The question: How popular is crack? - The Guardian 23rd January 2008

Footage has emerged of the troubled songstress Amy Winehouse apparently smoking crack at her home in east London. The substance is widely regarded as the "down-and-out" drug. "Crack is whack," as Whitney Houston once put it. But is it growing in popularity? Home Office figures show that 28% of drug expenditure in 2003-04 (the most recent statistics) was on crack, compared with 23% for heroin, 20% on cannabis and 18% on powdered cocaine. It is generally bought on the street in small quantities - rocks cost about £10 each.
