DENVER (AP) — Legal marijuana sales in Colorado are set to start on Jan. 1, or so the law says. Knowing when the recreational pot shops will actually open, however, is anyone’s guess.

The state’s 160 hopeful pot shops are mired in red tape and confusion. None knows yet when or if they’ll be allowed to open. Not a single shop will clear state and local licensing requirements until about Dec. 27.

Many of the applicants are still waiting on inspections, local zoning hearings and background checks before finding out whether they’ve been approved to open their doors to adults over 21.

Marijuana tourism companies that already lead bring-your-own pot tours in Colorado are putting off new trips, unsure where they’d bring tourists looking to buy legal pot, not just smoke it.
