One of the central themes of the story is the way in which smoking can serve as a form of self-medication. For Jim, smoking is a way to cope with the stresses and anxieties of everyday life. He describes smoking as a way to "slow things down" and to "keep the world at bay." This idea is reinforced by the fact that Jim's smoking habit is triggered by specific events, such as a stressful job interview or a difficult conversation with his girlfriend.
However, the story also suggests that smoking can have negative consequences for identity and self-perception. Jim is aware that his smoking habit is unhealthy and that it is a source of anxiety for his girlfriend. He also feels a sense of shame and guilt about his smoking, and he is constantly trying to hide it from others. This suggests that smoking can be a source of conflict and internal struggle, as it can both provide comfort and cause distress.
The story also explores the social aspects of smoking. Jim describes the camaraderie and sense of community that he feels among other smokers. He finds comfort in the fact that there are others who share his habit and who understand the struggles and pleasures of smoking. However, the story also suggests that this sense of community can be isolating, as it can create a barrier between smokers and non-smokers.
Ultimately, "Smokers" is a complex and nuanced exploration of the role of smoking in identity and self-perception. The story does not offer any easy answers, but it does provide a thought-provoking look at the ways in which smoking can both positively and negatively impact our lives.
