Parents, teachers and authorities in the US have been getting hot under the collar about an alleged teenage craze called 'i-Dosing'.
The craze involves teenagers slipping on some headphones and turning up the music for a so-called "digital high".
According to reports, the craze employs "binaural, or two-tone technology, to alter your brain waves and mental state".
Some users have described i-Dosing's effects to be similar to those caused by taking illegal narcotics. Web site i-doser.com, the company behind the music, sells its 'Recreational Simulations' audio pack as four "doses", likened to for drugs: marijuana, cocaine, opium, and the hallucinogenic cactus peyote.
Oklahoma Bureau of Narcotics and Dangerous Drugs spokesman Mark Woodward has advised parents to prevent their children from joining the craze.
"Kids are going to flock to these sites just to see what it is about and it can lead them to other places," Woodward said.
Many users have labeled the craze a hoax, saying that the tracks sound like nothing more than cheap club music.
Speaking to UK newspaper The Sun, i-Doser.com CEO Nick Ashton said: “Any method that involved experiencing a simulated mood or experience should be taken seriously.”
"i-Doser.com is not dangerous, completely safe, but any user should be aware that this is causing a modification of mood."
