How it works

Okay, the fact that these guys are marketing the software as "drug replacement" is pure sensationalism. This will not affect you the way drugs will. However, there is valid scientific basis to the process that's being applied here. If you play a low, oscillating tone to your brain for a long enough period, your brain begins to synchronise electrically with what it's hearing. By studying the frequencies your brain works at when performing different tasks, various researchers have been able to postulate that certain frequencies correspond to certain brain states. So you get products like this that do a good job of sending you to sleep or helping you study better, stuff like that.
The process takes time, so typically you require a session of no less than 40 minutes with absolutely no disruptions, and preferably with your eyes closed.

For fellow audio nerds like wagaboo, this is how it works: Most of the tones that have an effect are in the ultra-low frequencies, around 2-18Hz. These frequencies are so low that we can't hear them as audio, and any speaker that tried to play them back would probably explode quite quickly. So instead, the effect is created by offset.
Say you wanted a 4Hz tone. You play a 100Hz tone into the left ear, and a 104hz tone into the right ear. This creates a 4Hz offset, which is what you're after. Since the sounds are coming in separate ears, your brain perceives the difference as a kind of swirling, rotating sound, a bit like a helicopter. This is also why it won't work on speakers - you have to have the tones coming in separate ears for your brain to be able to set up the perceived oscillation.
That's the science bit.
Now, the hippies have been quicker to embrace this technology than the rest of the community. Products like this one stem from a new age belief that class A drugs put your brain into different states of oscillation, so this is an attempt to recreate those states. However, the assumption is fundamentally flawed. Drugs don't affect you electrically, they affect you chemically. What you experience on drugs comes from heavy toxins in your system which your body then overcompensates against by releasing floods of endorphines or dopamine or serotonin or whatever.
Point is, you could wire someone up to monitor their brains and then spike them full of heroin, but you wouldn't get any meaningful data that could be applied to software like this because the euphoria you feel isn't because of the electrical activity in your brain, it's because of chemical activity.
So, in short, Brainwave Synchronisation is a valid science, but it's fairly pointless to apply it in this manner. In fact, it's quite likely to be dangerous, because all you're doing is attempting to duplicate the electrical brain state of someone who was tripping off their heads. NOT the euphoria but rather the state of mind.
