We have to be very careful throwing about statistics about spiking and claiming there is a new epidemic of it and women are at more risk from it now than they ever were. The evidence is just not there to support it. An increase in reporting may well come from a heightened awareness. Whenever there is a well publicised case, reports of spiking go up.
Here’s what is known:
Spiking with drugs is not a new phenomenon (indeed, we were told to be very aware of it in the 90s) and it makes up a small percentage of spiking incidents.
Needle spiking is actually incredibly difficult. The likelihood of someone being needle spiked and being unaware of it is very low. Think about what it takes to get a vaccination, these drugs are not so potent that a small needle stick could get enough of a substance into your bloodstream to render you incapacitated.
Most spiking reports when presenting at A&E are found not to have anything other than alcohol in the body. Some of these drugs can clear the system within hours, but most are still detectable in urine after a day or two. Even GHB, which goes through the system quickest will still be there 12 hours later. If you are presenting at A&E, you will usually be tested within that time.
The vast majority of spiking incidents involve alcohol only. The most common is being given a double measure when you thought it was a single. In many cases being way more drunk than you expected to be in a short period of time can feel like you’ve been drugged (dizziness, unable to walk, disorientation).
Rather than focusing on where your drink is, keeping your hand over it etc, the most important thing you can do to keep safe is, make sure you are there when your drink is ordered.
