Des recherches r\u00e9centes ont r\u00e9v\u00e9l\u00e9 que les consommateurs de marijuana pr\u00e9sentent des niveaux \u00e9lev\u00e9s de plomb et de cadmium dans leur sang et leur urine, ce qui suscite des inqui\u00e9tudes quant aux risques potentiels associ\u00e9s \u00e0 l'exposition \u00e0 ces m\u00e9taux potentiellement nocifs.<\/p>\n

La consommation exclusive de tabac signifie que quelqu'un a uniquement consomm\u00e9 du tabac et n'a fum\u00e9 rien d'autre. Pour v\u00e9rifier si quelqu'un \u00e9tait un consommateur exclusif de tabac, ils ont demand\u00e9 aux participants s'ils fumaient des cigarettes ou mesuraient une substance appel\u00e9e cotinine dans leur corps.
