MIAMI (AP) - More than 4½ tons of unwanted prescription drugs were collected in Florida by the U.S. Drug Enforcement Administration during last month's one-day pill disposal event.

The DEA said Tuesday that 121 tons of drugs were collected and destroyed nationally during the Sept. 25 "Prescription Drug Take-Back" event.

Miami DEA chief Mark R. Trouville said the goal was to ensure unwanted drugs don't end up polluting water or the environment - or end up in the hands of drug abusers.

In Florida drugs were collected at 140 sites and then incinerated. Nationally there were more than 4,000 collection sites.
