4.8 Preventing drink spiking

Drink spiking is when another person adds alcohol or another drug to a person’s drink without their knowledge or consent. A person who spikes a drink may be the victim’s friend, acquaintance, work colleague, date or a stranger.

How can venues minimise the risk of drink spiking?

Drinks can be spiked in nightclubs, bars, dance parties, private residences, BBQs, community celebrations and restaurants. Drink spiking is a crime and apparent drink spiking incidents should be reported to police.

It’s difficult for staff to be aware of drink spiking. You’re serving a drink; once that drink is taken away from the bar, you’re not sure who it’s going to, especially if somebody’s buying three or four drinks at a time and taking them back to a group. What happens between the bar and when that person that is receiving the drink drinks it, you can’t observe it the whole way. But you can observe what is happening with people’s behaviour and we have had occasions where a group of two males, two females, are sitting there, everybody’s fine, in a very short period of time one of the girls is slumped, can’t walk properly, and to all intents and purposes appears very affected by alcohol we would assume—showing severe signs of intoxication, but it’s happened so quickly that it appears to be an odd occurrence.

It has occurred in my venue once that I can recall when I was there even, that then the males insisted that they would look after the girl and be taking her home. We had concerns and we said, no, we’ll call her a cab and organise transportation for her and wouldn’t let her go with the other fellows that were there in the group. It was obvious that she wasn’t really familiar with them; they hadn’t been together when they came in to the venue, and we were able to look at CCTV footage and backtrack while they were still in the venue to ascertain, to see that they didn’t all come in together, they were virtually being picked up, I guess they met the fellows in the venue, and then the next thing one of the girls is very very ill indeed.

So we were able to manage that situation but it’s not often that you are able to really join the dots together to see what has happened. It’s not very often. I can’t recall ever one of my staff or in my 30 years or more in the business that I have seen somebody actually spike a drink.

At times we’ve even taken the liberty of getting ID from the person. They weren’t able to actually get it out of their wallet themselves, but we’ve got their ID and made calls to the home to make sure that transport could be arranged and that they got home with the people that they needed to be travelling with, not with whoever may have been with them at that time.

Alcohol is the drug most commonly used to spike drinks as it is relatively cheap, legal and easily available. In many instances, alcohol is added to drinks without suspicion. A person may not easily detect relatively tasteless alcohol, such as vodka, when it is added to their drink.

The most common physiological effects attributed to drink spiking are vomiting, unconsciousness, poor coordination and balance, slurred speech, lowered inhibitions, drowsiness, dizziness, loss of motor skills, impaired judgment, visual problems and nausea. These symptoms are also commonly associated with intoxication.
