The Home Office Forensic Early Warning System (FEWS) was set up to identify emerging new psychoactive substances in the UK. Since inception in January 2011, FEWS has identified 18 substances seen for the first time in the UK, a number of which are already controlled under UK legislation.
The results from FEWS are passed to the Advisory Council on the Misuse of Drugs (ACMD) which keeps drug-related issues under review, including new psychoactive substances. The current availability of substances identified by FEWS is being monitored and, as appropriate, individual substances will be reviewed by the ACMD and advice provided to the Government.
The FEWS annual report published in May is available at:
One new substance has been identified in the UK since publication of this report.
