Cannabis beer: Does it have a market?

Seven years ago, Washington and Colorado became the first states to legalize recreational marijuana. Since then, that list of states and the size of the market, has only grown.

There's brewing interest in something new: cannabis-infused beer. Barry Petersen reports.
