I-Doser is a program designed to deliver "binaural brainwave audio doses to powerfully alter your mood." What that means is that I-Doser promises drug effects from audio files. In case there's any question about this, the files have names like 'heroin,' 'cocaine' and 'crystal meth.'

Users give I-Doser's promises of drug effects from audio files mixed reviews and there's some speculation that the power of suggestion plays a role. Still, the idea of inducing an altered state using sound waves is an intriguing one.
