While the past 40 years have seen significant declines in adult smoking, this is not the case among young adults, who have the highest prevalence of smoking of all other age groups. At a time when just about everyone knows that smoking is bad for you, why do so many college students smoke? Is it a short lived phase or do they continue throughout the college years? And what happens after college, when they enter the “real world”? Drawing on interviews and focus groups with hundreds of young adults, Lighting Up takes the reader into their everyday lives to explore social smoking. Mimi Nichter argues that we must understand more about the meaning of social and low level smoking to youth, the social contexts that cause them to take up (or not take up) the habit, and the way that smoking plays a large role in students’ social lives.
