Cannabinoid Hyperemesis Syndrome
I've seen cannabinoid [5] hyperemesis syndrome several times in the past few years. It occurs in daily to weekly pot users [6]. Very rarely, it can cause cerebral edema, but it is also associated with seizures and dehydration that can lead to hypovolemic shock and kidney failure.
