Reckon I had my drink spiked once - Was at a late outdoor beer bar (well after hours) with a mate. Drunk and focused on conversation, I had my beer on the top behind me, took a drink and noticed a horrible acrid taste - reaction was to spit the beer out into the gutter immediately. Paid the bill and immediately left. I could have been mistaken - but a beer doesn't go from tasting normal on the first two 'swigs' to tasting bitter and acrid like that in the matter of a few mins. So - is getting a drink spiked common? - No, I don't thing so, but its also not unheard of either. How do you know 'what' people spike drinks with ??? - It could be just whatever 'cocktail' they got hold of, made or purchased earlier... it could be a mixture of things in a capsule thats tipped into the drink... One thing for sure - there is no SOP or specific recipe that criminals follow. Its also possible the young lad was on 'something' and whatever he was spike with (if spiked at all) interacted and compounded his problem. After reports he fell off his stool, its also possible he suffered a head injury that wasn't picked up on the initial visit - and he succumbed to his injury while sleeping off his evening - the cocktail of drugs part of the story could simply be a red-herring.
