Over the summer there was some media reporting about 'sweets' laced with cannabis, amongst other things. Here are some resources that you might find useful:
The Surrey Safeguarding Partnership and Catch-22 have produced this helpful leaflet: Edibles: Information for Parents & Carers
Ealing Grid for Learning has a ‘toolkit’ about edible cannabis, which includes a powerpoint presentation from the Metropolitan police here: Safeguarding alert: Edible drugs disguised as sweets
Another resources is: Cannabis Edibles Information Sheet (SORTED)
