Even after more than two years of extensive retail sales next door in Denver, Littleton leaders believe such commerce could do more harm to their community than it is worth. Which is their prerogative, of course. Amendment 64 provides for a local option and that's what the city just exercised. Still, some of the comments in opposition appeared remarkably overwrought. A former high school principal asked, for example, "Are we going to be the place where Nero fiddled and Rome burned, or are we going to have the integrity to say enough?" The Denver we know remains a good place to work and raise families, and far from indifferent to the societal effects of drug use. Yet divided opinion on legalization is inevitable given the inconclusive nature of so many indicators related to pot. Trends in consumption and their effects since the passage of Amendment 64 in 2012 are murky, given the short period of time and the lack of a good baseline in some instances. That's why it's important for the Colorado Department of Public Health and Environment (CDPHE) to continue monitoring usage trends, particularly among youth, as well as health impacts of marijuana sales by collecting data from schools, emergency rooms, treatment centers, traffic stops, and elsewhere. The department has been collecting a lot of data already, and recently advertised for a "marijuana health effects and research manager" to coordinate the effort. Although we are more optimistic than some critics regarding Colorado's ability to manage this social experiment, we've never doubted there would be downsides requiring attention. A recent story out of Pueblo offers the latest example. "What I'm seeing in our nursery is a dramatic increase in babies who test positive for marijuana," Dr. Steven Simerville of St. MaryCorwin Medical Center told Denver Post reporters. "The interesting thing for me is the number of mothers who use marijuana and want to breast feed. They don't believe marijuana is harmful." It's beyond us how any young mother could reach such an irresponsible conclusion, but there is no reason to doubt Simerville's account. Whether his larger point about a "dramatic increase in babies who test positive for marijuana" is a general phenomenon or isolated to his locale is a more difficult question. That's why Colorado will benefit from a broad effort at data collection and analysis. And that's also why, as we said last fall, the jury remains out on whether legal marijuana has been a net success or detriment for Colorado. - --- MAP posted-by: Jay Bergstrom
