I have epilepsy and sometimes smoke cannabis. Is it dangerous to trigger a seizure or reduce the effectiveness of Keppra?

There does not seem to be a significant interaction between Keppra and cannabis. However, both substances can cause similar side effects such as drowsiness and dizziness. Using cannabis may potentially increase these side effects. Since cannabis is not extensively studied, its effects on epilepsy are not fully understood. It may be best to avoid using cannabis until more research is conducted. If you have concerns, it is advisable to discuss this with your neurologist.
