Early Warning System

The Local Early Warning System (LEWS) is to be used to report any concerns relating to specific batches of illegal drugs or any newer and currently unregulated compounds (i.e. NPS/Legal Highs).

This system will enable the reporting and collation of information in order for Doncaster to identify patterns of use; any batches of a substance that may be causing concern; toxic adulterants that may be causing harm or any unusually pure compounds that are increasing the potential for accidental overdose. Should reports be confirmed, through a process of verification by Doncaster, we will then be in a position to disseminate an alert to all relevant agencies and those signed up to the Local Early Warning System.

Should you encounter any type of these issues; then please report the incident immediately via the LEWS reporting form below. Please give as much detailed information as possible.
