Similar situation as yours yet I got offered several times to so it's just a matter of learning how to spot them and not of going to parties, although that would make things faster (more people would help you ID the professionals). Going downtown around 1am on a Sunday morning should get you the full package, at least in most European cities. City parks, albeit edgy and dangerous, are an almost sure bet. Dealers usually ask you if all is fine and you need help with anything, prostitutes clues are usually attitude and attire, plus they often work in groups. A good undercover cop will be unrecognisable, for obvious reasons (they have to copy criminal behaviour to be successful). Providers have a harder time than their customers (longer jail time and higher fines) hence the secrecy which makes it diffocult to spott them. When in doubt assume it's not a professional, if they are they will make it obvious.
