Is it safe for my mom to smoke a little cannabis from time to time if she was recently diagnosed with epilepsy? ive heard it even helps sometimes

Seizure and cannabis: Some cannabis components have been useful in severe cases of seizures, previously resistant to other medications alone or in combination. Those have been defined as intractable seizures. Cannabis products are more difficult to standardize as well as other FDA approved meds. I would suggest to ask your mother's doctor to recommend a more traditional approach, until there is further new evidence.
