Police Bristol, England are urging bar owners to spray the colorless oil WD-40 on toilet lids, sinks, and other "flat surfaces" that customers use to lay out lines of cocaine. From Reuters:
"A chemical reaction takes place with the cocaine that causes it to congeal and become a mess so it's unusable," a police spokesman said.Link
