Ketamine analogues are emerging dissociative substances structurally related to ketamine and increasingly detected on drug markets worldwide. This study aimed to characterize patterns of use, user profiles, and associated health outcomes in France. We conducted a retrospective analysis of cases involving ketamine analogues reported to the French Addictovigilance Network up to 31 December 2024....
Abstract Introduction: Misuse of inhaled nitrous oxide is a growing concern in France. It is known to alter concentrations of vitamin B12, which is required as a cofactor for methionine synthase and methylmalonyl-CoA mutase activity. Hence, measurement of the concentrations of cobalamin metabolism biomarkers, including vitamin B12, homocysteine, and methylmalonic acid, could assist in the...
Ephenidine, diphenidine, and methoxphenidine belong to the family of diarylethylamines that are psychoactive substances derived from lefetamine (N, N-di-methyl-1,2-diphenylethylamine, also called L-SPA). These dissociative anesthetic compounds act as potent and selective N-methyl-d-aspartate receptor antagonists and were recently classified as narcotic drugs in France. The available data...
