The fact that they claim to have a track to simulate pretty much any drug under the sun also doesn't help it's credibility IMO.

From what I've looked into it, apparently there's a decent amount of science saying that binaural beats can change your brainwaves and produce certain effects, but... not fucking like. Drug-specific crazy hallucinations and shit people claim to have with this.

(and Cardy, I would suspect something on YouTube would be kind of shit quality. I don't know too much about it, but I'd assume frequency accuracy and stuff would be (theoretically) key here)
