View from the Solent (I can't find the blog - is it gone?) left a comment a few posts back with a link to this.
Yes, in the wake of Electrofag come the Electrojunkies! Some even report 'physiological effects' from listening to the new form of legal high - sounds.
The video is full of hysterical adults insisting that listening to sounds will make their kids rush out and buy heroin. None have, or they'd have reported it. Nobody is allowed to think that the teenagers in the video are putting on any kind of act to wind up the adults because we all know kids don't ever do that sort of thing. Sounds make them do it.
The adults want to put a stop to it. How? You can't test for residual sound metabolites. What will they do - test the kids' skulls for echoes? If you have a teenager and they are behaving oddly, that's because they are a teenager. If they are not behaving oddly then you'd better keep a close eye on them because that's abnormal. They are up to something.
You can produce physiological effects with sounds. The most obvious one being deafness from listening to Nazareth at full volume through headphones. Perhaps less widely known are the tricks you can play with subsonics, sounds below the range of hearing. A low frequency tone can make your eyes vibrate and you'll think you're seeing strange ghostly shapes in your peripheral vision. A high-volume tone at around 19 Hz will make most people's bowels spontaneously evacuate. Nobody can hear it so they won't know why they are suddenly sitting in something warm and damp. Must get a tone generator and wire it into the sound system at an ASH meeting.
High-pitched sounds are used to drive teenagers away because we oldies can't hear those sounds any more. Feel the pain, young 'uns.
These aren't dangerous. I doubt anyone could become addicted to shitting themselves and any who do are the sort who needed serious help anyway. There is no reason to suppose that listening to tones is a gateway to crystal meth. Even if some of those sites do link to drug-stuff sites, so what? If the kids wanted to find that stuff, they'd find it. If they don't want to find it they won't follow the link. There's no need anyway - most of that stuff is available behind the bike sheds.
There are far more dangerous sounds out there. Listening to Nick Clegg talking about the smoking ban is bad for your blood pressure and can make your head turn inside out. Listen to the Dreadful Arnott for too long and you'll experience an urge to burst your eardrums with cocktail sticks, as well as spontaneously catching scabies and head lice.
These sounds are a fad. No adult will admit to having tried them - and you just know they have - because to do so would mean they'd have to admit that they didn't get the urge to seek out Filthy John the drug dealer and give him the keys to their car in exchange for a little bag of Vim. The kids are having a hell of a laugh at the adults' expense here.
What's next? Looking at pictures of politicians can make you psychotic?
Oh, wait, that one's true.
