Phoenix New Times:  “t the beginning of this month, Oregon became the third state where adults 21 and older can buy marijuana at retail stores — and Arizona may not be far behind.  But the pro-legalization movement and even Arizona’s medical-marijuana program could still be derailed in the next few years by court rulings or by a new president, Maricopa County Attorney Bill Montgomery maintains.  New Times asked the Republican politician and pot prohibitionist about the start of retail sales in Oregon, where he thinks the law still could be reversed, and about how such a thing could occur when all signs suggest that the United States is growing more, not less, cannabis-friendly.”
