Prague’s Drop-in centre for drug addicts has temporarily lost its home base and will operate from an ambulance in the coming months. The ambulance will park in a different part of Prague every day of the week. Prague City Council is assisting the centre to find a new permanent address that it can afford. The centre which helps addicts and arranges methadone substitution therapy was set up in 1991. There are estimated to be from 10,000 to 14,000 hard drug users in the Czech capital.
