The evolving high: new designer drugs of abuse.

Over the past decade, emerging drugs of abuse and synthetic derivatives of more traditional agents have flooded the market. While Europe was the first to experience a surge in the use of drugs such as synthetic cathinones and cannabinoids, poison centers throughout the United States have seen a dramatic rise in calls related to these new designer drugs of abuse. In the majority of cases, care is largely supportive but significant medical and traumatic complications may occur. Providers must be aware of the ever-changing trends in abuse, so that they may optimally care for poisoned patients.
