1. Marijuana rules of the road:

With Colorado legalizing pot last week, I’ve been waiting for a story about whether the bomb-sniffing dogs at the Denver International Airport will now have an expanded portfolio.

This story on CNN.com says that travelers will not be searched for marijuana per se but that carrying pot through the airport is not allowed. If a traveler is searched for any other reason and pot is found the traveler will be subject to a “$999 administrative fine.”

Does this relatively laid back approach mean that people coming in and out of Colorado will be free to take marijuana cigarettes or brownies home with them? With that in mind, how do the purchase limits — one ounce per transaction for Colorado residents and a quarter of an ounce for non-residents — work? Is there a limit on the number of transactions a non-resident can make in a day or a week?

2. How often is the CBO right?

This article last week by Sarah Kliff, the Washington Post’s terrific healthcare policy reporter, is about whether Obamacare might end up achieving the number of enrollments projected last year by the Congressional Budget Office, or CBO. It’s a great piece, but I’m using it here to demonstrate the need for a different story that digs into this question: How good is the CBO at making projections that then assume a gospel-like aura?

Just about every significant piece of legislation debated in Washington is “scored” by the CBO, a non-partisan office of economists and other policy experts. The CBO’s website describes the scoring this way: “independent analyses of budgetary and economic issues to support the Congressional budget process. The agency… conducts objective, impartial analysis, which is evident in each of the dozens of reports and hundreds of cost estimates that its economists and policy analysts produce each year.”
