Gahanna Cannabis Guide: Columbus, Ohio

Columbus is Ohio's seat of government and its fastest-growing big city, with Franklin County adding residents faster than any other Ohio metro over the past decade and Ohio State University enrolling roughly 60,000 students on a campus that borders the cannabis retail corridor directly. That combination of political weight, population growth, and a massive 21-and-over college population makes Columbus the state's highest-volume cannabis market by dollar sales.

Two years after recreational sales began, Columbus dispensaries compete hard on price and selection, and that competition only intensified after Senate Bill 56's March 2026 hemp ban pushed customers who used to buy delta-8 at gas stations into licensed storefronts instead. Expect the deepest flower and vape menus in the state here, along with the earliest access to new cultivator releases, since several of Ohio's largest processors treat Columbus as a launch market.

Retail clusters along the High Street spine from German Village north through downtown, Victorian Village, and Clintonville; on the west side along West Broad Street, Georgesville Road, and Sullivant Avenue; and on the northwest side at the Bethel and Sawmill intersection. Grove City, by contrast, has turned down dispensary permit after dispensary permit, so the southwest suburbs still drive into the city to shop.

Ohio became the 24th state to legalize adult-use cannabis when voters approved Issue 2 in November 2023, and the first recreational sales rang up on August 6, 2024, through dispensaries that had been serving medical patients since those sales began in January 2019. Two years later, the market has matured fast: Ohio dispensaries rang up about $1.12 billion in combined medical and adult-use retail sales over the twelve months through March 2026, up 35% year over year, with flower the largest category by far and vapes second at roughly $291 million, up 36%, according to Headset data reported by Shanken News Daily.

The biggest 2026 change came from Senate Bill 56, signed in December 2025 and effective March 20, 2026. SB 56 folded the medical and adult-use programs into one regulatory framework under the Ohio Division of Cannabis Control, split edible potency caps so medical patients can buy stronger packages than recreational shoppers, and made it a violation to possess cannabis bought outside Ohio — every gram in your pocket now has to trace back to an Ohio-licensed dispensary or your own legal home grow.

SB 56 also shut down Ohio's parallel hemp market. As of March 20, 2026, intoxicating hemp products — delta-8 gummies, THCA flower, THC seltzers — can no longer be sold at gas stations, smoke shops, or convenience stores. Anything with more than 0.4 milligrams of total THC per container is now legally marijuana, and it can only be sold through a licensed dispensary that tests and labels it the same way it tests flower and vapes. One narrow exception survives: in July 2026 a federal judge blocked enforcement against ten hemp-beverage makers and the stores that stock their drinks, so a handful of THC seltzers are back on some Ohio shelves while the state appeals.

Adults 21 and older can possess 2.5 ounces of flower or 15 grams of extract and grow six plants at home, twelve per household, locked up and out of public view. Adult-use purchases carry a 10% state cannabis excise tax on top of the 5.75% state sales tax and local sales tax, roughly 16.5% to 17.5% all in. Delivery is still not legal for adult-use customers — SB 56 authorized medical-only delivery, but the Division of Cannabis Control had not finalized those rules as of September 2026, so every purchase in this guide assumes an in-person dispensary visit.

Ohio dispensaries sold about $1.12 billion in the twelve months through March 2026, up 35% year over year, with vapes up 36% and pre-rolls exploding from near zero to roughly $7.4 million a month, per Headset data reported by Shanken News Daily. The March 2026 hemp ban under SB 56 pushed a wave of former gas-station and smoke-shop customers into licensed dispensaries for the first time, and operators in college towns and border cities reported the biggest foot-traffic jumps. Watch for the Division of Cannabis Control's medical delivery rulemaking, which could reshape how patients shop before the end of 2026.
