My last time going through alcohol WD's was last year, and during the acute phase (that is to say, the first three days or so) you couldn't have paid me to touch weed, I had a bunch but waited until I had passed the aforementioned early phase.
I don't know enough to speak directly to seizures, but if you know what WD's are like, and you know what weed can sometimes do vis-a-vis anxiety, it could potentially be a frightening combination, in my estimation.
Or it could be heaven sent, what do I know? But my thought at the time was no way.
