Sobriety tests for marijuana a concern as voters weight legalization

STATE HOUSE — With less than eight weeks until voters decide whether to legalize the adult use of marijuana in Massachusetts, Transportation Secretary Stephanie Pollack said Wednesday she is concerned that there is currently no way for police to test if a driver is under the influence of marijuana.
"One of the concerns with marijuana is, it is clear at some point, you are impaired … but we don't have a test like we do for alcohol," Pollack said on Boston Herald Radio. "If the initiative passes, how are we going to be able to enforce the under the influence law?"
