So sorry to tell you that this isn't a myth, it's absolutely frightening! My friends daughter got injected on Saturday night in Nottingham, she was so lucky that she managed to lock herself in the toilet after she realised she couldn't move her arms and legs or shout.
She found an injection site in her arm where they have used a numbing wipe (it wiped off her fake tan).. they had even put a ring on her finger saying 'Cry Baby'.. we have pics of this.
She is a medical student, very sensible girl, hardly had any drinks and was out with her boyfriend!
Sorry, that's nonsense. Numbing creams take 20 minutes or so to work and, even when they do, they only numb the pain of the needle breaking the skin. They do nothing to numb the pain of the needle passing through the underlying muscle.
Then there is the quantity of the drug they would need to inject. Think about a vaccination - they are typically about half a millilitre of fluid, but you usually feel it going in. A sedating drug, injected intramuscularly, is going to require at least 10 times that amount of fluid (depending on the drug used), to have an effect. Unfortunately, there are no sedating drugs that drop a patient without them even being aware of being injected - life would be much easier for anaesthetists if there were!
And, on top of this, we're supposed to believe that she was out of it enough to have a ring put on her finger against her will, but that she had the strength and presence of mind to lock herself in the loo?
It's certainly possible that this girl had her drink spiked, but the injection story does not stack up.
