When Canada legalized adult-use cannabis in October 2018, the mailbox was the market. Online sales were about 43% of legal non-medical retail sales that first month, according to Statistics Canada. In Ontario, the government's online store was the only legal channel until the first cannabis retail stores opened in April 2019.
Then the stores opened, and the mailbox lost.
By September 2019, online had fallen to 5.9% of legal sales nationally (StatCan, Dec 11, 2019). Today, online is about 1.5% of Ontario Cannabis Store revenue (OCS Annual Report, FY2024-25). OCS.ca brought in $26.6 million that year, down 20.3%, and the OCS attributes the decline to buyers shifting to stores. Ontario had 1,719 cannabis retail stores as of March 31, 2025.
That is the clearest real-world test we have of mail order against the counter. Now Georgia is about to run a U.S. version, and two U.S. senators want the Postal Service to stop it before it starts.
Georgia's rule
On Sept 30, 2026, the Georgia Access to Medical Cannabis Commission (GMCC) unanimously adopted Rule 351-6-.11. It lets licensed dispensaries deliver to registered patients by certified mail or an equivalent tracked carrier. The signature has to come from the patient, the caregiver or an employee of a healthcare institution, such as a long-term care facility. Nobody else can sign.
The rule is narrow. It covers Georgia addresses only and low-THC oil only, the one product Georgia's medical program allows. The rule text, as reported by Marijuana Moment, lets USPS, a common carrier, the Commission or a carrier the Commission hires make the delivery.
GMCC executive director Andrew Turnage has said the rule "leverages the authority" in the federal order moving state-licensed medical marijuana to Schedule III, and that some patients drive "two hours or more" to reach a dispensary (via Marijuana Moment). Botanical Sciences CEO Gary Long told WTOC on Oct 2 that USPS would be "a primary part" of its plan, with shipments staying inside Georgia and arriving in one to two days. Long called it "a distinctly clinical model" in comments to WABE.
When the rule takes effect, and whether anyone is shipping yet, has not been confirmed on a primary source. One secondary site reports an Oct 26 effective date; CP could not verify it.
The carriers say no
The rule has a problem: the carriers it names won't carry the product.
USPS spokesman Nikolaj Hagen pointed Marijuana Moment to the Postal Service's controlled-substance mailability rules and said USPS has "nothing additional to offer at this time." The USPS domestic prohibited-items list still includes "marijuana (medical or otherwise)."
The private carriers are just as firm. UPS bars marijuana "under any circumstances, even when... for medicinal purposes or otherwise legal under a state's law." FedEx bars it "even if it is legal in the origin or destination state." UPS goes a step further: it won't accept hemp shipments from any location that sells marijuana. If your store sells both, UPS is already off the table for your hemp products.
Georgia's bet is a legal reading. Postal rules allow controlled substances in the mail when they go from "authorized dispensers" under federal pharmacy rules, and the Schedule III order says a state medical certification is enough to permit dispensing. Nobody has tested whether a Georgia dispensary counts as an authorized dispenser.
The senators' letter
On Oct 27, Sens. James Lankford (R-Okla.) and Ted Budd (R-N.C.) wrote to Postmaster General David Steiner asking USPS to keep its ban. CP could not find a primary copy of the letter; the quotes below are as reported by Marijuana Moment and Cannabis Business Times.
"While Georgia does not have the authority to alter current USPS regulations, we are concerned that USPS will alter its regulations to allow for these shipments," the senators wrote, according to those outlets. "We strongly oppose any effort to allow the shipment of marijuana." They also wrote that "this trust in state licensing schemes is not deserved," pointing to Oklahoma, which they said once had "9,178 licensed marijuana grow operations and 2,611 licensed dispensaries." Their ask: "urge USPS to maintain its current regulation that prohibits the shipment of marijuana."
Smart Approaches to Marijuana's Kevin Sabet said USPS "should listen to these senators." DHL told Marijuana Moment it is "monitoring and will continue to comply with all applicable laws." UPS and FedEx did not respond to Marijuana Moment.
Where U.S. delivery stands
Delivery is common in the U.S. Mail is not. Every model in place today is in-state courier delivery: a driver, a vehicle and an ID check at the door.

What this means at the counter
For storefront operators, the near-term answer is simple: mail is not available in the U.S. today. Whatever happens in Georgia, your delivery competition is still a licensed driver in your state, carrying product to a door and checking ID.
The longer-term question is who wins if the carriers open up. It won't be the independent with three vans. Statewide mail rewards scale: vertically integrated operators and multistate operators with central inventory, fulfillment staff and the compliance teams to run tracking and signature records. In Georgia, the licensees ready to ship statewide are the producers themselves.
Canada shows both sides. Stores beat mail decisively once they could open, because customers wanted the product today, wanted to see it and wanted to talk to staff. But mail kept one job: access. OCS says its online store serves towns that opted out of stores. And roughly 156,000 registered medical clients (156,270, Health Canada, Dec 2025) get their cannabis by mail only, because Canada's federal medical channel is direct-ship by design.
That is the U.S. risk for medical-heavy operators. A mail channel would aim straight at homebound, rural and long-term-care patients, the customers your delivery staff serve now.
Policy design matters too. Ontario lets cannabis retail stores deliver, but only with their own employees, and bars stores that operate "entirely or predominantly" as delivery businesses. Maryland limits delivery to micro dispensaries. Massachusetts reserves delivery licenses for equity applicants until 2029. Each rule tilts delivery toward smaller, local operators.
What store managers should watch:
USPS. Any change to Pub 52 or its prohibited-items list is the trigger. Right now it has "nothing additional to offer."
Georgia's first shipment. Whether a licensee actually ships, by which carrier, and how fast.
DEA registration. Whether registered dispensaries get treated as "authorized dispensers" for mailing.
Your state regulator. Watch for rulemakings that copy Georgia's language, and for limits like Ontario's employee-only rule.
Your hemp shipping. If you sell marijuana and ship hemp, UPS is already closed to you.
Canada's lesson for the counter is that convenience alone didn't beat the store. Mail won where there was no store and where patients couldn't get to one. Make sure that isn't your customer.
