PORTLAND, Maine (AP) Maine is trying again to hire a consultant to help the state craft rules about the legal sale of marijuana.

Voters in Maine decided to legalize marijuana in 2016, but the process of crafting regulations has been time consuming. The state released a request for proposals on Monday saying it’s looking for the consultant to help put a regulatory structure in place.

The state awarded a $200,000 bid for a consultant last year to BOTEC of Los Angeles, but another bidder appealed that award. The state then decided to rescind the bid award because officials felt the bid wouldn’t withstand the appeals process.

The new bids are due by Feb. 14. The Maine Legislature eventually needs to vote on proposed marijuana rules. When rules will be in place is uncertain.
