This is pretty strange.
If the LSD was squirted onto the meat BEFORE cooking it, it would have been fine. Everyone in the family must have touched the meat prior to it being cooked in order to get dosed.
If they cooked the meat, the heat would have destroyed 100% of the active LSD ingredients that make you trip.
Doesnt seem like LSD at all.
I'm really curious as to what kind of 'test' they performed that told them it was LSD...
Every "accidental poisoning" case I've ever heard of ends with the discovery that the terminally idiotic neighbor/uncle/teenage son put the drugs/poison/dogshit in the food as prank/revenge.
I doubt this will be any different.
