Sorry to kill your fun, but I-Doser is a scam.
Binaural beats are scientifically proven to have an effect on your brain. By playing differently timed beats to each ear, the interference between the brainwaves your ears trigger can alter your overall brainwave pattern. Normal brainwaves of an awake human are in the alpha or beta states. The beta state is a higher activity state that is experienced when focusing. Alpha is a more relaxed state. By playing binaural beats, the subject may be pushed even deeper to the realm of theta waves or forced into the realm of beta waves.
Now for how I-Doser is a scam. Being in the theta brainwave state is not equivalent to having ingested black tar heroin. Being in the beta state is not equivalent to having snorted a line of cocaine. Even though the principal behind I-Doser is legitimate, the I-Doser company puts no effort into researching their published binaural beats. They essentially just use one of the many existing binaural beats generators, mix it a little, and try to sell it to you for absurd amounts of money (usually $15-20). They've got so many different 'drugs' because it literally takes them five minutes to create a new one, give it some bullstuff name, and publish it on their site. Assuming that the beats do actually affect your brain in some way, which in itself is probably a stretch, it's literally impossible for the effects of I-Doser to be remotely similar to drugs.
