DENVER, CO -

It's a day that some Colorado business owners thought would never come.

They've been given permits to sell pot.

Denver's Department of Excise and Licenses handed out it's first recreational marijuana licenses today.

They gave licenses to 8 retail shops, 30 pot growers, and four other businesses that will make cannabis-infused products like pot brownies.

"We've been selling medical marijuana since 2009," explained marijuana retailer Justin Jones.

"So we're not moving into the retail side of marijuana things and we're very excited."

Recreational pot, for adults older than 21, has been legal in Colorado for more than a year, but retail sales aren't allowed until 8 a.m. on New Year's Day.

Only existing medical marijuana businesses are now allowed to start selling for recreational purposes.

Washington, which is the only other state to allow recreational pot use, plans to have stores open by late spring.
