From BBC News:
Some of Colombia's elected politicians have used cocaine within Congress itself, the vice-president of the country's Senate has alleged. The drug is also being sold there, Senator Edgar Artunduaga said.
"I know names of people who distribute cocaine here in Congress," he said, revealing the results of an investigation ordered by his office. "There are important officials who distribute, and senators and representatives who consume."
Personal possession of small amounts of cocaine and other drugs is not illegal in Colombia, the world's biggest cocaine producer.
