I have no idea if there is any evidence that cocaine can actually cause epilepsy, although obviously it can exacerbate it. However, my brother-in-law never suffered with epilepsy or any related illness until shortly after he started using cocaine. He was using normal powdered cocaine at first and although I knew he was up to something and could see him changing, things didn't seem too bad. However, he then also started smoking the stuff (i.e. crack). Soon after, he began to suffer with regular epileptic fits even though he had never had one before. Over ten years later and, as far as I know, clean from cocaine (but still using heroin), he still has epileptic fits to this days and has had many of then in front of me. It's ridiculous tothink that if he had nevee tried cocaine then he never would have had an epileptic fit and wouldn't suffer with epilepsy now.
