Does smoking pot cause nocturnal epilepsy?

Not typically: Virtually anyone's brain will seize if you do enough bad things to stress it, in research it is common to model epilepsy by placing certain irritating chemicals on the brain of mice. While the effect of marijuana on lowering one's seizure threshold (tendency of the brain to have seizures) isn't that clear, it is an illicit substance and may contain things like Cocaine or meth, that cause seizures.

Not likely: In fact, there are many claims that marijuana reduces seizures, and in some people actually makes them seizure-free without other anticonvulsant medications. This is not proven, but there are cannabinoid compounds which have been shown to have anti-seizure activity. All that being said, individual reactions may be very different, and there may be folks where it could set off seizures.
