The mainland's first National Drug Prevention Exhibition has opened in Beijing with graphic warnings on the dangers of addiction. Addictive drugs - including opium-bearing poppy plants, heroin and 'ice' - are displayed at the Military Museum. The exhibition, highlighted by the slogan 'Yes to life, no to drugs', shows video footage of addicts writhing in pain, screaming and vomiting as they suffer withdrawal symptoms while in custody. Photographs of drug dealers under arrest are displayed alongside confiscated AK-47 rifles, pistols and knives. Officials have acknowledged drug addiction is no longer 'a foreign problem', with the number of mainland drug addicts soaring rapidly in recent years. Photos of the abscess-covered bodies of young addicts underline the point. Official figures say there are 540,000 registered addicts between 17 and 35. 'I hope the Beijing Government solves the drugs problem here and drugs are banished from the rest of the world,' wrote Zhang Wei, a middle school student, in the visitor book.
