She did get a lot more agitated and belligerent after she had been sitting by herself for awhile.
But if she had ingested that much right before they arrested her I would think it would have either made her visibly psychotic or worked its way through her system by the time she killed herself.
eating marijuana doesn’t make it psychoactive at all. it has to be heated to a certain degree or dissolved into an oil or other fat for the human body to get high from it, because THC isn’t water-soluble. If you could get high from just straight eating it, people would be doing that.
