Ontario, Oregon Dispensaries: What Idaho Buyers Should Know

More than 90 percent of the customers at Ontario's dispensaries were estimated to come from Idaho, according to a local estimate in a June 2024 Portland Monthly report, in a town of about 11,600 people. That single number explains the traffic on the bridge over the Snake River.

Why Ontario became the closest legal counter to Boise

Ontario legalized cannabis retail in 2018 after earlier opting out; the tiny town of Huntington, Oregon, had served the region first. The Idaho Statesman reported in July 2019 that Idaho customers waited in line for more than three hours when the town's first store opened.

What Oregon lets you buy

Oregon's state tax on adult-use sales is 17 percent, with up to 3 percent extra where a city or county adds its own, according to Oregon's revenue and cannabis agencies. The Oregon Liquor and Cannabis Commission states that taking marijuana across state lines is a federal offense.

What happens when you cross back into Idaho

Payette County Sheriff Chad Huff told the Idaho Statesman in July 2019 that his office had no plans to change its enforcement policies for customers who buy in Oregon and return to Idaho, which means the sheriff's existing policy applies, not a safe harbor. Other counties set their own priorities, and the Idaho State Police enforce state law on the interstate.

How to keep an Oregon trip lawful

• Buy within Oregon limits — the OLCC daily limits apply per person, and shops may check IDs against them
• Use it in Oregon only — Oregon bans public use, and impaired driving is illegal in both states
• Never carry it across the line — this is where the Idaho and federal offenses begin
• Do not mail or ship it — shipping across state lines is a federal offense
