Whoops.
http://news.bbc.co.uk/1/hi/england/sussex/7772950.stmI have a wreck-head friend who caught the train from Norwich to London earlier this year. He went into the train toilet at the start of the journey to do some k but as he was getting it out of the wrap spilt it everywhere. His solution was to get as much as he could up his nose. After a bit of hoovering around his cavity was full up and all of the k gone.
Next thing he knows, he wakes up on the floor of the train toilet, still pretty out of it. The door to the toilet is open and two policemen are standing over him; he'd passed out and forgotten to lock the door. They quiz him and take his details, then start searching. Aside from a couple of specks around his nose there's no powedery substances to be seen. The officers are baffled and disappointed that they can't arrest him for possession.
What they didn't know was that the bottle of clear liquid in his rucksack did not contain water, but 1 litre of liquid k, worth a couple of hundred quid and a good few grams.
