Is Cannabis Legal in Michigan in 2025? Rules and Limits
Yes, cannabis is legal in Michigan in 2025 for adults 21 and older. Here are the possession limits, retail rules, and restrictions that still apply.
Cannabis legality in California vs Arizona: the short answer
Both states are fully legal for adults 21 and up. That has been settled since California's Proposition 64 passed in 2016 and Arizona's Proposition 207 passed in 2020. So the real question is not whether it is legal. It is which state is easier, cheaper, and better stocked when you want to order something.
My pick is California if product range and online ordering matter to you. Arizona if you want a smaller bill at checkout and fewer local surprises. For a delivery order, California. For a quick in-person run, Arizona.

Possession limits are a near tie
California gives adults 28.5 grams of flower and 8 grams of concentrate. Arizona gives 1 ounce of flower, which is 28.3 grams, but caps concentrate at 5 grams. That 3-gram gap is the only number that shifts, and for most people it never comes up. Both states cap edibles by serving size and require child-resistant packaging.

Where Arizona wins
- Tax: Arizona adds a 16% excise tax on recreational sales. California's excise is 15%, then state sales tax and city tax stack on top. Checkout totals in California often land 25% to 30% above the sticker.
- Local rules: Proposition 207 left cities with much less room to ban retail. California lets every city and county opt out, which is why long stretches of the state have no storefront at all.
- Price per gram: Arizona is consistently the cheaper market on comparable flower.
Where California wins
- Brand depth. The number of cultivators, extract labels, and edibles makers is not close.
- Delivery. Licensed delivery reaches most metro areas, and same-day slots are normal.
- Home grow. Six plants per household, no strings attached.
Arizona lets you grow six plants per person and twelve per household, but only when no dispensary sits within 25 miles of where you live. In Phoenix or Tucson that exception almost never applies.
The border rule nobody should test
Do not carry cannabis across the California and Arizona line. Federal law still lists it as a Schedule I controlled substance, and a state legalization law does not shield you from that. Agricultural checkpoints on the I-10 and I-40 corridors are real, and possession across state lines is a federal charge, not a state paperwork issue.
Pick by situation
- Renting with no grow space and ordering monthly: California.
- Living somewhere that banned dispensaries: Arizona is harder to get stuck in.
- Chasing specific brands or rare concentrates: California.
- Watching cost per gram: Arizona.
If you are buying online in California, confirm the delivery address sits in a jurisdiction that allows it. That single check matters more than any tax difference between the two states.
