after 2 hours the stomach content has likely passed into the small intestine so vomiting would not likely be helpful. assuming these pieces are not unusually sharp those tiny pieces of plastic should pass through harmlessly. in the future it is best not to post urgent questions (since your question had a time constraint) but rather call your medical provider or the local poison control center.
i swallowed several small pieces of plastic chopped up in blender. should i take syrup or ippec or just let pass? . this was about 35 minutes ago and i tried to make myself throw up - but with little success. (although several small pieces were swallowed) there were small plastic pieces that were caught in blender. i put nuts in the blender with powder that is very viscous. will it pass thru easily enough? . . . .
