A lot of people bought something called cannabis from stores in a place called Michigan last year. They spent more money than before, which made the people who sell it and the government very happy. Cannabis is a plant that some adults use to feel relaxed or have fun. The stores that sold it had many other stores selling the same thing nearby, so they tried to make their prices lower to get more customers. But even with low prices, more people kept buying cannabis from them. Read from source...

1. Introduction: The introduction should provide a clear and concise overview of the topic, without using vague terms like "unprecedented surge" or "staggering". A more accurate way to describe the growth in cannabis sales is by providing specific numbers and percentages, such as "a 25% increase from the previous year".
2. Tax Revenue: The article should mention that most of the tax revenue generated by cannabis sales goes to the state, not local governments. This is important for readers to understand the allocation of funds and how they are used. Additionally, the article should provide a breakdown of the different types of taxes collected (e.g., sales tax, excise tax, etc.) and their respective rates.
3. Consumer Spending and Penetration: The article could have provided more details on how consumer spending is calculated and what factors influence it. For example, does it include only cannabis products or also accessories and services? How are the penetration rates determined and compared to other states or markets?
4. Competition and Price Dynamics: The article should acknowledge that price dynamics are influenced by various factors, such as supply chain issues, regulations, quality standards, etc. It could have explored how these factors affect the cannabis market in Michigan and whether they differ from other states or markets.
5. Retail Availability: The article does not explain why retail availability is important for consumer spending and what role it plays in the market. It should provide examples of how limited retail options impact sales growth, such as long wait times, product shortages, etc. It could have also compared the number of licensed dispensaries in Michigan to other states or markets and their average transaction values.
6. Cross-Border Trading: The article does not adequately address the issue of cross-border trading and its impact on Michigan's cannabis market. It should explain how this phenomenon occurs, what are the main drivers behind it (e.g., price differences, availability, quality, etc.), and how it affects both consumers and businesses in Michigan. Additionally, it could have provided some estimates or statistics on the magnitude of cross-border trading and its potential implications for the future of the market.
