Overview

Smoking is a recreational activity in which a substance, most commonly tobacco, is burnt and the smoke tasted or inhaled. This is primarily done as a form of recreational drug use, as combustion releases the active substances in drugs such as nicotine and makes them available for absorption through the lungs. It can also be done as a part of religious rituals, to induce trances and spiritual enlightenment. The most common method of smoking today is through cigarettes, either industrially manufactured or rolled with loose tobacco and a rolling paper. Other forms, though less common, are pipes, cigars, bongs, and hookahs. Smoking is one of the most common forms of recreational drug use

Historical perspective

Classification

Smoking may be classified as heavy and non-heavy, depending on the number of cigarettes consumed per day.
