An Elway Research poll released January 4 found more support for than opposition to marijuana legalization in Washington state, but support was under 50%. When asked if they favored legalization, 48% said yes, with 45% opposed.

That marks a decline in support from the last Elway Research poll in July, when 54% favored legalization.

The poll results come just days after New Approach Washington handed in over 355,000 voter signatures in its bid to get its Initiative 502 on the November ballot. The initiative would legalize the possession of up to an ounce of marijuana by people 21 and over and would regulate and tax marijuana sales at stores operated by the state Liquor Control Board. (All liquor stores in Washington are also operated by the state.)

The Elway polls asked generic questions about marijuana legalization. A November KING-TV/Survey USA poll that asked about specific provisions in I-502 found greater enthusiasm among voters. That poll had support at 57%.

Noting that the Elway Research poll only asked the generic question, New Approach director Alison Holcomb told the Seattle Times it didn't mention provisions in I-502 that are popular with voters, such as age restrictions and designating marijuana tax revenues for health and prevention programs.

"Our research over the years has shown us that voters really care about what the details are," she said.
