Smoking was the act of igniting a substance in order to taste or inhale the byproducts of the thermal and chemical reaction to fire released in smoke. Some narcotic chemicals and medicines could be inhaled in this manner. On Earth, it was the traditional way of consuming tobacco, a practice that can be traced back to the peace pipe rituals of some Native American groups.

Background information Edit
During the making of Star Trek: The Original Series, Gene Roddenberry and others associated with the production fought NBC and Desilu so that cigarettes were omitted from the series. "Even with the heaviest smokers, including myself, I fought for it," Roddenberry recalled. "In the end, it paid off for everyone; I think everyone now agrees that the original episodes would not be rerunning so successful if we had yielded to advertising pressure and put a 'twenty-third century cigarette' into the mouth of Kirk and others." (The Making of Star Trek: The Motion Picture, p. 43)
While having a bit of leftover time, John Teska created a shot of a member of Species 8472 sitting in a hallway relaxing with a cigarette and a couple of bottles by his side, much the way actors do in their off time. The shot was included in the VOY Season 4 DVD special feature "The Birth of Species 8472 ".
In the "Outtakes" section of ENT Season 1 DVD, a scene appears in which Scott Bakula should have entered the set for T'Pol's quarters but unlike in the episode, he waited behind the door to the set with two drinks and was smoking a cigarette, causing T'Pol actress Jolene Blalock to laugh.
