Alaskan voters will decide this year whether to legalise marijuana in the state for recreational use.
The Alaska Division of Elections has told The Associated Press in an email that a citizens' initiative has met all thresholds needed to appear on the August 19 ballot.
More than 31,500 signatures have been verified.
Voters in Colorado and Washington last year became the first US states to legalise marijuana for recreational use.
The language of the Alaska initiative is similar to the Colorado measure.
The Alaska lieutenant governor's office hasn't yet certified the question for the ballot, but it's expected to do so in the coming weeks.
The initiative would make it legal for adults 21 and older to possess up to 28 grams of marijuana and as many as six plants, including three that are flowering.
It also makes the manufacture, sale and possession of marijuana accessories legal but does not allow public consumption of weed.
Anyone smoking in public would face a $US100 ($A112) fine.
