Marijuana legalization on the ballot in several states

 Voters in three western U.S. states go to the polls on Tuesday to decide whether to legalize marijuana for recreational use in a move that could spur a showdown with the federal government, with polls showing legalization ahead in Washington and Colorado.

If voters approve the measures, the states could become the first in the country to legalize the recreational use of pot. Each of the initiatives would see marijuana taxed and would regulate its sale in special stores to adults age 21 and older.

Surveys show legalization measures ahead in Washington state, where campaign finance records say its sponsors have raised $6 million, and Colorado, where backers have pulled in nearly $2 million. But legalization was trailing in Oregon, where a grass-roots campaign was struggling to sway voters.

A survey of 932 likely voters in Washington state released on Saturday by Public Policy Polling found 53 percent support legalization, with a margin of error of 3.2 percent.

Legalization was also ahead in Colorado, where a recent SurveyUSA poll of 695 likely voters conducted for the Denver Post showed 50 percent in favor and 44 percent opposed. The survey had a 3.8 percent margin of error.

But in Oregon, legalization was trailing with just 42 percent in favor, according to a survey of 405 likely voters by Elway Research for The Oregonian. The poll had a margin of error of 5 percent.

Meanwhile, a Massachusetts ballot initiative on Tuesday proposes allowing medical marijuana in that state, and voters in Arkansas are being asked whether to become the first southern state to allow marijuana as medicine. Seventeen states and the District of Columbia allow medical marijuana.
