My DC recently was given some information about so-called 'legal highs'. This term bugs the hell out of me. It refers to drugs which are totally unregulated and have not gone through the proper channels that drugs need to go through before distribution to the wider public. So they are 'legal' by account of the fact that they haven't been made 'illegal' because the system cannot keep up with the rate that they are being developed and churned out.
Surely we can come up with a less innocuous term which conveys the Russian roulette nature of this stuff.
