Two years after Ohio opened its legal adult-use marijuana market, state consumers are paying substantially more for cannabis than shoppers just across the border in Michigan — a gap that analysts say will influence where people buy even as Ohio lawmakers have moved to criminalize bringing out-of-state marijuana into Ohio.
Price disparities persist
Data from the WeedBuddy Cannabis Price Index through July 31 show a stark contrast: the cheapest ounce listed in Ohio was $112, while in Michigan the cheapest ounce was listed at just $6.99. Median prices narrow the gap but still leave Ohio at the top among four comparison states — Ohio’s median ounce price was $147.35 compared with $99 in Michigan, $120 in Arizona and $110 in Colorado.
| State | Cheapest ounce | Median ounce |
|---|---|---|
| Ohio | $112 | $147.35 |
| Michigan | $6.99 | $99 |
| Arizona | $49.99 | $120 |
| Colorado | $16.73 | $110 |
For smaller purchases, price differences are also clear: the index shows a median price for an eighth of cannabis flower at $35 in Ohio versus $20 in Michigan.
Why price matters
Experts and advocates say price will be a key factor in where consumers decide to buy. Morgan Fox, political director for the National Organization for the Reform of Marijuana Laws, said cost influences purchasing patterns and cross‑state travel.
"Price is going to be one of the most important aspects in terms of determining where they purchase cannabis," Fox said. "People were already used to driving to Michigan to purchase cannabis, so as long as there's still a massive price differential, they're probably going to continue doing so at least for the foreseeable future."
That dynamic carries particular weight in Ohio communities near the Michigan border and in larger population centers with stores and dispensaries accessible across state lines. The price differences reflect a range of factors including taxation, local market competition, supply levels and regulatory frameworks — but the index does not supply the breakdown for why prices vary so widely.
New state law restricts cross‑border buying
At the same time, Ohio Republican lawmakers enacted a new law that took effect earlier this year and altered the voter-approved framework that legalized recreational sales in 2024. Among the changes, Senate Bill 56 made it a crime to bring legal marijuana from another state into Ohio.
Under the law, possessing marijuana that cannot be verified as purchased in Ohio or verified as grown in Ohio carries the same penalties that applied under pre-legalization prohibition, according to public descriptions of the legislation. The law also imposes packaging and storage requirements, including a ban on possessing marijuana outside its original packaging and a requirement that drivers store marijuana in their trunks.
Advocates worry the criminalization provision may catch consumers unaware. Fox said many people who previously crossed state lines to buy cannabis when Ohio was still under prohibition may continue to do so out of habit, even if the legal risks have increased.
Practical effect for Ohioans
For Ohio consumers weighing whether to buy in-state or travel to Michigan, several practical factors now come into play:
- Price: In many cases, Michigan offers substantially lower per‑ounce and per‑eighth prices.
- Legal risk: Bringing legally purchased out-of-state marijuana into Ohio can carry criminal penalties under the new law.
- Packaging and transport rules: Ohio requires original packaging and that marijuana be stored in the trunk while driving.
The interplay between market forces and legal restrictions could shape consumer behavior for months or years. If Ohio retailers lower prices or increase competition, the cross‑state incentive may shrink. Conversely, if price differences remain wide and enforcement of the new law is uneven, some Ohioans may continue to purchase out-of-state despite the risks.
Regional context
Ohio’s adult-use sales began in August 2024, following a voter-approved legalization measure. Neighboring states have taken different approaches: recreational marijuana remains illegal in West Virginia, Indiana, Kentucky and Pennsylvania, while Michigan has an established legal market that appears, at least by the WeedBuddy index, to be undercutting Ohio prices.
For now, the combination of higher prices in Ohio and a legal ban on bringing in out-of-state purchases poses a difficult choice for consumers balancing cost and compliance. State regulators and lawmakers have not published an immediate plan to address the price gap; market adjustments and further legislative action would be required to change that calculus.
