Small Pupils?

Is heroin the only drug that makes your pupils small? My bf is an ex heroin addict, came home high on something last night. He says it was vicodins and I normally wouldn't believe his lies but the buzz was different, he was just a little more hyper than normal not nearly as intense as the normal H buzz. He used to do pills but quit once he took up H and I don't remember if his eyes were small then (I don't think they were?) But his pupils were tiny and I though H was the only drug that does that. I"m still just as mad either way so it doesn't really matter but I was just curious. Thanks
Your pupils most certainly can be tiny while on Vicodin!

Large doses of all opiates cause constriction of the pupils.
