The effects of drink spiking vary depending on what you’ve been spiked with. Symptoms could include: 
  • Lowered inhibitions 
  • Loss of balance 
  • Feeling sleepy 
  • Visual problems 
  • Confusion 
  • Nausea 
  • Vomiting 
  • Unconsciousness 
The symptoms will depend on lots of factors such as the substance or mix of substances used (including the dose), your size and weight, and how much alcohol you have already consumed. 

While the onus is on perpetrators to stop engaging in this behaviour, you can reduce your chances of being spiked by: 
  • Always keeping sight of your drink 
  • Being vigilant if you are drinking with strangers 
  • Keeping an eye out for your friends and noticing if their behaviour changes
