The latest poll of Arizona voters has found that the legalization of recreational marijuana is a coin flip.

The study, by Data Orbital, found that 45% of voters are opposed to the legalization initiative, Proposition 205, while 44% support it, a local NBC affiliate reported. The margin of error for the poll is 4%, meaning the vote could go either way.

Polling numbers in Arizona have for months shown that rec faced a slightly uphill battle. As recently as late September, a poll from Predictive Insights found Prop 205 trailing by four points, 47%-43%, the Phoenix New Times reported. And that’s an improvement from earlier in the year, when two separate polls found Prop 205 trailing by even bigger margins.

Yet another public opinion study, however, found in August that the initiative was supported by 50% of voters.

The bottom line, it seems, is that the rec campaign in the Grand Canyon State could come down to the wire on Election Day.
