I-Dosing." It's real and on retail at http://www.i-doser.com. The altered state of mind achieved by I-Dosing is caused by binaural beats, in which one ear hears a pitch that is only slightly off key from the pitch played in the other ear. This small difference in pitch causes an eerie fluctuating sound, so that you can hear something like wavering "beats" in the continuous tone (musicians will be familiar with this sound, as it is similar to the fluctuations in sound heard when two instruments are slightly out of tune from each other).
The question is, is I-Dosing dangerous? Probably not. It creates a brain state more similar to that of meditation. In fact, binaural beat therapy to treat anxiety had been in use long ago. However, like many things in life, the thing that makes all the difference is one's perception. With the media portrayal of I-Dosing as a type of "drug music", it has automatically set I-Dosing up for adolescent interest, and along with it, parental concern.Yes, it should really just be called "meditative music," but of course that just isn't interesting enough for the press.
