Heroin treatment in Scotland has reached record levels, according to official figures.
About 21,000 people are now using methadone, 10% more than previously thought. And a third of the methadone users are caring children under the age of 16, the government figures show.
Minister for community safety Fergus Ewing said: 'The true scale of the challenge we face is now clear for all to see. As a government we will not take sides in the debate between the 'just say no' and the 'harm reduction' lobbies.
'There is a place for both approaches,' he said.'It is clear that methadone does have an important part to play in tackling heroin addiction. The benefits it can bring in terms of harm reduction are well established.'
