Lewis is a young occasional cocaine user from the Midlands in the UK.

The 鲍鱼tv set up a video chat between him and two Colombian men who harvest coca leaves and turn them into cocaine using ingredients such as petrol.

One farmer told Lewis: "I don't want to take it because I know what is in it."

The full Our World documentary, Colombia: The New Cocaine War, can be watched at various times this weekend on 鲍鱼tv World News.
