There are websites about medical marijuana and articles on the good and bads with taking it however if you want 100% confirmed information about it I would suggest his doctor then if it’s his doctor and not urs that ur meaning. To me its always best to go straight to the source to get the information you want to know.
I totally agree with Kathy, I take CBD for seizures and my neuro(who is amazing ) said THC can be dangerous for epilepsy in high amounts. The medical tapes can be 90% or more THC so it's a rocky road to go down
Russel is right, they have a specific med that has the CBD agent in it, along with over the counter meds. It’s the CBD in the marijuana that has the therapeutic anti-seizure effect, NOT the THC — which causes the euphoria and comes from vaping or smoking. I don’t know if you can talk to his doctor about it?
Might want to ask about seeing what is available as a counter effect then to lower the chances of him having seizures or something that just might help without risking up the seizures percentage rate.
Speak with the neurologist. If he takes AEDs it can be risky to use others meds or supplements.
