Aim: Poppers have become legal in France since June 2013. Is their liberalisation associated with an increase of severe side effects observed?
Methods: To identify elevated methaemoglobinaemia related to poppers abuse, we reviewed all methaemoglobin concentrations measured in Nantes university hospital, during 12 months.
Results: Methaemoglobin concentrations were superior to 25% in three cases of poppers consumption that occurred after the legalisation.
Conclusion: Evaluating the prevalence of elevated methaemoglobinaemia could help to monitor severe complications of poppers use in France.
