Amphetamine lacing of an Internet-marketed neutraceutical.

A 25-year-old woman presented with abdominal pain after taking an imported herbal weight-loss product. A urinary toxicology screen was positive for amphetamine, which the patient denied taking. On further investigation, the neutraceutical was found to contain an amphetamine derivative banned by the US Food and Drug Administration (FDA). Although the patient had discontinued use of the supplement before hospitalization and her symptoms steadily improved with appropriate treatment, a report was made to the FDA. Similar reports from cities across the United States prompted the FDA to confiscate shipments of the product before it could be distributed further nationally while they investigate claims against the product.
