Les cartes bancaires servent d\u2019outils de pr\u00e9cision permettant de former des lignes de poudre r\u00e9guli\u00e8res, afin de ne pas en perdre un grain. Un billet enroul\u00e9, anodin en apparence, forme un petit tube par lequel le \u00ab&nbsp;rail&nbsp;\u00bb est sniff\u00e9. De cette mani\u00e8re, des r\u00e9sidus invisibles \u00e0 l\u2019oeil nu s\u2019accumulent sur les surfaces et les objets du quotidien.<\/p>\n<h2>Billets de banque propres&nbsp;: une raret\u00e9<\/h2>\n<p>Des articles au sujet de billets de banque comportant de la coca\u00efne paraissent r\u00e9guli\u00e8rement dans les m\u00e9dias. En Allemagne, peu de temps apr\u00e8s l\u2019introduction de l\u2019euro d\u00e9but 2002, seuls quelques billets pr\u00e9sentaient des r\u00e9sidus de drogue. Mais sept mois plus tard, neuf billets sur dix \u00e9taient concern\u00e9s, la concentration sur les petites coupures \u00e9tant plus \u00e9lev\u00e9e. En Irlande, en 2007, aucun billet de banque n\u2019\u00e9tait \u00e9pargn\u00e9 par les traces de coca\u00efne.<sup>1, 2<\/sup><\/p>\n<h3>Billets de polym\u00e8re ou de papier<\/h3>\n<p>La mat\u00e9riau joue un r\u00f4le dans la propagation des r\u00e9sidus&nbsp;: les billets en polym\u00e8re dispersent les particules de coca\u00efne nettement mieux que les billets en papier. Ces derniers sont principalement compos\u00e9s de coton, ce qui les rend plus poreux, \u00e0 l\u2019instar d\u2019une \u00e9ponge. Ainsi, les r\u00e9sidus adh\u00e8rent mieux \u00e0 leur surface et compliquent leur propagation. Les billets d\u2019euro continuent d\u2019\u00eatre fabriqu\u00e9s avec du coton. Depuis quelques ann\u00e9es, certains pays comme l\u2019Australie, misent toutefois sur des billets de banque en polym\u00e8re.<sup>3,&nbsp;4<\/sup><\/p>\n<h2><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-3085 alignright\" src=\"https:\/\/www.securetec.net\/wp-content\/uploads\/2026\/03\/Wolke-aus-Kokainstaub_3x2.jpeg\" alt=\"Wolke aus wei\u00dfem Kokainpulver vor schwarzem Hintergrund\" width=\"300\" height=\"200\" \/><\/h2>\n<h2>Comparaison des traces<\/h2>\n<p>Les concentrations en coca\u00efne trouv\u00e9es sur les billets de banque varient fortement d\u2019un pays \u00e0 l\u2019autre.

En Europe, l\u2019Espagne est loin devant&nbsp;: avec 889 \u03bcg de r\u00e9sidus de coca\u00efne par billet, les coupures espagnoles pr\u00e9sentent les plus fortes concentrations. En moyenne, elles transportent pr\u00e8s de cinq fois plus de traces que les billets allemands, sans surprise, \u00e9tant donn\u00e9 la place centrale qu\u2019occupe l\u2019Espagne dans l\u2019introduction de coca\u00efne en Europe.<sup>5<\/sup><\/p>\n<h2>Des animaux drogu\u00e9s<\/h2>\n<p>En 2024, des chercheurs br\u00e9siliens ont d\u00e9couvert de la coca\u00efne et son principal m\u00e9tabolite, la benzoylecgonine, dans les tissus de rhizoprionodons, avec des concentrations plus \u00e9lev\u00e9es que chez d\u2019autres esp\u00e8ces marines.<sup>6<\/sup> L\u2019anguille europ\u00e9enne est \u00e9galement touch\u00e9e par la coca\u00efne dans les eaux fluviales.

Les mesures r\u00e9alis\u00e9es dans les grandes villes le montrent&nbsp;: dans presque toutes les villes, de la coca\u00efne et d\u2019autres substances ont \u00e9t\u00e9 d\u00e9tect\u00e9es dans l\u2019air. De plus, une \u00e9tude nationale men\u00e9e en Italie a r\u00e9v\u00e9l\u00e9 que la coca\u00efne \u00e9tait la drogue la plus r\u00e9pandue dans l\u2019air, dans les r\u00e9gions citadines tout comme les r\u00e9gions rurales, Milan arrivant en t\u00eate.
