What was the reason Tina gave for stopping marijuana use?

Tina's reason for stopping marijuana use highlights significant personal and health-related reflections. She indicated that it "wasn't fun anymore," which points to a shift in her perception of the substance's effects on her life. This suggests that the initial recreational benefits she may have experienced diminished over time. Additionally, the concern about it being "bad for her asthma" illustrates a clear awareness of the impact of marijuana on her physical health. This combination of losing enjoyment and recognizing health risks is a strong motivator for her to discontinue use, as it reflects both a change in her lifestyle perspective and a proactive approach to her well-being.

In contrast, while other options address important factors like social relationships, financial constraints, and family influence, they do not encapsulate the dual personal enjoyment and health considerations that Tina identified for her decision.
