Abstract
 Aims

As legalization of medical and recreational marijuana (MJ) continues to spread, topping headlines and ballots across the country, conversations about MJ often highlight potential benefits. Not surprisingly, national trends show the perception of risk and harm related to MJ is at an all-time low. This view persists despite investigations which highlight significant cognitive and neural alterations in MJ smokers. Given the rise in MJ use, specifically among youth, it is critical to determine if patterns of MJ use can predict impairments in cognitive functioning and white matter alterations.
