6-MN: a nicotine-like chemical appearing in some products

Why we’re flagging this: A nicotine-like chemical called 6-methyl nicotine, or 6-MN, has appeared in some vape and oral products outside Wales.

Last checked: 30 September 2026

What is 6-MN?

6-MN is chemically similar to nicotine, but it is not the same substance. Chemicals like this are sometimes called nicotine analogues — in plain English, chemicals made to act in a nicotine-like way.

What does the research say?

A 2026 laboratory study compared nicotine and 6-MN in e-cigarette aerosol. It found important differences between them and concluded that 6-MN should not be treated as a safer nicotine alternative.

What don’t we know?

The research is still developing. We do not have good evidence that 6-MN use is common among young people in Wales.

Seeing products internationally does not mean they are widely used here.
