Choosing the right nicotine strength — 3mg, 6mg, 12mg, 20mg, 35mg or 50mg — for your vape in South Africa. A no-nonsense guide from The Vape Shop.
Why nicotine strength matters
The nicotine level in your e-liquid — measured in milligrams per millilitre (mg/mL) — decides how satisfied you feel after a vape, how harsh the throat hit is, and how quickly you get through a bottle. Too low and you'll chain-vape and still feel unsatisfied; too high and you'll cough, feel light-headed, or write off vaping entirely. Most people who fail to switch from cigarettes to vaping do so because they started at the wrong strength.
The two nicotine types: freebase vs salt
Freebase nicotine is the traditional form, used in sub-ohm tanks and larger devices. It hits harder in the throat as the mg goes up, which is why freebase is usually 3mg or 6mg. Nicotine salts (nic salts) are smoother — they use benzoic acid to lower the pH, so 20mg salt feels similar to 6mg freebase in throat hit but delivers nicotine to the bloodstream much faster, closer to a cigarette. Nic salts are what almost every disposable vape and pod device uses.
Freebase strengths: 0mg, 3mg, 6mg, 12mg
0mg is for cloud chasers and flavour-only vapers. 3mg is the most common freebase strength for people using bigger sub-ohm setups — enough to satisfy without harshness. 6mg suits heavy freebase users. 12mg is rare in modern vaping and generally too harsh for sub-ohm tanks.
Salt strengths: 20mg, 35mg, 50mg
20mg (2%) is the sweet spot for most South African vapers using a pod device — satisfying without being overwhelming. 35mg suits heavier ex-smokers (pack a day or more). 50mg is the ceiling and only appropriate for people using low-power pod devices; anything more powerful will make 50mg unbearable.
How to pick based on your smoking history
A quick guide: light smoker (under 10 a day) or occasional social smoker — start at 20mg salt in a pod device or 3mg freebase in a bigger tank. Moderate smoker (10–20 a day) — 20mg or 35mg salt in a pod, or 6mg freebase in a sub-ohm. Heavy smoker (20+ a day) — 35mg or 50mg salt in a compact pod. Never-smoker — do not start vaping.
Signs you picked the wrong strength
Too high: coughing, throat burn, dizziness, headache, nausea. Fix: drop to the next strength down. Too low: chain-vaping, cravings after 15 minutes, going back to cigarettes. Fix: step up one level or switch from freebase to salts.
South African context
South Africa's forthcoming excise duty on nicotine (currently R2.90/mL plus a set rand per device) makes higher-strength salts marginally more cost-effective per satisfying puff than low-strength freebase, since you use less liquid to feel satisfied. This is one reason 20mg and 50mg salts dominate the SA market.
FAQ
Can I mix nic salts and freebase?
Not in the same bottle. Use each in the device it's made for — salts in pods, freebase in sub-ohm tanks.
Is 50mg salt safe?
It is legal and widely sold. Nicotine is addictive and 50mg delivers a lot of it fast, so it is only appropriate for heavy ex-smokers using a low-power pod device.
Will lower nicotine help me quit?
Stepping down over time is a common approach, but it requires being satisfied at each rung — jump down too fast and you will relapse.
