How We Calculate This
Our calculator uses a research-backed formula to estimate your ideal nicotine strength:
The Formula (Simplified)
- • Pod systems: 60% efficiency
- • MTL tanks: 70% efficiency
- • Sub-ohm: 85% efficiency (higher due to lung absorption)
- • Nicotine salt: 1.25× (absorbs 20-40% faster)
- • Freebase: 1.0× (baseline)
- • Mouth-to-lung (MTL): 1.0× (baseline)
- • Direct-to-lung (DTL): 1.4× (delivers ~40% more per puff)
Scientific Sources
Our methodology is based on peer-reviewed research:
- Nicotine absorption from electronic cigarettes (Addiction Biology, 2021) - Device type significantly affects nicotine absorption rate
- Comparison of Nicotine Plasma Levels (JAMA Network Open, 2020) - Salt nicotine shows 20-40% faster absorption than freebase
- Nicotine yields from cigarettes (Regulatory Toxicology and Pharmacology, 2019) - Average nicotine absorbed per cigarette: 1.0-1.5mg

Understanding Nicotine Strengths in Vaping
When you switch from cigarettes to vaping, choosing the right nicotine strength is crucial for a successful transition. Too low and you'll crave cigarettes; too high and you'll feel sick. Our calculator above gives you a personalized starting point, but understanding how nicotine works in vaping helps you fine-tune your experience.
How Nicotine Delivery Differs from Cigarettes
Cigarettes deliver nicotine extremely efficiently through combustion. The smoke carries nicotine directly to your lungs where it absorbs almost instantly into your bloodstream. You feel the effect within seconds.
Vaping delivers nicotine more slowly. The aerosol particles are larger than smoke particles, and nicotine absorption happens partly in your mouth and throat before reaching your lungs. This means you might need to vape for 5-10 minutes to get the same nicotine satisfaction as a 5-minute cigarette.
This difference is why many new vapers mistakenly think vaping doesn't work for them. They expect the instant hit of a cigarette and give up too soon. Give yourself 2-3 weeks to adjust to the different delivery pattern.
Nicotine Salt vs Freebase: Which Should You Choose?
The two main types of nicotine in e-liquid behave very differently.
Freebase Nicotine
Freebase is the original form of nicotine used in e-liquids. It's the same nicotine found in cigarettes and nicotine patches. Key characteristics:
- Stronger throat hit - Creates a noticeable sensation in your throat, similar to cigarettes
- Slower absorption - Takes slightly longer to feel effects
- Harsh at high strengths - Most people find anything above 18mg uncomfortable
- Best for: MTL tanks and anyone who wants a cigarette-like throat sensation
Nicotine Salt
Nicotine salts use a modified form of nicotine that's smoother to inhale. They were developed specifically for high-nicotine pod systems. Key characteristics:
- Smoother experience - Comfortable even at 50mg
- Faster absorption - Closer to cigarettes in satisfaction speed
- Higher strengths available - Commonly 20-50mg
- Best for: Pod systems, heavy smokers, and anyone finding freebase too harsh
Our recommendation for smokers switching to vaping: Start with nicotine salts in a pod system. The fast absorption and high nicotine strengths make the transition easier. You can always switch to freebase later if you prefer the throat hit.
Choosing by Device Type
Your device dramatically affects how much nicotine you should use.
Pod Systems (20-50mg Salt)
Pod systems like JUUL, Vuse, and refillable pods are designed for high-nicotine use. They produce small amounts of vapor and are meant to be puffed frequently throughout the day. The low vapor output compensates for the high nicotine concentration.
Heavy smokers (20+ cigarettes/day) should start at 50mg. Moderate smokers (10-20/day) work well with 35mg. Light smokers can start at 20-25mg.
MTL Tanks (12-25mg Salt or 6-18mg Freebase)
Mouth-to-lung tanks produce more vapor than pods but still use a restricted, cigarette-like inhale. They're a middle ground between pods and sub-ohm devices.
With nicotine salts, stay at 25mg or below to avoid overdoing it. With freebase, 12-18mg works well for most ex-smokers.
Sub-Ohm Devices (3-6mg Freebase)
Sub-ohm tanks and mods produce large clouds of vapor. Because you're inhaling so much vapor, you need much lower nicotine. Using high-strength nicotine in a sub-ohm device can cause nicotine poisoning.
Most sub-ohm users vape at 3mg or 6mg freebase. Some use up to 12mg, but this is uncommon. Never use nicotine salts above 20mg in a sub-ohm device.
Signs You're Using the Wrong Strength
Too Low (Need Higher)
- Still craving cigarettes after vaping
- Chain vaping constantly without satisfaction
- Feeling irritable or having withdrawal symptoms
- Going through e-liquid extremely fast
Too High (Need Lower)
- Nausea or stomach discomfort
- Dizziness or lightheadedness
- Headaches, especially after vaping
- Racing heart or anxiety
- Only needing 2-3 puffs to feel satisfied
Tips for a Successful Transition
- Don't start too low - It's better to start slightly too high and reduce than to start too low and give up
- Give it time - The different delivery pattern takes 2-3 weeks to feel normal
- Vape on cravings - Use your vape whenever you'd normally smoke
- Stay hydrated - Vaping can cause dry mouth; drink plenty of water
- Buy backups - Don't run out of e-liquid or coils
- Reduce gradually - If you want to lower nicotine, step down slowly over weeks or months
Safety Considerations
While vaping is widely considered less harmful than smoking, nicotine itself carries risks:
- Nicotine is addictive and raises blood pressure
- Pregnant women should avoid nicotine products
- Keep e-liquids away from children and pets - nicotine is toxic if swallowed
- If you experience severe symptoms, stop vaping and seek medical attention
This calculator provides general guidance based on typical use patterns. Individual responses to nicotine vary. Listen to your body and adjust accordingly.
Frequently Asked Questions
What nicotine strength should I start with as a beginner?
If you smoke less than 10 cigarettes per day, start with 20-25mg nicotine salt in a pod system, or 6-12mg freebase in an MTL tank. Heavier smokers (20+ cigarettes) typically need 35-50mg salt or 18mg freebase to satisfy cravings.
What's the difference between nicotine salt and freebase?
Nicotine salt is chemically modified to be smoother at high strengths, allowing for 20-50mg concentrations without harsh throat hit. Freebase is traditional e-liquid that provides a stronger throat sensation but becomes uncomfortably harsh above 18mg.
Is 50mg nicotine a lot?
50mg is the highest common concentration, designed for heavy smokers using low-vapor pod devices. The small vapor output means you absorb less nicotine per puff. In a sub-ohm device, 50mg would be far too much - those users typically use 3-6mg.
How do I convert nicotine percentage to mg/mL?
Multiply the percentage by 10. For example, 5% nicotine equals 50mg/mL, 2.5% equals 25mg/mL, and 0.6% equals 6mg/mL. This is a simple 1:10 ratio.
Can I use nicotine salt in any device?
Nicotine salts work best in low-power pod systems and MTL tanks. Using high-strength salts (35mg+) in a sub-ohm device can cause nicotine overdose symptoms like nausea and dizziness. Stick to 20-25mg max for MTL tanks and 3-6mg for sub-ohm.
Why do I still crave cigarettes after vaping?
You may need a higher nicotine strength, or your device may not be delivering nicotine efficiently. Try increasing your strength by one level, or switch to a pod system which delivers nicotine faster. Some cravings are also habitual rather than nicotine-related.
How long does it take to adjust to vaping from smoking?
Most smokers fully adjust within 2-4 weeks. The first few days are hardest as you adapt to a different throat sensation and nicotine delivery pattern. Be patient and don't reduce nicotine too quickly.
Should I gradually reduce my nicotine strength?
Only if you want to. Many vapers happily stay at the same strength for years. If you want to reduce dependence, step down gradually (e.g., 50mg to 35mg to 25mg) over several weeks. Never rush - failed reduction often leads back to cigarettes.
What happens if I use too high a nicotine strength?
You may experience dizziness, nausea, headache, or a racing heart. These symptoms are temporary and mean you should use a lower strength. If symptoms are severe, stop vaping and drink water. The effects typically pass within 15-30 minutes.
Why does sub-ohm vaping use lower nicotine?
Sub-ohm devices produce much more vapor per puff, so you absorb more nicotine even at lower concentrations. Using 50mg in a sub-ohm device would be equivalent to chain-smoking cigarettes and cause immediate nicotine overdose symptoms.
