Anne Markel-Crozier, a certified social worker, and Matthew Brasette, an attorney, addressed the crowd at a recent lecture at Stockton University in Manahawkin. They were discussing the use of medical marijuana among older adults in New Jersey.

They had plenty to talk about. According to data gathered from the National Survey on Drug Use and Health from 2015 and 2016, about 9 percent of U.S. adults between ages 50 and 64 had used marijuana in the previous year.
