“You may not use or possess marijuana, medical marijuana or marijuana paraphernalia in any form anywhere on University of Massachusetts Amherst property,” the school’s home page says, noting that federal law prohibits the use, possession or cultivation of the drug at educational institutions, while state law prohibits the use of marijuana anywhere in public — on or off campus — and if you are under 21.

“The academic impact of using marijuana includes lower GPA and delayed graduation,” the warning adds. “If drug testing is required, marijuana use can cause you to lose scholarships, jobs or internships.”

Norton Arbelaez, director of government affairs for New England Treatment Access, which runs a medical marijuana dispensary in Northampton, said it has received a license from the state Cannabis Control Commission for the sale of recreational pot contingent on it passing a final inspection.

“We really see this as an expansion of our business instead of a shift,” Arbelaez said yesterday. “Our priority will continue to be our medical marijuana patients.”
