So when you're answering a case question you want to create a structure which is specific to the question. Your structure of micro / macro is very generic and doesn't answer the question specifically.
For example, you want to consider more broadly the:
1. Economic effects
- Consider what new businesses could be started
- Evaluate the impact on tax revenue, job creation, and other economic indicators
- Consider the potential for an increase in tourism related to cannabis consumption
2. Public health effects
- Consider the potential impact on mental health, substance abuse, and overall well-being
- Discuss any measures that could be put in place to mitigate negative health effects
- Note that this may offset the economic benefits if people drop out of the workforce due to ill-health
3. Criminal justice effects
- Understand the potential change in arrest rates, conviction rates, and incarceration rates related to cannabis offenses
- Discuss any unintended consequences, such as an increase / decrease in drug-related crimes
4. Social effects
- Consider the impact on social norms, attitudes towards drug use, and the stigma associated with cannabis consumption
- Discuss any potential benefits or drawbacks for marginalized communities
As a rule of thumb, if your structure could be applied to a peanut butter factory it's too generic - micro / macro could be applied to a peanut butter factory, so you need to get a few levels deeper.
Good luck in your prep!
