RICHMOND, Va. (AP) - Philip Morris USA has ended market tests of Marlboro cigarettes that use a high-technology filter.

A spokesman for the parent of the Richmond, Virginia-based company said today that Marlboro Ultra Smooth and Marlboro Ultra Light cigarettes were discontinued due to lower consumer acceptance.

The cigarettes use an activated carbon filter that delivers nicotine but with potentially less exposure to carcinogens.

Philip Morris stopped shipments of Marlboro Ultra Smooth to wholesalers in April. Those cigarettes were being tested in Atlanta, Tampa, Florida, and Salt Lake City for more than three years. Tests of Marlboro Ultra Lights in Phoenix and North Dakota were also discontinued.
