PORTLAND, Maine (AP) — The Maine Marijuana Project is calling on lawmakers to override Republican Gov. Paul LePage's veto of a bill to regulate the sale of marijuana, likely in 2019.

LePage on Friday cited several concerns including how the Trump administration is going to treat the federal-state conflict in law.

David Boyer of the Maine Marijuana Project said the veto means marijuana will continue to be sold on an unregulated, black market unless two-thirds of lawmakers in both chambers vote to override the veto.

Meanwhile, Smart Approaches to Marijuana praised the governor for vetoing the "flawed bill." Chairman Scott Gagnon cited "gaping holes with respect to youth access and public safety."

Republican Sen. Roger Katz said the governor's criticism was too late. He said the governor should've been involved in the bi-partisan process.
