Smoking is the process of flavoring, cooking, or preserving food by exposing it to the smoke from burning or smoldering plant materials, most often wood. Meats and fish are the most common smoked foods, though cheeses, vegetables, and ingredients used to make beverages such as whisky,smoked beer, and lapsang souchong tea are also smoked.

In Europe, alder is the traditional smoking wood, but oak is more often used now, and beech to a lesser extent. In North America, hickory, mesquite, oak, pecan, alder, maple, and fruit-tree woods, such as apple, cherry, and plum, are commonly used for smoking. Other fuels besides wood can also be employed, sometimes with the addition of flavoring ingredients. Chinese tea-smoking uses a mixture of uncooked rice, sugar, and tea, heated at the base of a wok. Some North American ham and bacon makers smoke their products over burning corncobs. Peat is burned to dry and smoke the barley malt used to make whisky and some beers. In New Zealand, sawdust from the native manuka (tea tree) is commonly used for hot smoking fish. In Iceland, dried sheep dung is used to cold-smoke fish, lamb, mutton, and whale.

Smoking is a practice in which a substance, most commonly tobacco or cannabis, is burned and the smoke is tasted or inhaled. This is primarily practised as a route of administration for 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 rituals, to induce trances and spiritual enlightenment^{[citation needed]}.

The most common method of smoking today is through cigarettes, primarily industrially manufactured but also hand-rolled from loose tobacco and rolling paper. Other smoking implements include pipes, cigars, bidis, hookahs, vaporizers and bongs. It has been suggested that smoking-related disease kills one half of all long term smokers but these diseases may also be contracted by non-smokers. A 2007 report states that about 4.9 million people worldwide each year die as a result of smoking.

Smoking is one of the most common forms of recreational drug use. Tobacco smoking is today by far the most popular form of smoking and is practiced by over one billion people in the majority of all human societies. Less common drugs for smoking include cannabis and opium. Some of the substances are classified as hard narcotics, like heroin, but the use of these is very limited as they are often not commercially available.

Michael Voltaggio (born September 29, 1978) is an American chef residing in Pasadena, California. Voltaggio is the winner of the sixth season of Top Chef, Bravo's cooking competition reality show, where he competed with his brother, Bryan Voltaggio. The two ended in the finale, alongside Kevin Gillespie, with Michael winning the contest. Top Chef Head Judge Tom Colicchio said of Voltaggio, “Out of all the cooks that have come through the show, Michael is the most talented—both from a sensibility and technical standpoint. He has the chops to pull off what he’s trying to do.”

Voltaggio did not have the money to attend culinary school, so he did a long apprenticeship at The Greenbrier resort in West Virginia under master chef Peter Timmins. He later held jobs at the Ritz Carlton in Naples, Florida under chef Arnaud Berthelier and Charlie Palmer's Dry Creek Kitchen in Healdsburg. During his tenure as Chef de Cuisine at The Bazaar by Jose Andres, the restaurant was nominated for the James Beard Foundation Award for Best New Restaurant in 2008.
