DENVER (AP) — Marijuana tourism is on the way to Colorado, but the state will put up signs in airports and borders telling visitors they can't take pot home. That was a recommendation made Tuesday by a pot task force set up to suggest regulations for the drug made legal by voters by year.

The task force agreed Tuesday that that Colorado's marijuana amendment does not specify that adults over 21 must also be Colorado residents to have recreational pot The recommendation suggests limiting marijuana sales to non-residents, but left a specific cap to state legislators.

The task force failed to agree to home-growing regulations and public use rules. Coloradans voted last year to allow adults over 21 to have up to six plants.
