SANTA FE, N.M. (AP) — New Mexico lawmakers are embarking on an unusual legislative session that focuses on the legalization of recreational marijuana. Efforts at legalizing the sale of cannabis to adults 21 and older faltered during the regular annual session that ended March 20, amid divergent views about government oversight among supporters of legalization. Gov. Michelle Lujan Grisham has called back legislators to the Statehouse to hammer out an agreement on thorny issues of tax rates on pot sales, precautions against child access and court procedures for reversing past cannabis convictions. Negotiations are well underway in private.
