FILE - This April 6, 2018, file photo shows the leaves of a marijuana plant inside Ultra Health's cultivation greenhouse in Bernalillo, N.M. New Mexico would legalize recreational marijuana sales without exceptions for dissenting cities and counties under a rebooted proposal form legislators that emphasizes small business opportunities and ready access to pot for 80,000 current medical cannabis patients. Legalization for the first time enjoys the full throttled support of second-year Democratic Gov. Michelle Lujan Grisham, who set up a volunteer commission last year to vet health and public safety concerns about recreational cannabis and on Thursday, Jan. 16, 2020, pitched the benefits of the pot economy to a gathering business leaders.

FILE - In this Aug. 14, 2018 file photo, a doctor looks at a PET brain scan at the Banner Alzheimers Institute in Phoenix. Two experimental drugs failed to prevent or slow mental decline in a study of people who are virtually destined to develop Alzheimer's disease at a relatively young age because of rare gene flaws.
