Poetry - Link to this poem?

[Stiney]

Was wondering if anyone could post the words to or link to this poem. I think it's called Crop Circles (although it might be Crop....something else), it's about the effect of the drugs trade (cocaine?) on the producer nations, at least thats what I interpreted as, sorry I don't have any more info than that, can't remember any of the lines word for word, google just brings up a bunch of websites about actual crop circles. This might be a long shot but thanks anyways. Don't know if this will help but it was featured at the end of a tv programme about a guy that travels around taking on the toughest jobs in the world and in the episode the poem featured in he was working with the Columbian drug squad. Cheers.
