine in every millilitre of e-liquid. A full 10ml bottle of 20mg nic salt contains 200mg of total nicotine. A standard 2ml refillable pod filled with 20mg nic salt holds 40mg of total nicotine across the whole pod.
20mg is the legal maximum permitted under the UK's Tobacco and Related Products Regulations 2016 (TRPR). You cannot legally buy a higher-strength nic salt e-liquid in the UK. Any product sold above this concentration has not met TRPR requirements and should be avoided.
Despite being the maximum available, 20mg nic salt was the standard strength in virtually every disposable vape sold in the UK before the June 2025 ban. It was also the strength used in the vast majority of prefilled pod systems. Millions of UK vapers use 20mg nic salt daily without issue because the benzoic acid formulation makes the strength comfortable at levels that would be unvapeable in freebase form.
Whether 20mg feels strong depends heavily on your background and how you vape. For a heavy smoker switching on day one, 20mg in a pod kit may feel about right: satisfying, fast-acting and smooth. For a light smoker or someone who has never smoked, it could feel overwhelming within a few puffs.
The key distinction is between the nicotine concentration and the experience. 20mg freebase would be almost unvapeable for most people because the high pH creates intense throat irritation at that concentration. 20mg nic salt uses the salt formulation to lower the pH, which removes that harshness entirely. Many vapers describe 20mg nic salt as feeling no rougher than 6mg freebase on the throat, despite delivering more than three times as much nicotine per ml.
| Product | Nicotine per ml | Throat Hit | Who It Suits |
|---|---|---|---|
| 20mg nic salt | 20mg | Smooth (salt formula) | Heavy smokers, ex-disposable users, new switchers |
| 10mg nic salt | 10mg | Very smooth | Moderate smokers, long-term vapers, step-down |
| 18mg freebase | 18mg | Harsh for many vapers | Experienced vapers who prefer throat hit |
| 20mg freebase | 20mg | Very harsh | Rarely used; few vapers tolerate this comfortably |
| 6mg freebase | 6mg | Mild, manageable | Light vapers, sub-ohm users, long-term low-strength |
20mg is the correct starting strength for a specific and very common group of vapers. If you fall into any of the categories below, 20mg is likely the right choice for you.
Your body is accustomed to a significant daily nicotine intake. Starting below 20mg means your cravings will not be adequately managed, which is the primary reason new vapers return to cigarettes in the first week. 20mg provides the fast, satisfying nicotine delivery your body expects. You can step down to 10mg once you have been comfortably off cigarettes for four to eight weeks.
Virtually every disposable vape sold in the UK used 20mg nic salt. If you are moving from a disposable to a refillable pod kit, matching the strength you were already using gives the most seamless experience. Starting lower than your disposable is likely to feel underwhelming and may prompt you to vape more than necessary to compensate.
If you are uncertain whether 10mg or 20mg is right for you, starting at 20mg is the safer choice. It is easier to step down from 20mg to 10mg if you find 20mg more than you need than it is to manage persistent cravings on 10mg and risk returning to smoking. Most brands stock both strengths in the same flavours, so adjusting is simple.
While 20mg is suitable for most people switching from cigarettes, it is too high for some vapers, particularly light smokers or those with lower nicotine dependency. If you experience any of the following within the first day or two of vaping 20mg, drop to 10mg.
Dizziness or lightheadedness after a few puffs. Headache during or after vaping. Nausea or an unsettled stomach. A noticeably rapid heartbeat. Shaky hands or feeling unusually anxious. If any of these appear, stop vaping immediately, drink water and step down to 10mg. These are your body's signals that the nicotine concentration exceeds what you need.
Feeling jittery or unable to concentrate after a session. Finding that you feel worse after vaping than before. Noticing that you only need a couple of puffs to feel satisfied but keep reaching for the device out of habit. These suggest your body is getting more nicotine than it needs and 10mg would serve you better for daily use.

For adult smokers switching from cigarettes, yes. 20mg nic salt in a pod kit replicates the nicotine delivery of cigarettes in a format that is regulated under TRPR 2016 and substantially less harmful than smoking. All products stocked at Vapers Pantry are MHRA-notified and fully compliant. Vaping at any nicotine strength is intended for adult smokers or current vapers only and should not be used by non-smokers.
Yes. 20mg/ml is equivalent to 2% nicotine concentration. Some brands, particularly those with roots in the US market, use percentage labelling instead of mg. You may see both on packaging from different manufacturers. In the UK, TRPR requires mg/ml labelling as standard on products sold here.
No. 20mg nic salt must only be used in low-wattage pod kits and MTL devices operating below 18W with coils above 0.6ohm. Using 20mg nic salt in a sub-ohm tank or high-power mod delivers a dangerously large amount of nicotine very quickly, causing dizziness, nausea and a rapid heartbeat. Match the strength to the device: 20mg in a pod kit, 3mg to 6mg freebase in sub-ohm setups.
For a typical vaper using a pod kit, a 10ml bottle at 20mg usually lasts two to four days. Because 20mg satisfies cravings quickly, most vapers take fewer puffs per session than they would on a lower strength. Heavy vapers or those who chain-vape may go through a bottle in one to two days. Most people find 20mg is more economical per session than lower strengths because fewer puffs are needed each time.
