Been a victim of drink spiking?

Immediately tell someone you trust. If you need urgent help, call 999. Be wary of accepting help from a stranger and don't leave with someone you don't know. If you feel unwell, someone you trust should take you to your nearest A&E department. Tell the medical staff that you think your drink's been spiked.
