Heroin users in Scotland are being trained to spot when someone is about to overdose and to step in and help.
The training – which includes lessons on how to use the antidote naloxone - is often led by people who have themselves been addicts.
Taxi drivers and police officers are also being trained, and naloxone being widely distributed, as part of a push to save as many lives as possible.
Reporter Craig Langran investigates whether the approach is working.
