Key takeaways
- Start with your device, not the juice. Your kit decides most of it — a small pod wants high-strength nic salt at 50/50; a sub-ohm tank wants low-strength, high-VG freebase.
- Nicotine strength: match how much you smoked. Heavier smokers start higher (or on salts); light or social smokers start low; 0mg if you don’t want any.
- Freebase or salts? Salts for small pods and a strong, smooth hit; freebase for bigger devices and low strengths.
- PG/VG ratio follows the device too: 50/50 for pods, 70/30 or higher-VG for clouds.
- Flavor is the only free choice — pick what you enjoy; it’s what keeps you off cigarettes.
Choosing vape juice looks harder than it is, because a wall of bottles hides a simple truth: your device makes most of the decision for you. Get the four things below right, in order, and the juice will work in your kit and satisfy you. Only the last one, flavor, is genuinely up to taste. Here’s the decision, step by step.
Start here: what device do you have?
This is the step most guides bury, and it’s the one that matters most: your device sorts you into one of two lanes, and each wants a different kind of juice:
- Small MTL pod or pod-pen (the pocket-sized kit most ex-smokers use) → wants higher-strength nicotine, usually nic salts, in a 50/50 ratio. Thin liquid, strong hit, small clouds.
- Sub-ohm tank or bigger mod (the cloud-making kit) → wants low-strength, high-VG freebase juice. Thick liquid, gentle hit, big clouds.
Put the wrong juice in and it shows fast: high-VG juice starves a small pod coil (dry, burnt hits), and a high-strength salt in a sub-ohm cloud machine delivers a punishing dose of nicotine. So before anything else, know which lane you’re in. Not sure what to buy yet? Our best pod vapes and best e-liquid vape pens guides are the place to start.
Step 1: Pick your nicotine strength
Match it to how much you smoked, then adjust. Too high and you’ll feel queasy; too low and you’ll chain-vape.
| You were… | Rough starting strength |
|---|---|
| A heavy smoker (a pack+ a day) | 20mg salt in the UK/EU (the legal cap); in the US, salts go higher — around 25–50mg. Or high-strength freebase in a bigger kit |
| A moderate smoker (½–1 pack) | 10–20mg salt, or 6–12mg freebase |
| A light / social smoker | 3–6mg, or a low-strength salt |
| Not a smoker / want none | 0mg |
This is a starting point, not a rule; it’s easy to move up a step if a strength isn’t holding your cravings. Our guide to nicotine strengths and percentages goes deeper on dialing it in, and if you’d rather skip nicotine entirely, nicotine-free (0mg) vaping is a full option. If you don’t already smoke or vape, there’s no reason to start at any strength.
Step 2: Freebase or nicotine salts?
These are the two forms nicotine comes in, and your device (plus how strong you want the hit) decides it:
- Choose nic salts if you’re on a small pod and want a strong, smooth, fast hit — the ex-smoker’s default. Salts stay smooth even at 20mg+, which freebase can’t.
- Choose freebase if you’re on a bigger, lower-strength setup, or you like a sharper throat hit at 3–6mg.
The full breakdown of why they feel different is in nicotine salts explained.
Step 3: Match the PG/VG ratio to your kit
The ratio on the bottle (50/50, 70/30, max VG) is really a device-fit decision:
- 50/50 — thin enough to wick in small pods and MTL coils. The default for pod kits.
- 70/30 or higher VG — thick, cloudy, smooth; built for sub-ohm tanks. Too thick for a small pod (it’ll dry-hit).
Get this wrong and juice either leaks (too thin for the tank) or burns (too thick for the coil). Full detail in PG vs VG explained.
Step 4: Choose your flavor (the fun part)
This is the only step with no wrong answer: it’s taste, and it’s the thing that actually keeps people off cigarettes. The broad families:
- Fruit: the most popular; bright, easy all-day vapes.
- Dessert / creamy: richer (custard, cake, tobacco-vanilla); great in the evening.
- Menthol / ice: cool and sharp; often blended into fruits.
- Tobacco: for a familiar, cigarette-like profile, especially early in a switch.
- Drinks / candy: everything from cola to sherbet.

The 30-second cheat sheet
| If you have… | Get juice that’s… |
|---|---|
| A small MTL pod (Caliburn, XLIM, etc.) | Nic salt, 10–20mg, 50/50 |
| A pod-pen / beginner AIO | Salt or freebase, 10–20mg, 50/50 |
| A sub-ohm tank / cloud mod (coils under ~1.0Ω) | Freebase, 3–6mg, 70/30 or higher VG |
| Any device, no nicotine wanted | 0mg, ratio to match the device |
Common mistakes to avoid
- High-VG juice in a small pod. It’s too thick to wick — you’ll get dry, burnt hits. Use 50/50.
- Too-high nicotine. Overshoot and you’ll feel sick (nausea, dizziness, racing heart). Start lower and work up.
- Too-low nicotine. If it isn’t satisfying you, you’ll just vape constantly. Step up a strength instead.
- Buying a big bottle of an untried flavor. Sample small first; flavor is personal.
- Ignoring cost. Refilling from a bottle is far cheaper than pre-filled pods — see how much vapes cost.
Get the device-fit right (strength, form, ratio) and the juice will work; get the flavor right and you’ll actually enjoy it. For the bigger picture on what’s in the bottle, start with what vape juice is.
FAQ
How do I know what vape juice to buy?
Start with your device. A small pod wants high-strength nic salt in a 50/50 ratio; a sub-ohm tank wants low-strength, high-VG freebase. Then pick a nicotine strength to match how much you smoked, and a flavor you like.
What nicotine strength should a beginner get?
Match your smoking: a pack-a-day smoker often starts on salts in a pod — around 20mg in the UK/EU (the legal cap), or 25–50mg in the US; a light smoker 3–6mg; if you don’t want nicotine, 0mg. It’s easy to move up if a strength isn’t satisfying you.
Should I use freebase or nic salts?
Nic salts for a small pod and a strong, smooth hit (the ex-smoker’s default). Freebase for a bigger, low-strength setup or if you like a sharper throat hit.
What PG/VG ratio is best for my device?
50/50 for small pods and MTL kits; 70/30 or higher-VG for sub-ohm tanks built for clouds. The wrong ratio can leak or dry-hit.
Does the flavor affect how the juice performs?
Not the device-fit — strength, form and ratio do that. Flavor is purely taste. Sweet, dark or creamy flavors can gunk a coil a little faster, but that’s minor.
