I have listened to a number of these now, using really good headphones and sitting still as you are supposed to, and I quite enjoy them, largely because they sound a lot like the music I already listen to for pleasure. Indeed, there are already lots of sites out there with downloadable binaurals that promise to hypnotize you and help you to quit smoking or beat insomnia. The buzzing sound is supposed to put your brainwaves into an alpha state, which is the state one tries to achieve through meditation. If you play these two pitches at once, they start to combine in a throbbing pattern not unlike a beat. The effect is supposed to come from the fact that they are 'binaural beats' - two different frequencies, one played in each ear. They are made up of a buzzing drone that varies slightly over the course of a few minutes. They often have the names of the drugs whose effects they are trying to duplicate: The tracks will be labelled LSD, cocaine, alcohol ,or something scary like The Gates of Hades. You can buy full-length 'doses' - up to an hour long - and a player for them at, or you can listen to a lot of free ones made by amateurs on YouTube. The Internet is still awash in i-doses, though, and the videos of the fun people are having with them, twisting and moaning.

But then no one could find any real drugs being sold anywhere, and we left the kids alone again. The police chiefs responded that, well, it was still dangerous because the sites that sold them were also leading teens to sites where they could buy real illegal drugs - that i-dosing was a gateway, as it were. The media got hold of this and trotted out some scientists who said no, there was no evidence to say that listening to certain tones actually alters your brain function. These came to the attention of a few small-town police chiefs and high-school principals, who sent messages out to parents telling them to look out for the symptoms of intoxication in teens who had been spending too long on the Internet. media alarm over 'i-dosing' - a teenage fad involving listening to trippy electronic sounds over the Internet and pretending to hallucinate from it - was as brief as these things get: It lasted a couple of weeks, in July, and, being as obviously ridiculous as it was, died immediately and completely.ДЇirst someone noticed a whole bunch of YouTube videos of teens experiencing these sounds on headphones and breathing fast and crying as if they were really tripping.
