Knowing the daily purchase limits for marijuana in Michigan is crucial for both residents and visitors. According to Michigan law, an adult aged 21 or older can legally purchase and possess up to 2.5 ounces of marijuana in a single day from licensed dispensaries within the state. However, it’s essential to understand that different rules may apply when traveling across city or county lines. For the latest updates on Michigan’s cannabis laws and regulations, always consult trusted sources such as your local law enforcement agency or the Michigan Department of Licensing and Regulatory Affairs (LARA).
