there was about 2gs of ketamine in the bag. he already shit out one that he shoved up his ass (not a good day for him if you could imagine). the size of the baggie was a bit bigger then what you might trypicaly get a dime of pot in.Is it just a tiny plastic baggie? If it is small and there was nothing in it, it should be fine, it should just pass through the digestive system. Let us know if there is more to this story though. And if your friend gets any symptoms like stomach/abdominal pain or constipation he might want to go to a doctor, but normally a small piece of plastic will just pass through the digestive system and come out.
Provided the bag is small and the contents are dangerous....yes.
he went and saw a doctor and they basically told him the same thing. its probably just going to come out the other end. if it doesnt than it may cause an obstruction and he'll need medical attention.
