“I didn’t think I would ever stop”, Abu Salah tells the circle. “After 14 years of buying and selling, hashish, heroin and cocaine, I had lost control of my life. I had no job. I would never speak to my family.”

His story, and the clinic we are sitting in, is an indication of how Palestine’s drug problem is fast becoming a crisis. The towns in and around East Jerusalem have become breeding grounds for addiction, made vulnerable by poverty and a lack of security.

Unlike neighbouring Egypt and Lebanon, Palestine has no historic connection with the drugs trade. Its arrival has been sudden and spectacular, with heroin in particular spreading like wildfire. Al Quds University estimates there are over 6,000 addicts in East Jerusalem today, compared with 300 in 1986.

In the town of Al Ram, pressed up against Israel’s Separation Barrier, degradation has set in. Once a lively suburb of Jerusalem, since 2006 it has been locked out by the Barrier, which surrounds it on three sides. The effect of this sudden disconnection from the city has been devastating.

One-third of all businesses have been forced to close, 75 per cent of youths under 24 are unemployed, and around half of the town’s 62,000 residents have been denied the ID they require to enter Jerusalem.

Al Ram, like neighbouring Abu Dis and Al Ezzariya, has been left in limbo. It is now classified as a mixture of Area B and C, under the terms of the 1993 Oslo Accords, which stipulates Israeli security control with some Palestinian Authority administration. Palestinian police are forbidden from operating here without permission, so residents live with anarchy.

“There is no authority, no security and no police”, says Dr Ajman Afghani of al Maqdese, a social development NGO. “It is easy to steal cars and rob houses, and it has become like a supermarket for drugs”. Palestinian Authority Spokesman Ghassan Khatib acknowledges the problem; “these areas are suffering because we are not allowed to function, and is Israel is neglecting them as a policy.”

Dr Afghani fears that Al Ram has become well known as a safe haven for dealers and users. He points to a small hole in the Barrier outside his window, which he claims is used to smuggle drugs. “Every night they bring heroin through here”. “]
