What Nicotine Strength Should I Use? The Definitive Guide

Is there a universal answer to what nicotine strength is right? No. But there's a framework that makes the decision genuinely straightforward for most vapers — and the questions you need to answer are simpler than most people expect. Let's work through it.

The First Question: Are You Switching from Cigarettes?

If yes, your nicotine choice is determined primarily by how much you smoked. Heavy smokers (20+ cigarettes a day) need enough nicotine to effectively manage cravings — which means 20mg nic salts in most cases. This isn't optional if you want the switch to work. Going lower to "be healthier" and then finding vaping unsatisfying is one of the main reasons quit attempts fail. Get the cravings managed first. Adjust the strength later if you want to reduce.

Moderate smokers (10–20 cigarettes a day) typically do well at 10–20mg nic salt. Start at 10mg and assess after three to four days. If cravings persist, move to 20mg. Light smokers (under 10 a day) often manage on 6–10mg. Some find they can drop to 3–6mg freebase relatively quickly.

The Second Question: What Type of Device Are You Using?

Device type significantly affects appropriate nicotine strength. Pod kits and MTL devices (coils above 1 ohm) work correctly with nic salts at 10–20mg. The tight draw and controlled vapour volume mean these concentrations deliver nicotine effectively without being overwhelming.

Sub-ohm and DTL devices produce far more vapour per puff. At these higher volumes, even 6mg nicotine delivers a significant hit per puff. Experienced vapers on sub-ohm hardware typically use 0–3mg. Running 20mg through a 0.15 ohm coil at 80 watts would be extremely unpleasant.

Nic Salts or Freebase: Does This Change the Answer?

Yes, in practice. Nicotine salts are smoother at high strengths, so 20mg nic salt in a pod kit is manageable and satisfying in a way that 20mg freebase nicotine would not be. If you're using a pod kit and you want to be at 10mg or above, nic salts are the right format. If you're on sub-ohm hardware at 3mg or below, freebase nicotine in a standard e-liquid is the correct choice — at those low concentrations the smoothness advantage of nic salts isn't meaningful.

Common Signs Your Strength Is Wrong

Too low: unsatisfied cravings, returning to cigarettes, vaping far more frequently than expected without feeling satisfied. Too high: dizziness, nausea, headaches, unusual sweating after vaping. Both situations are fixable — just adjust the strength. Neither is a sign that vaping doesn't work for you.
