Americans are cool, hip and otherwise chill with pot in their town, but aren't sure they want to get much closer than that. A CNBC All-America Survey finds that 56 percent of Americans would view it as acceptable if a business sold marijuana in their city or town, assuming it were legal in their state. Support, however, declines to 48 percent when asked about a business selling marijuana "in or near your neighborhood." Still the poll of 800 Americans across the country conducted by Hart-McInturff is part of a growing set of surveys showing increased support for legalization of marijuana. In the CNBC poll, a majority in each of the country's four geographic regions found it acceptable for marijuana to be sold in their home town. Support was weakest in the South, but 50 percent still found it acceptable for pot to be sold. In the West, 66 percent found it acceptable. However, views were less supportive on two other issues. Just 34 percent of Americans said they would invest in a business that grew or sold marijuana. And just 28 percent of Americans would consider a job at such an establishment. Views were most positive among Democrats, independents and those ages 18-34. The least supportive groups included those ages 65 and older, Republicans and tea party members. In general, those with at least some college education were more supportive of marijuana in their town than those with just a high school education or less. However, support was fairly uniform across income groups. The survey was conducted March 13-16 by Hart-McInturff, Democratic and Republican pollsters. It had a margin of error of 3.5 percentage point.
