Both 5 check here and six are thought to be further more metabolised by conjugation towards the glucuronide and sulfate derivatives. Expertise in the key routes of metabolism should enable the intake of mephedrone being confirmed by drug exams, and far more precise perseverance of your will cause of Uncomfortable side effects and likely for toxicity.[forty eight]
