For how long did Tina smoke marijuana?

The correct answer indicates that Tina smoked marijuana for a duration of 5-6 years. This choice aligns with Tina's own disclosures regarding her substance use history, which is essential for understanding her overall mental and physical health context.

Understanding the length of time someone engages in substance use, such as smoking marijuana, is critical for assessing potential impacts on mental health. A duration of 5-6 years suggests a significant period where she may have experienced changes in mood, cognition, and overall functioning, especially if this use was consistent. Additionally, recognizing this timeframe can aid in evaluating her readiness for change, the potential for substance dependence, and her motivations for seeking treatment or addressing her mental health concerns.

The contextual factors behind her use, such as social, emotional, or environmental influences during those years, could also be pertinent to her current mental health state, making it important to grasp the implications of this duration adequately.
