Interesting question. Do you think I should? Do you understand the notions of substance and accidents?
If a communion host which contained poision was consecrated into the Body and Blood of Jesus, then the poision would still be there. The substance of it would change, but the accidents, the outward appearances would remain. Therefore, just as consecrated wine still tastes like wine and will give you a buzz if you drink enough of it, so would consecrated rat poision taste like rat poison and kill me just like regular rat poison.
That's if the consecration would be valid, which it probably wouldn't be. In which case I would not be eating the Body and Blood of Christ at all, but rather some poisoned bread.
This level of question is really below you, Reggie. I thought you understood better than that.
