An emergency summit is to be held to discover why occupancy rates at Scotland’s residential drug treatment centres are so low.
It comes as one expert has warned that residential rehab – one of the Scottish government’s key planks in its drugs strategy – is “dying”.
Rowdy Yates from Stirling University said intensive treatment was still needed and denied it was too expensive.
MSPs are due to debate the drugs strategy later this week.
Last month the Scottish government announced a review of its methadone programme.
It followed the release of figures showing that Scotland’s drug deaths in 2011 were at a new high, with methadone linked to 47% of deaths.
