What is being seen?
Nicotine-like chemicals including 6-methyl nicotine (6-MN) have appeared in international e-cigarette and oral nicotine-style products. These compounds are chemically related to nicotine but should not be assumed to have the same evidence base or risk profile.
What the research says
A 2026 peer-reviewed toxicology study comparing nicotine and 6-MN aerosols in a laboratory airway model found different toxicological and chemical profiles and concluded that 6-MN should not be treated as a safer nicotine alternative.
What we do not know
This is an emerging research signal, not a Wales prevalence estimate. We do not have good evidence that 6-MN use is common among young people in Wales, and international product availability should not be used to imply local uptake.
