Koreans are latching on to what is being touted as "audible drugs" in the form of five-minute MP3 music files, in no fewer than 10 categories and 73 sub-categories. On "i-doser" sites, in addition to "antidepressants," "sedatives," "analgesics," "stimulants" and "soporifics," those that supposedly mimic the effects of liquor, drugs or aphrodisiacs are especially popular, including "alcohol," "LSD," and "cocaine."

A website providing them for free was set up here on Saturday and around 150 user reviews have already been posted, with each review getting between 100 and 1,000 hits. The site does not explain who developed them and how and whether they have been medically proven. According to the site, they trigger psychological changes by stimulating alpha wavelengths (7~13Hz) in the brain which leads to a calming sensation, or beta wavelengths (14~30Hz) which causes tension or excitement.

Experts say this may sound convincing but is improbable. I-doser became popular last year on websites overseas, including Italy. But there is no mention of the company that manufactured them or any clinical trials.

Police say they cannot stop the circulation of the files. An official at the Cyber Terror Response Center at the National Police Agency says they are not illegal as being they are neither illicit drugs nor obscene.
