Nicotine strength is not a score. The right choice is the lowest strength that comfortably suits an adult’s established use without causing cravings or unpleasant effects. Anybody who does not already use nicotine should not start.
Read the unit: E-liquid is usually labelled in mg/ml. Pouches may show mg per pouch, mg/g or both. Those numbers cannot be compared as though they mean the same thing.
E-Liquid Strength
Irish nicotine e-liquid is capped at 20mg/ml. A person’s previous smoking pattern, device power and style of inhaling can all affect how a given strength feels. Higher-power devices generally use lower-strength liquid; compact mouth-to-lung pod kits are commonly paired with 50/50 e-liquid or nicotine salts.
Nicotine-Pouch Strength
Check the amount per pouch. Extra-strong products are not suitable starting points and can cause nausea, dizziness, hiccups, irritation or a racing heartbeat. Remove the pouch if you feel unwell.
Signs the Strength May Be Too High
- Nausea or dizziness
- Headache, shakiness or a racing heartbeat
- Unpleasant throat hit or mouth irritation
- Feeling unwell shortly after use
Signs You Need Proper Quitting Support
If cravings, withdrawal or dependence are difficult to manage, speak with an HSE stop-smoking adviser, GP or pharmacist. Do not keep increasing strength and hope the label eventually develops clinical qualifications.

Responsible-use note: Vaping and nicotine products are for adults aged 18 and over. Nicotine is addictive. Vaping is not harm-free, and people who do not smoke or use nicotine should not start.
For quitting support, the HSE recommends speaking with a stop-smoking adviser, GP or pharmacist and using licensed stop-smoking medicines. Read the HSE guidance on vaping and nicotine.
The Bottom Line
Start conservatively, compare the correct unit and pay attention to how you feel. If you need help reducing or stopping nicotine, use qualified support rather than a stronger product.
