Utah lawmakers have voted down a Democratic effort to keep intact a voter-approved plan to legalize medical marijuana in favor or a compromise bill.

Rep. Rebecca Chavez-Houck asked fellow lawmakers on Monday to “stay in our lane” and keep the original proposal rather than make changes under the agreement between some medical marijuana advocates and state lawmakers.

Her proposal lost in a lopsided Monday vote in the Republican-dominated Utah House of Representatives.

Republican outgoing House Speaker Greg Hughes argued the compromise is an improvement on the original plan, and came after a healthy negotiation process.

Many advocates, though, say the compromise creates nearly insurmountable obstacles for patients seeking access to the drug and are vowing to sue.
