Moon Rock Cannabis-Induced Psychosis and New-Onset Seizures in a 20-Year-Old Male.

"Moon rock" cannabis is a type of new and highly potent preparation of cannabis, which is made of a strain of cannabis dipped in hash oil and sprinkled with kief crystals, effectively increasing the concentration of δ-9-tetrahydrocannabinol (THC), the main psychoactive compound in cannabis, well beyond what is naturally found in the cannabis plant. The use of increasingly potent forms of cannabis has far-reaching health implications, including psychiatric and neurologic effects, which are not yet fully understood. This case report summarizes existing knowledge of the association of cannabis use with psychosis and seizures and describes a novel case of "moon rock" cannabis-induced psychosis and new-onset seizures.
