NICOTINE STRENGTH

Nicotine strength in eliquid is measured in milligrams of nicotine per milliliter (mg/ml). The /ml is often left out on labels. If a label says 18mg, it means the concentration is 18mg/ml.

Most products first seen in Canada had nicotine levels no higher than 18 mg/ml. When big brands got involved they offered products with nicotine levels of as much as 59 mg/ml.

Health Canada set the maximum level at 65 mg/ ml while a European Union (EU) directive doesn’t allow levels above 20 mg/ml.
