While the packaging claimed it had been "decocainized", no such process had actually taken place. The article stated that drinking two cups of the tea per day gave a mild stimulation , increased heart rate , and mood elevation, and the tea was essentially harmless. Despite this, the DEA seized several shipments in Hawaii , Chicago , Georgia , and several locations on the East Coast of the United States , and the product was removed from the shelves.
