Because most cigar and pipe smokers do not ______, as a group they have a lower risk of cancer than cigarette smokers.
Artyom0805 [142]

Because most cigar and pipe smokers do not<u> </u><u>inhale the smoke</u> , as a group they have a lower risk of cancer than cigarette smokers.

The cigarettes, cigars, and pipe tobacco are made out of dried tobacco leaves. The other substances are usually added for flavor and to make smoking more gratifying. The smoke from these products is a complex mixture of chemicals produced by flaring tobacco and its additives.

There are at least 70 known chemicals to cause cancer. These cancer-causing chemicals are referred to as carcinogens.

It is so because cigars and pipes are usually believed to be less harmful way than to smoke tobacco. It was once a trend to use cigars in the 1990s, luring/dragging the young and the old.

Most of the people think cigars are less harmful to their health, but they actually pose the same risk for oral cancer as cigarettes do. Many cigar smokers don't inhale the smoke, but still the risk for oral, throat, and esophageal cancer is alike as for cigarette smokers.

Ivan

The correct option is this: MARIA'S WATER USE IS CONSUMPTIVE.

Water use can be consumptive or non consumptive. Consumptive water use refers to the process of using water in such a way that the water used can not be returned to the water resources system.

The water that Maria used to shower, the one she drank and the one she used to wash her laundry are waste water, which are not returned to the central water resources system, thus, Maria's water use is consumptive.
