Methamphetamine and MDMA: 'Safe' drugs of abuse

Methamphetamine and MDMA have been called safe drugs of abuse. Worldwide there is an increased consumption of these drugs, which has become a focus of research in South Africa. As the number of methamphetamine users has increased in many African countries, it is essential that emergency care practitioners are able to diagnose and manage intoxication with methamphetamine, MDMA, and other derivatives. The most common presentations include restlessness, agitation, hypertension, tachycardia, and headache while hyperthermia, hyponatraemia, and rhabdomyolysis are among the most common serious complications. Most deaths are secondary to hyperthermia complicated by multiple organ failure. A number of laboratory analyses should be obtained if locally available. We provide a review of the current recommended general and specific management approaches. Benzodiazepines are the first line therapy for hyperthermia, agitation, critical hypertension, and seizures. Patients with serious complications are best managed in an intensive care unit if available. Emergency centres should create protocols and/or further train staff in the recognition and management of intoxication with these 'not so safe' drugs.
