A new early detection system will allow drug users to flag up bad batches of pills, overdose clusters and lethal new trends.
The RADAR project, run by Public Health Scotland, is designed to help battle our calamitous overdose crisis by identifying where urgent action should be immediately centred.
The early warning system involves a confidential website, which needs no log-in and allows information to be passed on immediately and anonymously, bypassing bodies like police and social services.
