The patchwork of laws, which vary by state and often by county, have created similar commuter-propelled booms in other parts of the country as well, said Mason Tvert, a partner at VS Strategies, a national cannabis policy and public affairs firm in Denver.

Texans travel to Colorado to stock up on their favorite strains or edibles, and Indiana residents make the trek to Michigan, he said. “Demand will be met by either the illegal market or by a legal market in another state,” Mr. Tvert said.

That proposition, and the larger economic equation, are not lost on officials in Idaho.

Last year, the state approached two million residents, a swell attributed largely to people moving from California and looking for overall cheaper costs of living. Only Florida grew faster.

At the same time, property taxes have increased 20 percent since 2018, according to a report from the Idaho Center for Fiscal Policy, a nonpartisan group. And the state’s budget — currently showing a surplus — is expected to come under strain, the group noted, citing legislation that cut income taxes by roughly $500 million over three years even as population growth put new demands on health care, education and transportation.

Some longtime residents of the state are tired of seeing the marijuana tax dollars go elsewhere as prices increase from the newer residents arriving.
