Opium cans

From: "Frank Estrella" franke4x4@sbcglobal.net

While visiting your web site I noticed some photos of can dumps that were indicated to be opium cans. I was just wondering how one is able to determine the difference from food cans or opium cans in these can dumps which are commonly found near old mining camps. In my adventures I have found several can dumps like the one at this link at a chinese camp near Bodie California. is there a way to know if they were opium cans?
