American Epilepsy Society

Every case of epilepsy is different and the disease is highly variable. Scientific studies help the entire epilepsy community to understand how and why various treatments work and for whom they are effective. Research also helps us understand the correct dose, side effects, and potential interactions with other medications. At present, the epilepsy community does not know if marijuana is a safe and effective treatment nor do we know the long-term effects
that marijuana will have on learning, memory and behavior, especially in infants and young children. This knowledge gap is of particular concern because both clinical data in adolescents and adults and laboratory data in animals demonstrate that there are potential negative effects of marijuana on these critical brain functions.
