Choosing the Right Nicotine Strength for Your Vape

Technical guide · Puff Club Vape Leduc

Part of Liquids, nicotine and taste

Nicotine strength describes how much nicotine is dissolved in each millilitre of e-liquid. It is printed on the label as a number followed by "mg/mL" (milligrams per millilitre) or as a percentage. Picking the wrong level is the most common cause of an unpleasant first experience, so this guide explains how to choose and adjust it. The goal is to deliver enough nicotine to satisfy a craving without causing discomfort.

Why it happens

The confusion usually comes from three sources.

First, the unit is not obvious. A label that reads "20 mg/mL" means 20 milligrams of nicotine in every millilitre of liquid. A label that reads "2%" means the same thing, because 20 mg/mL equals 2 percent. Mixing up the two notations leads people to buy a strength far above or below what they wanted.

Second, the right strength depends on the device. A small pod system that produces a small amount of vapour per puff needs a higher concentration to deliver enough nicotine. A large tank at high power produces much more vapour per puff, so the same concentration delivers far more nicotine and becomes harsh or overwhelming.

Third, there are two kinds of nicotine. Freebase nicotine has a stronger throat sensation as the strength increases. Salt nicotine is chemically modified to produce less throat irritation at the same strength, which is why it is sold at higher concentrations for low-power devices.

Vapers also misjudge because they do not connect their cigarette history to a starting level.

Step-by-step fix

1. Read the label and convert if needed. Find the number in mg/mL. If the label shows a percentage, multiply by 10: 2% is 20 mg/mL, 1.2% is 12 mg/mL, 0.6% is 6 mg/mL.
2. Confirm the legal limit. In Canada the maximum nicotine concentration in a vaping liquid is 20 mg/mL. Any product claiming a higher number is not compliant.
3. Identify your device type. A mouth-to-lung pod or pen (tight draw, vapour held in the mouth then inhaled) works best with higher strengths, usually 12 to 20 mg/mL, often as salt nicotine. A direct-to-lung tank (loose draw, vapour inhaled straight to the lungs) at higher power works best with lower strengths, usually 3 to 6 mg/mL.
4. Match your smoking history to a starting point. This guide is for adults who already use nicotine; if you do not use nicotine, do not start. If you smoked fewer than 10 cigarettes a day, start at 3 to 6 mg/mL. If you smoked 10 to 20 a day, start at 6 to 12 mg/mL in a mouth-to-lung device or 6 mg/mL in a direct-to-lung device. If you smoked more than 20 a day, start at 12 to 20 mg/mL in a mouth-to-lung device, or 6 mg/mL in a direct-to-lung device.
5. Test with a short session. Vape as you normally would for about ten minutes, then stop and note how you feel.
6. Watch for signs of too much nicotine. Headache, nausea, dizziness, a fast heartbeat, or an upset stomach means the strength is too high. Step down one level and test again.
7. Watch for signs of too little nicotine. Strong cravings, irritability, or constant vaping with no satisfaction means the strength is too low. Step up one level and test again.
8. Change only one level at a time, and give each change a full day before adjusting further.

Prevention

Keep a note of the strength and device you settled on, so you buy the same combination again.

When you change devices, reassess the strength. A liquid that was right in a low-power pod can be far too strong in a high-power tank.

Check the label every time you buy. Manufacturers print strength in mg/mL or as a percentage, and a new bottle can look identical to your old one while containing a different level.

Purchase only from a reputable retailer in Alberta, and confirm the strength is 20 mg/mL or below before purchase.

Store liquid away from heat and direct light, and keep it in its original bottle so the strength stays visible. Nicotine degrades over time, which can reduce the effective strength and change how it feels.

If your needs change, adjust in small steps rather than jumping several levels at once.
