The legalization of recreational and medical marijuana in several states has brought about more urgent questions about the potential cognitive and neuropsychiatric effects of cannabis use, particularly related to long-term use. Today we talk with Igor Grant, M.D., F.R.C.P., about contemporary cannabis research and how neuropsychologists should consider cannabis use when completing neuropsychological assessments.
