HI. My boyfreind had a serious head injury about 2 months ago, very serious, two large contusions on the frontal lobe . He was hospitalized for a month. He is recovering well, but still can t taste and smell. He really likes his weed and hasn t been smoking it, but is starting to crave it and claims that he has researched it and that pot is safe with his head injury. He is also on a lot of antidepressants, an antipschyotic and more. How will pot affect his brain injury?
