The intoxication caused by "kiken" drugs (law-evading drugs), such as synthetic cannabinoids, cathinones, and methoxetamine, has recently increased in Japan. We retrospectively examined the characteristics of patients poisoned with the "kiken" drugs. We included patients who presented at the emergency department at the Tokyo Metropolitan Bokutoh Hospital from January 2011 to December 2014. ⋯ Patients poisoned with the "kiken" drugs showed more severe symptoms, higher rate of habitual use, and higher average age. The annual increase in the number of the patients observed thus far is expected to decrease in the future. Maintenance of the law and expansion of medical institutions that treat patients addicted to the "kiken" drugs are warranted.

A 69-year-old man was admitted to the emergency department 3 hours after ingestion of a bleaching agent containing hypochlorous acid and sodium hydroxide in a suicide attempt. Enhanced chest computed tomography scans taken on admission indicated an edematous esophagus and air bubbles in the mediastinum. He underwent endotracheal intubation and mechanical ventilation until day 9 because of laryngeal edema. ⋯ Ingestion of any corrosive agent is known as a risk factor for esophagus cancer in the long-term. In such cases with esophageal stricture, esophagectomy is recommended for preventing esophagus cancer. Considering the age of the patient, however, he did not undergo esophagectomy.
