Ann Arbor Cannabis—Know Before You Go 

Recreational Marijuana in Michigan  

Adult-use cannabis and possession by people 21 and older was legalized in the state of Michigan in 2018. Washtenaw County is home to over 20 medical and adult-use (recreational) cannabis dispensaries. You’ll cannabis provisioning centers located throughout the Ann Arbor area.  

In addition, both Ann Arbor and Ypsilanti have “microbusinesses” that grow, process, and sell cannabis in the same location. These small businesses are new in Michigan and growing in popularity. 

Consuming in Ann Arbor and Michigan—Laws to Follow 

Adults 21 years and older may buy up to 2.5 ounces of cannabis products per day, and that’s the maximum you’re allowed to have on your person unless you are storing it in a Michigan residence (then you can have up to 10 ounces, but it needs to be secured). Concentrates are weighed in grams, and by law, you can have up to 15 grams of concentrates on your person. 

Before You Leave the Store with Your Goods Know the Rules 

What you CANNOT do: 

• Cannot smoke or otherwise consume in a car or on any Michigan road. This goes for both drivers AND passengers. 
• Cannot drive under the influence of cannabis. 
• Cannot smoke in public places. You can smoke on private property, but not where the public can see you—think back yard vs. front yard. 
• Cannot consume in your hotel or rental unless they’re specified as marijuana-friendly. (Note: there aren’t many of these establishments in Michigan.) 
• Cannot consume on the property of a cannabis dispensary. 

What you CAN do: 

• Can consume in a Michigan State Park, but only in your tent or camper—not around the campfire, in an official park cabin, on a hiking trail, or at the beach. 
• Can enjoy cannabis at one of the many licensed cannabis events in Michigan or one of the consumption lounges open in the state. 
• Can smoke on private property, but it still needs to be out of sight of the public.  

Other important things to note: 

• It’s illegal to move cannabis across state lines. If you’re visiting Michigan, please consume your cannabis here before leaving for home. 
• Selling cannabis, in any amount without a license from the State of Michigan, is illegal. 
• If you’re a medical marijuana patient from outside of Michigan, your medical card and an ID are valid here.
