Understanding Nicotine Strengths: MG vs Percentage

Nicotine labeling can be confusing. Some products list nicotine in milligrams (mg) while others use percentages. Here is how to understand both.

MG Labeling

A 35mg nicotine e-liquid contains 35 milligrams of nicotine per milliliter of liquid. This is the most common labeling system in the US.

Percentage Labeling

A 3.5% nicotine product contains 3.5% nicotine by volume, which equals 35mg/ml. The percentage is simply the mg value divided by 10.

Choosing the Right Strength

Smoking Habit Recommended Strength Light (1-5 cigs/day) 3-6mg (0.3-0.6%) Moderate (5-15 cigs/day) 10-18mg (1-1.8%) Heavy (15+ cigs/day) 20-35mg (2-3.5%)
